As TMS fades from the airwaves, it's time to wave goodbye to the quarter-finals - and to Sri Lanka, Bangladesh, Pakistan and West Indies. Four titans remain: New Zealand, South Africa, Australia and India.
The semi-finals start on Tuesday - but if your cricket appetite can't wait until then, from tomorrow you can listen to the Champion County game between MCC and Yorkshire from Abu Dhabi. A trio of once (and future?) England openers head the MCC batting order: Messrs Cook, Compton and Carberry.
But make sure you join us on Tuesday morning - NZ v SA gets under way at 01:00 GMT, we'll be here from 00:30. Until then, enjoy a bumper weekend of sport and raise a glass to an astonishing performance from Martin Guptill. TTFN.
"Phil Simmons coming in as coach should unite the West Indies, he's done a very good job with Ireland."
Review of the day
If your alarm clock has just gone off and awoken you for the start of a special Saturday of sport, I'm afraid it's all over down under where it'll be the Kiwis dancing on the streets of Wellington tonight.
Martin Guptill led the way with an astonishing unbeaten 237 at the top of the order as they posted 393-6, and although Chris Gayle (61), rendered largely immobile by injury, got West Indies off to a flier of sorts - indeed, the Caribbean men hit more sixes than the Kiwis - once he departed at 120-5, the game was up for them.

Captain's view
New Zealand captain Brendon McCullum on Daniel Vettori's one-handed catch: "I gave him no chance to be honest,. You saw the reaction of the boys to run from all corners to celebrate. He us a legend of New Zealand cricket, a special man and a cricketer and you can see what his involvement means to us."

Louis Strong: NZ, India, South Africa and Aussies. The best four ODI teams. England had no chance so I don't know why we were surprised.
Captain's view
More from New Zealand captain Brendon McCullum: "The way our team is structured it allows us a licence at the start. For us to be competitive on a regular basis we need to play an attacking style of cricket. We will continue to play like that.
"We know how dangerous the West Indies players are. They are clean strikers. We wanted to make a statement and make it a professional performance across the board. The bowlers made sure we did that. It is great to progress, we will celebrate tonight and then turn our attention to Auckland. We will do our homework and put our best foot forward."
"Guptill's first 100 runs were very classically scored. He played some beautiful straight drives, and didn't take may risks. His hundred was perfectly timed, and he went mental from that point onwards. It was incredible to watch."
Captain's view
New Zealand captain Brendon McCullum on TMS: "That was the greatest innings in ODIs I've ever seen live, the skills that Martin Guptill displayed were once in a lifetime really. Everyone here will remember it for the rest of their lives.
"I'm still trying to work out how we got 394, it's a mammoth score. We knew that they had ball strikers, but the bowlers hung tough under pressure. Dan Vettori wasn't at his miserly best today, but he created opportunities. Trent Boult just gets better and better."
Captain's view
More from West Indies captain Jason Holder: "It was a tough to defend. We were in the game until the 35th over. Guptill played superbly. We dropped him early and it cost us. The ball sat up well on the pitch and he could put it where he wanted.
"It has been a challenge. I had high hopes coming into it, but it has been a rollercoaster. We have learned a lot. It is about learning as quickly as possible. We need to find out where he went wrong and assess what we do.
"I would like to keep the captain's job. It is something I have always wanted to do and I don't think I have done too badly. I would like to thank the supporters who came here to help us."
Bridesmaids again?
New Zealand have often been the bridesmaids of international cricket - reaching World Cup semi-finals in (deep breath) 1975, 1979, 1992, 1999, 2007 and 2011 - but never a final. Can they go the distance this time in 2015?
It should be noted, unlike England, they have won a 50-over ICC global event - triumphing in the ICC Knock-Out (the forerunner of the modern Champions Trophy) in Kenya in 2000.
Their semi-final opponents South Africa have a not dissimilar record - three times World Cup semi-finalists, never a finalist, and won the inaugural ICC Knock Out in 1998.

Riaz and Watson fined
A snippet of news from yesterday's game: Pakistan fast bowler Wahab Riaz was fined 50% of his match fee while Australia all-rounder Shane Watson was penalised 15% of his after their angry clash in Friday's World Cup quarter-final.
Riaz was charged with using obscene language, while Watson was accused of conduct contrary to the spirit of the game when the two faced each other down in a compelling passage of play during Australia's six-wicket win at the Adelaide Oval.
ICC match referee Ranjan Madugalle said: "It was an enthralling contest between Shane and Wahab, but in the closing stages both players crossed that fine line between intense competition and unacceptable behaviour."

Captain's view
West Indies captain Jason Holder on TMS: "It's quite disappointing, we came into this game with high hopes. Martin Guptill took the game away from us with his 200 and we didn't bowl well in the death overs. 393 is a big score but it was a good wicket and I thought we could have put up a better fight.
"I hope it's not the end of Chris Gayle's international career but that's up to Chris. We've been away from home for a long time and so many guys are mentally and physically tired. We'll have a well-deserved rest before the Test series against England."
"He's a nice fellow, Jason Holder, I think he's been burdened with the task [of captaincy] rather prematurely. If you look at Brendon McCullum, he has the breadth of experience that helps his captaincy."

Post update
Captain Jason Holder tells TMS he hopes that wasn't Chris Gayle's last international game.
"Martin Guptill dazzled. He turned this stadium into a little carnival. He hit the ball so cleanly, drives that you've never seen anything like. He thoroughly deserves all the accolades he's getting."
Post update
Guptill also admitted he didn't think he'd ever surpass the 189 not out he made from 155 balls against England in Southampton in 2013. I was at that game and it was a phenomenal innings, but today's knock was on another level entirely.
(Historians may also note that the aforementioned 2013 game also saw the last ODI outing in England colours for Jade Dernbach, who was flogged around Hampshire for 87 runs in 10 overs).
Man of the match
More from Martin Guptill on TMS: "It hasn't quite sunk in, but the boys will have a few drinks tonight and I'll probably hear all about it. Last 10 overs, it was swing from the hip and I was lucky to get a few out of the middle.
"I said to Tom Latham at drinks, 'I reckon we'll be all right with 320 here', and luckily we got a few more.
"Trent Boult is bowling fantastically well at the moment and Dan Vettori's catch was pretty unbelievable. The atmosphere was awesome, a step up from the England game."
"Today's 31 sixes was the highest total in a World Cup game. It's the second equal highest in a one-day international (along with NZ's 31 against India in Christchurch in 2009).
"The highest figure was 38 by India and Australia in Bangalore in 2013."
Man of the match
Man of the match Martin Guptill, who scored a record-breaking 237: "We had a couple of good partnerships early to set us up to explode at the end. We were trying to take each ball as it comes and rotate the strike. We did that well and it worked out.
"After I got 100 I thought I should hit some boundaries. Grant [Elliott] played a great little innings, as did Luke Ronchi. It was the quickest outfield I have played on here and you got value for shots.
"It was an incredible crowd. We will let this one sink in tonight and focus on the semi-finals tomorrow. It hasn't really sunk in yet. We have work to do so I can't focus on it too much."
"Today's 143-run victory by West Indies was the largest winning margin in World Cup knockout matches (in terms of runs), beating Australia's 125-run victory over India in the 2003 final in Johannesburg."
New Zealand reaction
New Zealand seamer Trent Boult (who took 4-44) on TMS: "Obviously a great performance set up by a fabulous innings from Martin Guptill. It was nice to go out and bowl well as a unit in a pretty difficult situation, they were coming out there to give it everything. Martin was hitting it clean every ball, it's something that a lot of us will be proud to look back on. I'd probably rank it the top innings I've ever seen. It's on to Auckland now and hopefully we can make some more good memories."
Man of the match
You don't need me to tell you that Martin Guptill has been named as man of the match for his unbeaten 237 from 163 balls. But I just have done.
"The whole of the Kiwi performance was excellent. Even Brendon McCullum, who missed out, played his part with his dynamic brand of captaincy."

Post update
A nice touch from the Black Caps, as while fireworks are let off around the "Cake Tin", the New Zealand fielders hang back on the 30-yard circle to allow Martin Guptill, today's hero with an unbeaten 237, to lead them off.
"It's fitting that it should be Dan Vettori should take the final wicket after his catch earlier. In the field, New Zealand were electric. West Indies made a valiant effort to keep up with the run rate, but you don't chase 390 very easily."
Champagne moment
NEW ZEALAND BEAT WEST INDIES BY 143 RUNS TO REACH WORLD CUP SEMI-FINALS

WICKET
Holder c Anderson b Vettori 42 (WI 250 all out)
Holder holes out, hoisting Vettori into the grateful hands of long-off - and New Zealand are into their seventh World Cup semi-final.
Perhaps sensing the inevitable, West Indies had even taken the batting powerplay, prompting McCullum to recall Vettori to the attack.
Holder could be on for a half-century here, the 23-year-old skipper whacking another four through mid-wicket before chipping one towards cow corner where it doesn't quite carry to the bear-like Corey Anderson sliding forward from the boundary. It would have been a spectacular catch, and we've seen a couple of those today...
Benn has a couple of big slogs and nearly chops onto his stumps with the first, before bashing a four over mid-on. He looks as though he's enjoying himself. 250 up - were West Indies only a couple of wickets down, they'd be bang on course.
"We've seen some incredible shots today from some incredible players, but no-one has hit the ball harder than Jason Holder."
Listen to TMS commentary via the audio icon.
WI 228-9 (target 394)
New Zealand turn back to the pace of Adam Milne to finish the job. A single from Holder brings last man Sulieman Benn on strike. But barring a career-defining masterclass from Big Benn, the bell will soon be tolling for West Indies.
A cross-batted swipe gets him off the mark with a single, while the similarly lanky Holder helps himself to three successive boundaries, clubbing Milne all around the park. A single takes the Windies skipper to 37 from 20 balls - he's clearly no mug with bat in hand. With the Test series in the Caribbean coming soon, England beware...
"The last rites are about to be read. Sulieman Benn isn't known for trying to occupy the crease at the best of times."
WICKET
Taylor c Guptill b Southee 11 (WI 221-9)
It only needs a quick look, and Taylor is sent on his way. The lucky catcher? None other than Martin "237 not out" Guptill.
If you're only just joining us, it's been like the other quarter-finals - entertaining, but not a very close contest as things stand. You can read all about Guptill's heroic unbeaten 237 on the BBC Sport website - while we've also had a characteristic Chris Gayle cameo at an even higher strike rate. But this game is not long for this world.
Taylor can't get Southee away for five dot balls, then New Zealand appeal for a catch at short mid-wicket. Taylor stands his ground, implying it was a bump ball. The umpires aren't sure, and send it upstairs...
WI 221-8 (Holder 23*, Taylor 11*)
World Cups are often a watershed moment, after which some players opt to call it a day on the international front. But while there have been rumours of Chris Gayle packing in Windies duty to concentrate on Twenty20 leagues (and his other duties as the self-styled "coolest man in cricket"), it would be a crying shame if this tournament is the last we see of Daniel Vettori. The wily spinner restricts the Windies to four singles.

Six
WI 217-8 (target 394)
This is already the most six-laden match in World Cup history, and after a single from Taylor, captain Holder launches Southee for another maximum over mid-wicket. A single takes the tall Bajan to 21 from 12 balls, and a remarkable Southee over goes for 16 runs - but crucially one wicket.
WI 209-8
Jerome Taylor is the new batsman, with a mere 193 more runs needed for victory. He clearly thinks the game isn't over, thumping his first two deliveries for four through the leg side.
"It's been a very watchable innings, but it's nearly done now. West Indies are facing a crushing defeat."

Russell b Southee 20 (WI 201-8)
Morning everyone... boom! Southee returns and shatters Russell's stumps. An ungainly slog across the line from Russell, whose hairstyle these days resembles that of Mr T - but unlike Mr T, he'll be getting on a plane very soon. West Indies in the World Cup departure lounge, preparing to have their passports checked.
Former West Indies fast bowler on BBC Test Match Special
"It has been an amazing tempo over the first 25 overs of an innings. The ball striking is phenomenal. They have some big hitting lower down the order but you have to look at the wickets that have fallen."
WI 201-7
This is a strange match. West Indies are going along at eight an over and yet they don't have a prayer of winning this game. Jason Holder keeps the runs flowing with a big six straight back over Vettori's head.
Time to hand you over to Mark Mitchener to guide you through to the conclusion of this match.
Corey Anderson continues. Russell prolongs the contest with an absolute murderous six over midwicket. That travelled 78 metres and it went pretty much flat. And then he repeats the dose with an extraordinary shot, chasing a wide ball outside off and getting on one foot to flat-bat it over point. Incredible batting.

WICKET
Carter b Vettori 23 (WI 173-7)
Vettori strikes! The veteran spinner draws on all his years of guile, beating Carter in the air with a lovely bit of flight and rocking back his off stump. Carter lingers at the crease in astonishment, utterly baffled to see his furniture disturbed.
Andre Russell is the new man. He will not die wondering. He butchers his second ball through mid-wicket for four.
Post update
Ian Bishop
Former West Indies fast bowler on BBC Test Match Special
"Anderson, and to a lesser extent Milne, have got a lot of wickets bowling back of a length. That was on to Sammy too quickly. Because of the run-rate, West Indies need to continue going as regularly as they can at everyone. But you need to manage the innings up to over 35, keeping wickets in hand and then see what you can build on at the end."
WICKET
Sammy c Ronchi b Anderson 27 (WI 166-6)
Sammy's entertaining innings ends in predictable fashion. Corey Anderson, a bowler with real goldenarm factor, is introduced and strikes with his first legitimate ball, forcing Sammy to mistime an attempted slog which goes miles up in the air and is caught by the keeper.
If you thought the entertainment was over when Gayle trudged off, you were wrong. Sammy has come out swinging, he lofts Boult back over his head for a lovely six. Boult responds with a bouncer which forces Sammy to hit the floor in an improvised commando roll.
"Today's match has broken the record for most sixes in a World Cup match.
"A total of 26 have been hit so far, including one on to the roof, to break the previous best of 22 set by Pakistan against Zimbabwe in 2007 and West Indies against Zimbabwe in 2015, when Chris Gayle made his 215."
WI 151-5
Daniel Vettori returns after getting an early savaging from Chris Gayle. His troubles are not at an end though. First Darren Sammy smites him over cover for four, then Carter helps himself to consecutive boundaries, slogging over midwicket for six and then driving through cover for four.
WI 134-5 (target 394)
It looks like Trent Boult is going to bowl his full allocation here. He continues for his ninth over, and once again he manages to get a grip on the spiralling run rate - just two singles from a tight over.

WI 132-5
Darren Sammy is the new man and he's off the mark in style, pulverising a drive through the covers for four. And he repeats the trick of the next ball, climbing into a full ball and smoking it to the rope. He can certainly whack it, but for how long?
"How much was that the field brought up into the circle on the on side and Gayle looking to hit on the pull into that area? He is an icon in the T20 game and brings that to the other formats. People stop ironing their underpants when Gayle comes to the crease."

WICKET
Gayle b Milne 61 (WI 120-5)
That's the key wicket. Milne's pace does for Chris Gayle, sneaking through his attempted cover drive and cannoning into the top of off stump via an inside edge. Game over?
Jonathan Carter has an important supporting role to play here. He can't afford to let the run rate slide, and he keeps the scoreboard moving with a pull through midwicket for four. Riled up, Trent Boult comes back superbly - fizzing a short ball past Carter's nose and then sliding one just past his outside edge.

RebeccaB70: So, cricket nowadays is all about the batters, bowlers don't get a look in and... what's that? Boult has four already?

Jared Maobe: It's New Zealand's day surely, How did Vettori catch Samuels' six there??? Top drawer.
"It has been a very interesting West Indian reply. They began uncertain in how they were gong to play it. They were quite defensive to try and see off the combined threat of Boult of Southee. But after losing a couple of wickets they really opened up."

Drinks break
WI 115-4
Chris Gayle isn't bothering with the off side at the moment. Milne sends down an anaemic bouncer and Gayle languidly smears it into the stands at midwicket for another six. He is in the mood tonight. Time for drinks, and do you know what, I'm really not sure if West Indies are in this game or not. It's great entertainment though.
"Chris Gayle is the first player to hit seven sixes in his first 50 runs in an ODI.
"He now has 25 in this World Cup, the most in one tournament, beating AB de Villiers' 20 (also in this World Cup).
"He currently has 36 World Cup sixes in his career, equal with AB de Villiers as the most (as at seven sixes today)."
WI 108-4 (target 394)
Trent Boult is able to put the squeeze on this burgeoning run rate by bowling a good, tight channel outside off stump. The watchful Carter blocks out six dots to give Boult his third maiden.
Leading wicket-takers in overs 1-10 in the tournament:
Trent Boult 198 balls, 120 runs, 10 wickets at 12.00 average with a rate per over of 3.63
Jerome Taylor 186 balls, 128 runs, nine wickets at 14.22 average with RPO of 4.12
Mitchell Starc 138 balls, 93 runs, seven wickets at 13.28 with RPO of 4.04
Jason Holder 198 balls, 118 runs, seven wickets at 16.85 with RPO of 3.57
50 for Gayle
WI 108-4
Brendon McCullum turns to raw pace to try and derail the steaming Gayle Express, and summons the rapid youngster Adam Milne. He keeps Gayle honest initially, but then strays too straight, allowing the batsman to flick him to fine leg for four. That brings up 50 off 26 balls for Chris Gayle - he needs to at least triple that to give West Indies a chance.
WI 101-4 (Gayle 48, Carter 8)
Jonathan Carter gets in on the act, cutting a rare bad ball from Boult past point for four to open his account. And again! This a classic West Indian stroke, high backlift, flourishing blade, driven sweetly through the covers. Runs continue to flow.
"If New Zealand don't win this World Cup then they'll never win it. If Daniel Vettori is taking one-handed catches on the boundary like Michael Jordan then this is your time."
WI 92-4
Gayle or bust now for the West Indies. He continues to make the improbable seem just about possible, flat-batting Tim Southee into the stands at square leg, then hoicking him over long-on for an absolutely enormous maximum. That went twenty rows back. Monstrous.

Ramdin lbw b Boult 0 (WI 80-4)
Trent Boult is tearing the West Indies top order apart here. Denesh Ramdin comes and goes in the blink of an eye. Good length, angling in from Boult, Ramdin is late getting his blade down and the ball cannons into his pat so hard it almost rips it off his leg. Plumb lbw, and Boult is now the leading wicket-taker in this World Cup again.
"Vettori is my favourite bowler and batsmen and now fielder. It was flying for six but he took it a good foot in the air. His reaction was so nonchalant - he put the ball on the floor as his whole team ran towards him. What a hero! Give him a knighthood, quickly!"
WICKET
Samuels c Vettori b Boult 27 (WI 80-3)
What a snag! Samuels perishes to an absolute worldy on the rope at third man, and it's Vettori, the oldest man on the pitch, who's claimed it. Samuels upper-cuts, it seems destined to fly for six, but Dan the Man leaps and plucks it nonchalantly out of the sky with one hand. The entire New Zealand team run to him. Quite brilliant.
Now Marlon Samuels joins the party! He picks up consecutive fours off Southee with a crunching drive through the covers and a clip off his toes through midwicket. Then he goes big, stepping away and lofting the bowler effortlessly into the stands at long-off.
Southee responds with a bouncer, but Samuels gets lucky and top-edges it over the keeper for another four. 'Taking Care of Business' blares out over the PA> Plenty more business to take care of yet, but this is a fine start...
Another Gayle six!
WI 59-2 (Gayle 36, Samuels 6)
Chris Gayle looks to be limping a bit, so it's stand-and-deliver from the big man. This time he climbs into Trent Boult, rocking back in the crease and bopping him back over his head for another maximum to move on to 36 off 16 balls. Then there's a huge shout off the final ball when Boult strikes Gayle on the pads. No dice from the umpire, it looked to be just sliding down leg.

Gayle three sixes in a row
WI 51-2
Here's the wily bespectacled spin king Daniel Vettori, proud possessor of the lowest economy rate at this tournament. Gayle is determined to bruise those figures though, and so far his timing is sound. He launches the tweaker for three big sixes into the stands at midwicket! This could be fun while it lasts...
ReutersCopyright: Reuters
WI 30-2 (Gayle 11, Samuels 3)
Ooh, Samuels nearly perishes first ball! A short ball hits the shoulder of the bat and loops up just over the head of the man at point. Then McCullum nearly runs out Gayle with an electric pick up and throw in the covers. West Indies are on a bed of nails at the moment.

Simmons c Guptill b Boult 12 (WI 27-2)
You can't keep Martin Guptill out of the game! Simmons carves Boult into the stands over point for a big six, but the next delivery is pushed slightly fuller and finds the edge, which is snaffled by Guppers in the cordon.
Finally West Indies find their range. Big pressure on West Indies. First Lendl Simmons smashes Southee over mid-off for four, then Gayle signals his lurking menace, flat-batting a bruising pull shot for six and then heaving over mid-on for four. That's what they need.
WI 6-1 (target 394)
New Zealand are buzzing in the field, like wasps over a dropped ice lolly. A tight over from Boult, just one from it.
Not out
WI 5-1
Well, Tim Southee was convinced but no-one else was, and for good reason it turns out. Nothing on Snicko as the ball passes the bat. A poor review, perhaps just showing how keen New Zealand are to see the back of the dangerous Gayle - he is surely the only man who can threaten this total.
Umpire review
Has Chris Gayle nicked this? New Zealand think so, but the umpire says no. We're going upstairs to sort this one out...
WI 4-1 (Gayle 1, Simmons 0)
Lendl Simmons is the new man, into the action rather earlier than he would like. He plays out four dots, which means it's a maiden for Trent Boult. Don't worry - there was a maiden in the New Zealand innings, and they scored 393.
"He looked to heave it away to make something out of these 10 overs but it's too early to do that and the bat was cleaving at empty air."

Charles b Boult 3 (WI 4-1)
Wickets in hand, yeah? Oh. New Zealand continue to dominate this match as they strike early with the ball, Trent Boult spearing in a full, swinging delivery and splattering the stumps of Johnson Charles. The swinging bat wasn't even in the same postcode.
So, a momentous task for West Indies. Chris Gayle takes strike to the first ball from Southee. So much depends on him. He's away with a single to mid-off. Johnson Charles is his partner, having replaced the walking wicket Dwayne Smith. He's off the mark with a pull to deep square leg for two.

Guptill remains in medieval mode. Russell is spanked over his head for yet another six then cut for four. In the context of what we've seen the final ball is an anti-climax as he only gets two from it. But listen to this people.

Veteran Vettori fancies a piece of the action here. Two balls, two boundaries, the second via a huge stroke of luck as a huge inside edge whistles through his legs, past his off stumps and away to the rope.

I'm told Guptill's second hundred came off 41 balls. That beggars belief. And, incredibly, it only takes him three more blows to motor past Gayle. Six - four - four and it's the highest score in World Cup history. Chris Gayle walks over to shake his hand. Lovely moment.

"Stand up New Zealand, stand up the world. Just glorious."

Guptill 200
Guptill wastes no time in becoming the first New Zealander to make an ODI double hundred. And he gets there in style with a blistering drive down the ground for four. The crowd erupts. Guptill salutes. Other-worldly indeed.
"It's going to take something special for West Indies to even get close to this, but they do have a couple of players capable of other-worldly batting."
"The highest World Cup knockout total is Australia's 359-2 v India at Johannesburg in the 2003 final."
NZ 339-5 (Guptill 199, Ronchi 1)
Ronchi gets off the mark with a single to long-on. Guptill has had his breather. And he gets straight back to business with a blistering drive over the bowler's head that lands just inside the boundary. Two away from a double ton. He pulls it hard, but it's only one. 199 not out and on strike.
"I've been impressed with the way Guptill has gone through periods of difficulty in this innings. He's played some deft little cuts when there's been not a lot of pace on the ball, and now he's broadened his range of strokes. It's been a complete innings."
"Bowling in overs 41-50 in this World Cup to date, Jason Holder has conceded 118 runs in 5 overs (as at end of 45th over today)."
NZ 328-4
Can Guptill beat Gayle's 215 and set a new record for the highest World Cup score? That's the big question. Mind you, it's Grant Elliott who is tucking in right now. Back to back sixes to bring up the 50 partnership off 15 balls in 13 minutes!!

"Jason Holder is one of the bravest men I know. I've seen him go all around the park in the death overs, AB de Villiers ripped him to pieces at the SCG, but he still stands up and does it. It's an absolute run-fest, Martin Guptill's on fire."

Three sixes! NZ 309-4
Guptill only needs a single swipe to put his name in the record books as he launches Holder for another six. But that's just for starters. Two more enormous sixes follow to take New Zealand past 300.
In between, there are calls for a taxi for Johnson Charles when he misfields terribly to gift Elliot a four. It's 27 runs from the over. Another horror show from Holder.

Different bowler, same deal. Guptill's combination of timing and power is breathtaking as he pummels Holder for a six over mid-off then pulls a full toss away for another maximum. The double ton is a real possibility here.

Taylor run out 42 (NZ 232-3)
Guptill goes for the sweep but can't connect. Taylor sets off and is halfway down the track when Guptill sends him back. The throw to Benn is fast and accurate and the bowler whips off the bails. It's a wicket but probably not the man the Windies wanted.

Guppers is putting his foot down here. The arrival of Taylor's pace is no skin of his nose as he cracks him between long-on and deep midwicket for four then launches a slower ball over square leg for six. The last ball is fast and full but Guptill is seeing it so early and simply lashes back over the bowler's head for four more.

This is starting to look a bit messy from a Windies perspective. Guptill picks up two boundaries off Benn via a sweep and a lovely late cut.

100 partnership - NZ 200-2
Too short from Sammy and Taylor cuts his second boundary past point for four to bring up the 100 partnership. It's the fifth between this pair in ODIs.
Is this one over too many for Sammy? Looks like it as Guptill launches him over mid-on into the stands about 30 rows back. That's the 401st six of the tournament and quite possibly one of the biggest.

Guptill is within one blow of a ton. The crowd clap in anticipation. A dab to third man gets him two to reach 99. Oohs and aahs. The next ball is caressed down the ground for a single and he's there. A huge roar echoes round the Cake Tin. Superb innings from the Kiwi frontman. Taylor rounds off the over with his first boundary to ensure the ensuing drinks will taste all the sweeter.
"New Zealand are still scoring at a comfortable rate. They have the likes of Elliott, Anderson and Ronchi to come, all free strikers who they can use in the last 20 overs. The launchpad is there."
NZ 175-2 (Guptill 95, Taylor 29)
Samuels to Guptill - four down the ground. He is closing in on back-to-back World Cup hundreds here.

Six balls. Six singles. Guptill is really quick off the mark for a big man. Always on his toes. It strikes me that some batsmen simply expect to score off every ball. Steve Smith is another - he scored at a run a ball yesterday without playing a shot in anger.

West Indies just haven't been able to keep New Zealand under the pump when they've taken wickets, the Black Caps have been able to bed in new partnerships without letting the run rate drop drastically. They'll have 300 in their sights here. Sulieman Benn prevents four with a rather old-school piece of fielding, footballing the ball back inside the rope.

Michael from Edinburgh, on holiday in Western Australia: Teams are abusing the DRS. It is meant to be for howlers. Benn today and Finch yesterday both gambled away their sides reviews.

NZ 130-2
Another new bowler for New Zealand to get to grips with, it's the off-spin of Marlon Samuels. Will New Zealand stick or twist against the part-timer? He begins with a loosener, down the leg side and tickled fine by Guptill for two. Samuels strays again, short and wide outside off and this time Guptill doubles the dose, backing away and lacing him through point for four.

NZ 121-2 (Guptill 61, Taylor 11)
Darren Sammy is into the attack for the West Indies. He'll send down some nagging military medium. No need for the New Zealand batsmen to risk a big shot after that productive last over, and indeed they just keep the scoreboard with four nudged singles.
"It's been quite a productive period for the West Indies. New Zealand have only scored 4.2 runs per over from the last set of 10 so the Windies have restricted them a little bit and taken the wicket of Williamson. They haven't lost control of this game."

The West Indies are content to allow the batsmen to milk singles off the spin of Benn, but it's a dangerous game to play.

We're seeing a few more defensive strokes from New Zealand now after that all-action start. These two batsmen have been slightly under the microscope in recent times - they will be desperate to go big here.

Now, can Andre Russell keep the pressure on? He begins with a short ball that Williamson pulls for a single to the boundary-rider at midwicket. Martin Guptill has just got a little bogged down here - two accurate deliveries from Russell extend his run of scoreless deliveries to eight before he steals a single with a drop-and-run defensive stroke.
Two more singles round out the over as New Zealand perhaps reset their sights to the goal of steady, risk-free accumulation. West Indies have come back well in he last few overs.

Another bowling change as Andre Russell, owner of the funkiest haircut as this World Cup, gets a bowl. New Zealand are getting a boundary off every over at the moment, they are so adept at keeping the run rate up at parts of the innings when other sides retreat into their shell. This time Williamson seizes on a toothless short ball and pulls it powerfully through midwicket.
"Just think next week, India v Australia. That will be the most popular India side ever to take the field. Pakistanis and Bangladeshis might be supporting Australia but everyone else will be rooting for India."
NZ 71-1
Benn continues, with a little more insurance now that the powerplay is over and he can have a few more fielders on the rope. No point having insurance when you bowl it there though, full toss outside off and Guptill gets it past the man on the boundary at deep cover. New Zealand motoring here.

Holder continues from the other end - will we see him bowl his set of ten straight through like he did in the previous match against UAE? Kane Williamson is a short man but he has a great ability to ride the bounce of the ball off the back foot, and he picks up four with a lovely cut shot past point.

An early introduction for the spin of Sulieman Benn. He starts badly, too short and Guptill pounces on it, rolling the wrists on it and flaying it past point for four. The batsmen exchange singles from the remaining deliveries to keep the run rate hovering healthily just above a run a ball.

Jason Holder has bowled a really nice length so far, just a little shorter than Taylor, making it much harder for the batsmen to drive him down the ground. He builds a little bit of pressure on Martin Guptill with four dot balls, but the batsman gets away off the fifth delivery, hitting a drive into the ground that bounces over the covers and brings three.
"West Indies are trying to bowl quite full, allowing the ball to move. There will be two people in this ground who will be very happy to see the ball moving in the air: Trent Boult and Tim Southee. They know they can wreak havoc if it's swinging."

The 'V' is proving a very productive scoring zone for New Zealand so far. Once again Jerome Taylor sees the ball whistle back past his toes as this time Kane Williamson meets a full delivery with the face of the bat.

McCullum c Holder b Taylor 12 (NZ 27-1)
Silly, silly, silly. McCullum's inability to take a backward step has cost him here. He tries to blast Jerome Taylor into the stands but doesn't time it at all, the ball slices up in the air towards deep cover, where Jason Holder extends his long tentacles to reel in an absolute blinder of a catch. One captain removes the other.
Brendon McCullum has been muffled so far - he's only seen one ball of the first three overs.
Now he gets his chance to eye up Jason Holder and immediately signals his intent. He advances down the track and a mistimed swipe is stopped at mid-on, but he doesn't miss out on the next two. First he whips a leg-side delivery off his pads for four, then he picks up a short ball and swats it into the stands!
Better yet, it's caught one-handed by a gentleman in the crowd, who wins a share of the million-dollar jackpot.

Martin Guptill is in no mood to hang around.

The ball is swinging early on for the Windies seamers. Captain Jason Holder takes the new nut at the other end. Sharp running is a feature of the New Zealand batting effort, and after ten balls, Guptill finally rotates the strike with a quick scampered single to allow Brendon McCullum to get in on the act.
McCullum repeats the trick off his first delivery, dropping the ball at his feet and setting off like a hare to beat the throw at the non-striker's end.
"By choosing to bat, I think McCullum is saying that in these types of games runs on the board matter more. Now they have to go on and post a decent total. They have been fallible in the past. Their batting hasn't been thoroughly reliable. There is always a bit of jitteriness. They have to play well from now on."
NZ 5-0
Well well, what a let off for New Zealand early on. Guptill connected sweetly but couldn't keep the stroke down and it should have been pouched.

Time for the anthems. New Zealand giving it the full arms-around-the-shoulders treatment as they belt out 'God Defend New Zealand'. West Indies looking rather more mellow - shades on to a man.

"This is a massive game for New Zealand. They've won six on the bounce but now it's all knockout that all goes out the window. It's easy to roll through the group stages but all of a sudden one false move, one big knock from Chris Gayle and the Windies could take it all away from them."

Hold on to your hats...
This opening period could be very tasty. Here's why...
New Zealand have by far the best run rate of any team in the tournament in the opening ten overs, averaging well over 7 runs per over.
But West Indies bowlers have taken the most wickets within the first 10 overs of the innings in this WC: 15.
Post update
Stephan Shemilt
BBC Sport in Wellington
"This feels big. Throughout, it has felt as if this tournament has meant more in New Zealand and, in contrast to the half-empty Adelaide to watch Australia yesterday, the Cake Tin in Wellington is set to be sold out.
"Fans are streaming towards the ground along a vast concrete entrance, not unlike Wembley way. The New Zealand team bus even needed a police escort."
A tale of two captains
One of the most intriguing and potentially decisive subplots in this match involves the respective captains.
In the black corner, Brendon McCullum, a man widely regarded as the best skipper in world cricket. Audacious, talismanic and relentlessly aggressive, McCullum has been the driving force behind New Zealand's transformation from declining also-rans to rising stars of world cricket.
What a contrast between the ultra-experienced Kiwi skipper and the callow West Indies captain Jason Holder. Just 23 years old, the Barbadian has occasionally seemed a man out of his depth in this tournament as he tries to band together a seemingly dissolute side of big hitters and big egos.
However, the Windies captain has been very impressive with the ball - he could have a key role to play early doors today.

Home comforts
New Zealand have won the last two World Cup matches between these sides in 2003 and 2007, and moreover, they have emerged victorious in all three ODIs played between these sides at this stadium.
The Westpac Stadium is a particularly happy hunting ground for pace bowler Tim Southee, who has taken 21 wickets at 12.00 in 6 ODIs at this venue.
Not only that, seven of the last eight completed ODIs between these sides have been won by the side batting first.
Gayle blows back into town
So, Chris Gayle is fit and raring to go. It is undoubtedly a boost to the Windies, but how does New Zealand captain Brendon McCullum feel about it? Not bad, actually...
"I don't think it changes things too much because we expected him to play anyway. He's obviously a world-class player and destructive on his day. The West Indies team are stacked with match-winners, not just Chris but many other guys in their line-up."

Team news
Both teams shuffle their pack. The headline news is that talismanic opener Chris Gayle is fit and plays for the West Indies - he replaces Dwayne Smith. Sulieman Benn comes in for Kemar Roach to provide a specialist spin option. For New Zealand, Adam Milne replaces Mitchell McClenaghan as the third seamer.
New Zealand XI: Martin Guptill, Brendon McCullum (capt), Kane Williamson, Ross Taylor, Grant Elliott, Corey Anderson, Luke Ronchi (wk), Daniel Vettori, Adam Milne, Tim Southee, Trent Boult.
West Indies XI: Chris Gayle, Johnson Charles, Lendl Simmons, Marlon Samuels, Denesh Ramdin (wk), Jonathan Carter, Darren Sammy, Andre Russell, Jason Holder (capt), Jerome Taylor, Sulieman Benn.
Toss
New Zealand win the toss and captain Brendon McCullum elects to bat first.
"The wicket looks good," he says. "It looks a bit different from the wicket we played England on. Runs on the board can be quite valuable in this sort of situation and hopefully we can get a few on the board."
West Indies captain Jason Holder says he's not too disappointed. "We're very confident coming into this game," he says. "There's a lot of pressure on New Zealand in their home town."

Hello
Welcome one and all to our coverage of the final quarter-final of the Cricket World Cup. It's New Zealand v West Indies in Wellington, for a place in the semi-finals against South Africa. Here comes the news from the toss...
No surprises?
So far, so predictable. After the hurly-burly of the group stage, which saw Ireland stun West Indies and Bangladesh upset England, the knockout stages of the Cricket World Cup have so far proved surprise-free.
Three quarter-final matches, three wins for the favourites, and if we're being honest, not a close game among them.
On paper, tonight's last quarter-final should be the most predictable of the lot. After all, West Indies were well below their best in the group stages, losing to Ireland and suffering an absolute hammering against South Africa. New Zealand, on the other hand, were superb, sweeping all before them to win six matches out of six.
With the Black Caps enjoying home advantage, they will be heavy favourites. But with the West Indies, you never quite know what to expect...

As TMS fades from the airwaves, it's time to wave goodbye to the quarter-finals - and to Sri Lanka, Bangladesh, Pakistan and West Indies. Four titans remain: New Zealand, South Africa, Australia and India.
The semi-finals start on Tuesday - but if your cricket appetite can't wait until then, from tomorrow you can listen to the Champion County game between MCC and Yorkshire from Abu Dhabi. A trio of once (and future?) England openers head the MCC batting order: Messrs Cook, Compton and Carberry.
But make sure you join us on Tuesday morning - NZ v SA gets under way at 01:00 GMT, we'll be here from 00:30. Until then, enjoy a bumper weekend of sport and raise a glass to an astonishing performance from Martin Guptill. TTFN.

Graeme Swann
Ex-England spinner on BBC Test Match Special
"Phil Simmons coming in as coach should unite the West Indies, he's done a very good job with Ireland."
Review of the day
If your alarm clock has just gone off and awoken you for the start of a special Saturday of sport, I'm afraid it's all over down under where it'll be the Kiwis dancing on the streets of Wellington tonight.
Martin Guptill led the way with an astonishing unbeaten 237 at the top of the order as they posted 393-6, and although Chris Gayle (61), rendered largely immobile by injury, got West Indies off to a flier of sorts - indeed, the Caribbean men hit more sixes than the Kiwis - once he departed at 120-5, the game was up for them.
Captain's view
New Zealand captain Brendon McCullum on Daniel Vettori's one-handed catch: "I gave him no chance to be honest,. You saw the reaction of the boys to run from all corners to celebrate. He us a legend of New Zealand cricket, a special man and a cricketer and you can see what his involvement means to us."

Louis Strong: NZ, India, South Africa and Aussies. The best four ODI teams. England had no chance so I don't know why we were surprised.
Captain's view
More from New Zealand captain Brendon McCullum: "The way our team is structured it allows us a licence at the start. For us to be competitive on a regular basis we need to play an attacking style of cricket. We will continue to play like that.
"We know how dangerous the West Indies players are. They are clean strikers. We wanted to make a statement and make it a professional performance across the board. The bowlers made sure we did that. It is great to progress, we will celebrate tonight and then turn our attention to Auckland. We will do our homework and put our best foot forward."
Post update
Graeme Swann
Ex-England spinner on BBC Test Match Special
"Guptill's first 100 runs were very classically scored. He played some beautiful straight drives, and didn't take may risks. His hundred was perfectly timed, and he went mental from that point onwards. It was incredible to watch."
Captain's view
New Zealand captain Brendon McCullum on TMS: "That was the greatest innings in ODIs I've ever seen live, the skills that Martin Guptill displayed were once in a lifetime really. Everyone here will remember it for the rest of their lives.
"I'm still trying to work out how we got 394, it's a mammoth score. We knew that they had ball strikers, but the bowlers hung tough under pressure. Dan Vettori wasn't at his miserly best today, but he created opportunities. Trent Boult just gets better and better."
Captain's view
More from West Indies captain Jason Holder: "It was a tough to defend. We were in the game until the 35th over. Guptill played superbly. We dropped him early and it cost us. The ball sat up well on the pitch and he could put it where he wanted.
"It has been a challenge. I had high hopes coming into it, but it has been a rollercoaster. We have learned a lot. It is about learning as quickly as possible. We need to find out where he went wrong and assess what we do.
"I would like to keep the captain's job. It is something I have always wanted to do and I don't think I have done too badly. I would like to thank the supporters who came here to help us."
Bridesmaids again?
New Zealand have often been the bridesmaids of international cricket - reaching World Cup semi-finals in (deep breath) 1975, 1979, 1992, 1999, 2007 and 2011 - but never a final. Can they go the distance this time in 2015?
It should be noted, unlike England, they have won a 50-over ICC global event - triumphing in the ICC Knock-Out (the forerunner of the modern Champions Trophy) in Kenya in 2000.
Their semi-final opponents South Africa have a not dissimilar record - three times World Cup semi-finalists, never a finalist, and won the inaugural ICC Knock Out in 1998.
Riaz and Watson fined
A snippet of news from yesterday's game: Pakistan fast bowler Wahab Riaz was fined 50% of his match fee while Australia all-rounder Shane Watson was penalised 15% of his after their angry clash in Friday's World Cup quarter-final.
Riaz was charged with using obscene language, while Watson was accused of conduct contrary to the spirit of the game when the two faced each other down in a compelling passage of play during Australia's six-wicket win at the Adelaide Oval.
ICC match referee Ranjan Madugalle said: "It was an enthralling contest between Shane and Wahab, but in the closing stages both players crossed that fine line between intense competition and unacceptable behaviour."
Captain's view
West Indies captain Jason Holder on TMS: "It's quite disappointing, we came into this game with high hopes. Martin Guptill took the game away from us with his 200 and we didn't bowl well in the death overs. 393 is a big score but it was a good wicket and I thought we could have put up a better fight.
"I hope it's not the end of Chris Gayle's international career but that's up to Chris. We've been away from home for a long time and so many guys are mentally and physically tired. We'll have a well-deserved rest before the Test series against England."

Jeremy Coney
Ex-New Zealand captain on BBC Test Match Special
"Martin Guptill dazzled. He turned this stadium into a little carnival. He hit the ball so cleanly, drives that you've never seen anything like. He thoroughly deserves all the accolades he's getting."
Post update
Guptill also admitted he didn't think he'd ever surpass the 189 not out he made from 155 balls against England in Southampton in 2013. I was at that game and it was a phenomenal innings, but today's knock was on another level entirely.
(Historians may also note that the aforementioned 2013 game also saw the last ODI outing in England colours for Jade Dernbach, who was flogged around Hampshire for 87 runs in 10 overs).
Man of the match
More from Martin Guptill on TMS: "It hasn't quite sunk in, but the boys will have a few drinks tonight and I'll probably hear all about it. Last 10 overs, it was swing from the hip and I was lucky to get a few out of the middle.
"I said to Tom Latham at drinks, 'I reckon we'll be all right with 320 here', and luckily we got a few more.
"Trent Boult is bowling fantastically well at the moment and Dan Vettori's catch was pretty unbelievable. The atmosphere was awesome, a step up from the England game."
How's stat?
Andrew Samson
BBC Test Match Special statistician
"Today's 31 sixes was the highest total in a World Cup game. It's the second equal highest in a one-day international (along with NZ's 31 against India in Christchurch in 2009).
"The highest figure was 38 by India and Australia in Bangalore in 2013."
Man of the match
Man of the match Martin Guptill, who scored a record-breaking 237: "We had a couple of good partnerships early to set us up to explode at the end. We were trying to take each ball as it comes and rotate the strike. We did that well and it worked out.
"After I got 100 I thought I should hit some boundaries. Grant [Elliott] played a great little innings, as did Luke Ronchi. It was the quickest outfield I have played on here and you got value for shots.
"It was an incredible crowd. We will let this one sink in tonight and focus on the semi-finals tomorrow. It hasn't really sunk in yet. We have work to do so I can't focus on it too much."
How's stat?
Andrew Samson
BBC Test Match Special statistician
"Today's 143-run victory by West Indies was the largest winning margin in World Cup knockout matches (in terms of runs), beating Australia's 125-run victory over India in the 2003 final in Johannesburg."
New Zealand reaction
New Zealand seamer Trent Boult (who took 4-44) on TMS: "Obviously a great performance set up by a fabulous innings from Martin Guptill. It was nice to go out and bowl well as a unit in a pretty difficult situation, they were coming out there to give it everything. Martin was hitting it clean every ball, it's something that a lot of us will be proud to look back on. I'd probably rank it the top innings I've ever seen. It's on to Auckland now and hopefully we can make some more good memories."
Man of the match
You don't need me to tell you that Martin Guptill has been named as man of the match for his unbeaten 237 from 163 balls. But I just have done.

Close!
WI 250-9
Holder could be on for a half-century here, the 23-year-old skipper whacking another four through mid-wicket before chipping one towards cow corner where it doesn't quite carry to the bear-like Corey Anderson sliding forward from the boundary. It would have been a spectacular catch, and we've seen a couple of those today...
Benn has a couple of big slogs and nearly chops onto his stumps with the first, before bashing a four over mid-on. He looks as though he's enjoying himself. 250 up - were West Indies only a couple of wickets down, they'd be bang on course.

"We've seen some incredible shots today from some incredible players, but no-one has hit the ball harder than Jason Holder."
Listen to TMS commentary via the audio icon.
WI 228-9 (target 394)
New Zealand turn back to the pace of Adam Milne to finish the job. A single from Holder brings last man Sulieman Benn on strike. But barring a career-defining masterclass from Big Benn, the bell will soon be tolling for West Indies.
A cross-batted swipe gets him off the mark with a single, while the similarly lanky Holder helps himself to three successive boundaries, clubbing Milne all around the park. A single takes the Windies skipper to 37 from 20 balls - he's clearly no mug with bat in hand. With the Test series in the Caribbean coming soon, England beware...

WICKET
Taylor c Guptill b Southee 11 (WI 221-9)
It only needs a quick look, and Taylor is sent on his way. The lucky catcher? None other than Martin "237 not out" Guptill.
If you're only just joining us, it's been like the other quarter-finals - entertaining, but not a very close contest as things stand. You can read all about Guptill's heroic unbeaten 237 on the BBC Sport website - while we've also had a characteristic Chris Gayle cameo at an even higher strike rate. But this game is not long for this world.
Scorecard
Third umpire
WI 221-8
Taylor can't get Southee away for five dot balls, then New Zealand appeal for a catch at short mid-wicket. Taylor stands his ground, implying it was a bump ball. The umpires aren't sure, and send it upstairs...
WI 221-8 (Holder 23*, Taylor 11*)
World Cups are often a watershed moment, after which some players opt to call it a day on the international front. But while there have been rumours of Chris Gayle packing in Windies duty to concentrate on Twenty20 leagues (and his other duties as the self-styled "coolest man in cricket"), it would be a crying shame if this tournament is the last we see of Daniel Vettori. The wily spinner restricts the Windies to four singles.

Six
WI 217-8 (target 394)
This is already the most six-laden match in World Cup history, and after a single from Taylor, captain Holder launches Southee for another maximum over mid-wicket. A single takes the tall Bajan to 21 from 12 balls, and a remarkable Southee over goes for 16 runs - but crucially one wicket.
WI 209-8
Jerome Taylor is the new batsman, with a mere 193 more runs needed for victory. He clearly thinks the game isn't over, thumping his first two deliveries for four through the leg side.

"It has been an amazing tempo over the first 25 overs of an innings. The ball striking is phenomenal. They have some big hitting lower down the order but you have to look at the wickets that have fallen."
WI 201-7
This is a strange match. West Indies are going along at eight an over and yet they don't have a prayer of winning this game. Jason Holder keeps the runs flowing with a big six straight back over Vettori's head.
Time to hand you over to Mark Mitchener to guide you through to the conclusion of this match.
Reaction to Guptill's 237*
Former New Zealand all-rounder Scott Styris: Wellington have been spoilt!! First Southee vs England now Guptill vs WI
David 'Bumble' Lloyd: Just woke up ......what ?????? Martin Guptill 237 !!!!!!! Well played !!!
Former Liverpool midfielder Dietmar Hamann: What a knock by Guptill. Great call to stick with him when he couldn't buy a run before the World Cup.
WI 191-7 (Russell 18, Holder 6)
Corey Anderson continues. Russell prolongs the contest with an absolute murderous six over midwicket. That travelled 78 metres and it went pretty much flat. And then he repeats the dose with an extraordinary shot, chasing a wide ball outside off and getting on one foot to flat-bat it over point. Incredible batting.

Carter b Vettori 23 (WI 173-7)
Vettori strikes! The veteran spinner draws on all his years of guile, beating Carter in the air with a lovely bit of flight and rocking back his off stump. Carter lingers at the crease in astonishment, utterly baffled to see his furniture disturbed.
Stick a fork in West Indies - they're done.

"Anderson, and to a lesser extent Milne, have got a lot of wickets bowling back of a length. That was on to Sammy too quickly. Because of the run-rate, West Indies need to continue going as regularly as they can at everyone. But you need to manage the innings up to over 35, keeping wickets in hand and then see what you can build on at the end."
WICKET
Sammy c Ronchi b Anderson 27 (WI 166-6)
Sammy's entertaining innings ends in predictable fashion. Corey Anderson, a bowler with real goldenarm factor, is introduced and strikes with his first legitimate ball, forcing Sammy to mistime an attempted slog which goes miles up in the air and is caught by the keeper.

"A total of 26 have been hit so far, including one on to the roof, to break the previous best of 22 set by Pakistan against Zimbabwe in 2007 and West Indies against Zimbabwe in 2015, when Chris Gayle made his 215."
WI 151-5
Daniel Vettori returns after getting an early savaging from Chris Gayle. His troubles are not at an end though. First Darren Sammy smites him over cover for four, then Carter helps himself to consecutive boundaries, slogging over midwicket for six and then driving through cover for four.
WI 134-5 (target 394)
It looks like Trent Boult is going to bowl his full allocation here. He continues for his ninth over, and once again he manages to get a grip on the spiralling run rate - just two singles from a tight over.
In case you missed it...
WI 132-5
Darren Sammy is the new man and he's off the mark in style, pulverising a drive through the covers for four. And he repeats the trick of the next ball, climbing into a full ball and smoking it to the rope. He can certainly whack it, but for how long?

Scorecard
WI 120-4 (Gayle 61, Carter 13)
Jonathan Carter has an important supporting role to play here. He can't afford to let the run rate slide, and he keeps the scoreboard moving with a pull through midwicket for four. Riled up, Trent Boult comes back superbly - fizzing a short ball past Carter's nose and then sliding one just past his outside edge.

Drinks break
WI 115-4
Chris Gayle isn't bothering with the off side at the moment. Milne sends down an anaemic bouncer and Gayle languidly smears it into the stands at midwicket for another six. He is in the mood tonight. Time for drinks, and do you know what, I'm really not sure if West Indies are in this game or not. It's great entertainment though.

50 for Gayle
WI 108-4
Brendon McCullum turns to raw pace to try and derail the steaming Gayle Express, and summons the rapid youngster Adam Milne. He keeps Gayle honest initially, but then strays too straight, allowing the batsman to flick him to fine leg for four. That brings up 50 off 26 balls for Chris Gayle - he needs to at least triple that to give West Indies a chance.
WI 101-4 (Gayle 48, Carter 8)
Jonathan Carter gets in on the act, cutting a rare bad ball from Boult past point for four to open his account. And again! This a classic West Indian stroke, high backlift, flourishing blade, driven sweetly through the covers. Runs continue to flow.

Samuels c Vettori b Boult 27 (WI 80-3)
What a snag! Samuels perishes to an absolute worldy on the rope at third man, and it's Vettori, the oldest man on the pitch, who's claimed it. Samuels upper-cuts, it seems destined to fly for six, but Dan the Man leaps and plucks it nonchalantly out of the sky with one hand. The entire New Zealand team run to him. Quite brilliant.
Scorecard
WI 80-2
Now Marlon Samuels joins the party! He picks up consecutive fours off Southee with a crunching drive through the covers and a clip off his toes through midwicket. Then he goes big, stepping away and lofting the bowler effortlessly into the stands at long-off.
Southee responds with a bouncer, but Samuels gets lucky and top-edges it over the keeper for another four. 'Taking Care of Business' blares out over the PA> Plenty more business to take care of yet, but this is a fine start...
Another Gayle six!
WI 59-2 (Gayle 36, Samuels 6)
Chris Gayle looks to be limping a bit, so it's stand-and-deliver from the big man. This time he climbs into Trent Boult, rocking back in the crease and bopping him back over his head for another maximum to move on to 36 off 16 balls. Then there's a huge shout off the final ball when Boult strikes Gayle on the pads. No dice from the umpire, it looked to be just sliding down leg.
Gayle three sixes in a row
WI 51-2
Here's the wily bespectacled spin king Daniel Vettori, proud possessor of the lowest economy rate at this tournament. Gayle is determined to bruise those figures though, and so far his timing is sound. He launches the tweaker for three big sixes into the stands at midwicket! This could be fun while it lasts...
WI 30-2 (Gayle 11, Samuels 3)
Ooh, Samuels nearly perishes first ball! A short ball hits the shoulder of the bat and loops up just over the head of the man at point. Then McCullum nearly runs out Gayle with an electric pick up and throw in the covers. West Indies are on a bed of nails at the moment.
WICKET
Simmons c Guptill b Boult 12 (WI 27-2)
You can't keep Martin Guptill out of the game! Simmons carves Boult into the stands over point for a big six, but the next delivery is pushed slightly fuller and finds the edge, which is snaffled by Guppers in the cordon.
Scorecard
Six
WI 21-1
Finally West Indies find their range. Big pressure on West Indies. First Lendl Simmons smashes Southee over mid-off for four, then Gayle signals his lurking menace, flat-batting a bruising pull shot for six and then heaving over mid-on for four. That's what they need.
WI 6-1 (target 394)
New Zealand are buzzing in the field, like wasps over a dropped ice lolly. A tight over from Boult, just one from it.
Not out
WI 5-1
Well, Tim Southee was convinced but no-one else was, and for good reason it turns out. Nothing on Snicko as the ball passes the bat. A poor review, perhaps just showing how keen New Zealand are to see the back of the dangerous Gayle - he is surely the only man who can threaten this total.
Umpire review
Has Chris Gayle nicked this? New Zealand think so, but the umpire says no. We're going upstairs to sort this one out...
WI 4-1 (Gayle 1, Simmons 0)
Lendl Simmons is the new man, into the action rather earlier than he would like. He plays out four dots, which means it's a maiden for Trent Boult. Don't worry - there was a maiden in the New Zealand innings, and they scored 393.

So, a momentous task for West Indies. Chris Gayle takes strike to the first ball from Southee. So much depends on him. He's away with a single to mid-off. Johnson Charles is his partner, having replaced the walking wicket Dwayne Smith. He's off the mark with a pull to deep square leg for two.

Guppers is putting his foot down here.

NZ 160-2 (Guptill 86, Taylor 24)
Sammy had been very expensive in this tournament up until now but he's bowling a really good, tight spell here. Oh, just as I write that he strays on to leg stump allowing Guptill to whip a four through midwicket. That's the first boundary for 43 balls.

Navaneeth BK: Time for NZ to prove they are more than just a Captain Fantastic team, look like they are doing it.
NZ 155-2
Guptill opens to face to work Samuels down to third man for three runs. No sign of genuine pace being brought back in yet. Sammy to resume.

"In case you're wondering why it's called the Cake Tin, the ground looks like, erm, a Cake Tin. Silly/brilliant name aside, it is positioned in a stunning waterside setting, surely one of the closest international cricket grounds to the sea.
"At the very tip of New Zealand's north island, we're surrounded by green hills and mountains that peer over the stands. The sun has now moved round enough for almost the entire playing surface to be bathed in warmth. Lovely stuff."
NZ 149-2 (Guptill 78, Taylor 22)
This is old-fashioned middle overs stuff, but the run rate is 5.32 so NZ remain perfectly placed here. Not many more bowling options for captain Holder. Perhaps worth giving one of the quicks a short spell to try to break this stand.

"We've seen a bit of turn for the spinners but not much. I think New Zealand will only use Williamson later on if they notice that Vettori is getting some purchase."
NZ 146-2
Six balls. Six singles. Guptill is really quick off the mark for a big man. Always on his toes. It strikes me that some batsmen simply expect to score off every ball. Steve Smith is another - he scored at a run a ball yesterday without playing a shot in anger.
Guptill is known as 'Two Toes' within the New Zealand team as he lost three digits on one foot when he was 14. In a forklift truck accident, obviously.
NZ 140-2
Thanks James. Greetings all. New Zealand look set for a big one here. Let's just hope that whatever happens the Windies manage to make a game of this. Wickets in hand. That will be the key because they have plenty of power lower down the order.
Good over from Sammy, with just a single a piece to the not out batters, with Taylor pushing past cover to pinch the strike.
NZ 138-2
Ross Taylor is beginning to find his confidence here after a sticky start, lap-sweeping Samuels for two behind square. New Zealand are well placed at the halfway mark, but a couple of wickets could drag the West Indies right back into this match.
Time to hand you over to Sam Sheringham for the remainder of the New Zealand innings.
NZ 135-2 (Guptill 71, Taylor 15)
West Indies just haven't been able to keep New Zealand under the pump when they've taken wickets, the Black Caps have been able to bed in new partnerships without letting the run rate drop drastically. They'll have 300 in their sights here. Sulieman Benn prevents four with a rather old-school piece of fielding, footballing the ball back inside the rope.

Michael from Edinburgh, on holiday in Western Australia: Teams are abusing the DRS. It is meant to be for howlers. Benn today and Finch yesterday both gambled away their sides reviews. Are we going to see a match, maybe the final, decided in the dying moments by a howler only for the team on the receiving end having gambled away their review?
NZ 130-2
Another new bowler for New Zealand to get to grips with, it's the off-spin of Marlon Samuels. Will New Zealand stick or twist against the part-timer? He begins with a loosener, down the leg side and tickled fine by Guptill for two. Samuels strays again, short and wide outside off and this time Guptill doubles the dose, backing away and lacing him through point for four.

"Have New Zealand been looking a touch nervous? One question throughout the tournament has been if they can get enough runs when McCullum and Williamson don't do the business. We're about to find out. Mind you, Martin Guptill, off the back of a ton, has looked the part, driving the seamers and cutting Sulieman Benn."
NZ 121-2 (Guptill 61, Taylor 11)
Darren Sammy is into the attack for the West Indies. He'll send down some nagging military medium. No need for the New Zealand batsmen to risk a big shot after that productive last over, and indeed they just keep the scoreboard with four nudged singles.

Jeremy Coney
Ex-New Zealand captain on BBC Test Match Special
"It's been quite a productive period for the West Indies. New Zealand have only scored 4.2 runs per over from the last set of 10 so the Windies have restricted them a little bit and taken the wicket of Williamson. They haven't lost control of this game."

NZ 117-2
Sulieman Benn has dragged things back well for West Indies but he's starting to lose control again here. He gets too straight and the Kiwi batsmen punish him. First Guptill sweeps him for four, then Taylor nudges him fine for three. Guptill rounds out a big over, smashing a short ball to the fence at point for another four. 12 of the over.

"It's a good knock but it assumes so much more importance now that Williamson has gone. But he has only done 40% of his job. He needs to be there at over 46 or 47 because if he does that he will have 120 or 140 to his name."
50 for Guptill
NZ 105-2 (run rate 5.25)
Russell continues. Taylor is taking his time here, he has been short of his usual fluency recently and he's keenly aware of the importance of this knock. He eats up four dots before working a single, then Guptill goes to his third consecutive fifty with a nudge to third man. A good knock - can he go to a ton and anchor a big score for New Zealand here?
NZ 103-2
The West Indies are content to allow the batsmen to milk singles off the spin of Benn, but it's a dangerous game to play. The hitherto accurate twirler throws in a shocker of a final ball, short and wide and Guptill cuts him away to the point boundary, turning an average over into a very good one. Eight from it.
NZ 95-2 (Guptill 43, Taylor 3)
We're seeing a few more defensive strokes from New Zealand now after that all-action start. These two batsmen have been slightly under the microscope in recent times - they will be desperate to go big here.
Comedy capers off the final ball as the Windies try to catch Guptill wandering out of his crease with a sharp throw, but he's home safe and the ball rebounds off the stumps to gift New Zealand an extra run. Four off the over.

"The home crowd is living every moment of this - the huge cheer when Williamson survived that review, the gasp when he contrived to slap a half-tracker to cover. For the first time, West Indies fans make themselves known, a small section above the players' tunnel waving flags and dancing."
NZ 91-2
Ross Taylor, who hasn't quite got going in this World Cup, is the new man. The run rate is still good for New Zealand, around 5.5, but they will want to keep these two together for a while. He's away with a single to mid-on, but big Sulieman Benn is playing a real role here - just two runs from another tight over.
Post update
Ian Bishop
Former West Indies fast bowler on BBC Test Match Special
"The extra ball of the over has brought some success because of that no-ball. Maybe the ball held up a bit in the surface because it was a cut shot that didn't come out of the middle. Williamson has only hit one fifty in this World Cup so it's not been a great tournament for him."

Williamson c Gayle b Russell 33 (NZ 89-2)
Williamson was looking so good but he's back in the sheds now. Andre Russell foxes him with a brilliantly disguised slower ball, Williamson is through the attempted cut shot early and he misdirects it well in front of square, hitting it uppishly to short cover where Chris Gayle takes a good juggling catch. Big breakthrough for the West Indies.

"I always felt that was a little bit of guesswork. Yes it's Williamson, but you've got to be more certain than that."
NZ 86-1
Benn is crestfallen with that result, but he's not getting much turn and there was always a strong chance that that delivery wasn't turning back enough. He has come back very well after a poor first over though, keeping the Kiwi batsmen honest. Just four singles off that over.
Umpire review
Benn hits Williamson on the pads. The umpire says not out, but West Indies call for a review.
The ball is shown to be hitting the stumps, but not comprehensively enough, just shaving leg peg. It's 'umpire's call', and Williamson survives.
NZ 82-1 (partnership 55)
Now, can Andre Russell keep the pressure on? He begins with a short ball that Williamson pulls for a single to the boundary-rider at midwicket. Martin Guptill has just got a little bogged down here - two accurate deliveries from Russell extend his run of scoreless deliveries to eight before he steals a single with a drop-and-run defensive stroke.
Two more singles round out the over as New Zealand perhaps reset their sights to the goal of steady, risk-free accumulation. West Indies have come back well in he last few overs.

Andrew Samson

"McCullum & Guptill now have the most ODI partnerships together without one ending in a run out - 52. Viv Richards & Desmond Haynes had 51."
NZ 78-1
Benn has just regained a measure of control here, pushing the ball through faster and flatter and keeping Guptill tied down. A valuable maiden brings the New Zealand juggernaut temporarily to a juddering halt.
NZ 78-1 (Guptill 35, Williamson 28)
Another bowling change as Andre Russell, owner of the funkiest haircut as this World Cup, gets a bowl. New Zealand are getting a boundary off every over at the moment, they are so adept at keeping the run rate up at parts of the innings when other sides retreat into their shell. This time Williamson seizes on a toothless short ball and pulls it powerfully through midwicket.

"Just think next week, India v Australia. That will be the most popular India side ever to take the field. Pakistanis and Bangladeshis might be supporting Australia but everyone else will be rooting for India."

Benn continues, with a little more insurance now that the powerplay is over and he can have a few more fielders on the rope. No point having insurance when you bowl it there though, full toss outside off and Guptill gets it past the man on the boundary at deep cover. New Zealand motoring here.

NZ 63-1 (run rate 6.3)
Holder continues from the other end - will we see him bowl his set of ten straight through like he did in the previous match against UAE? Kane Williamson is a short man but he has a great ability to ride the bounce of the ball off the back foot, and he picks up four with a lovely cut shot past point.
NZ 57-1
An early introduction for the spin of Sulieman Benn. He starts badly, too short and Guptill pounces on it, rolling the wrists on it and flaying it past point for four. The batsmen exchange singles from the remaining deliveries to keep the run rate hovering healthily just above a run a ball.
NZ 49-1 (Guptill 22, Williamson 14)
Jason Holder has bowled a really nice length so far, just a little shorter than Taylor, making it much harder for the batsmen to drive him down the ground. He builds a little bit of pressure on Martin Guptill with four dot balls, but the batsman gets away off the fifth delivery, hitting a drive into the ground that bounces over the covers and brings three.

Graeme Swann

"West Indies are trying to bowl quite full, allowing the ball to move. There will be two people in this ground who will be very happy to see the ball moving in the air: Trent Boult and Tim Southee. They know they can wreak havoc if it's swinging."
NZ 46-1
The 'V' is proving a very productive scoring zone for New Zealand so far. Once again Jerome Taylor sees the ball whistle back past his toes as this time Kane Williamson meets a full delivery with the face of the bat.
Williamson has been a slow starter in this tournament but he looks fluent here and he follows that with another four, easing a drive past mid-on. And he finishes the over with a third boundary, poking at a ball outside off and flashing it through the vacant slip cordon.
NZ 34-1 (Guptill 19, Williamson 2)
Unbelievably, 31 is New Zealand's lowest five-over score in this World Cup so far.
The cultured Williamson is the handbrake to McCullum's accelerator - he will look to drop anchor and bat through here. Early jitters from the number three as he wanders out of his crease and scrambles back to sanctuary as the throw from Lendl Simmons whistles past the stumps. He gets off the mark with a single to third man.

Kane Williamson is the new man. Guptill, who certainly won't be forced back into his shell by the early loss of his partner, picks up another boundary with a punch through the covers.

McCullum c Holder b Taylor 12 (NZ 27-1)
Silly, silly, silly. McCullum's inability to take a backward step has cost him here. He tries to blast Jerome Taylor into the stands but doesn't time it at all, the ball slices up in the air towards deep cover, where Jason Holder extends his long tentacles to reel in an absolute blinder of a catch. One captain removes the other.

NZ 27-0 (Guptill 14, McCullum 12)
Brendon McCullum has been muffled so far - he's only seen one ball of the first three overs.
Now he gets his chance to eye up Jason Holder and immediately signals his intent. He advances down the track and a mistimed swipe is stopped at mid-on, but he doesn't miss out on the next two. First he whips a leg-side delivery off his pads for four, then he picks up a short ball and swats it into the stands!
Better yet, it's caught one-handed by a gentleman in the crowd, who wins a share of the million-dollar jackpot.
NZ 16-0
Martin Guptill is in no mood to hang around. Jerome Taylor is pitching the ball full to try and extract a bit of early swing, but he's putting it right into the Kiwi opener's wheelhouse at the moment. Two successive deliveries disappear straight back past the bowler, punched imperiously down the ground for four. The bowler drags back his length thereafter, but New Zealand are off to a good start here.

NZ 8-0 (Guptill 6, McCullum 1)
The ball is swinging early on for the Windies seamers. Captain Jason Holder takes the new nut at the other end. Sharp running is a feature of the New Zealand batting effort, and after ten balls, Guptill finally rotates the strike with a quick scampered single to allow Brendon McCullum to get in on the act.
McCullum repeats the trick off his first delivery, dropping the ball at his feet and setting off like a hare to beat the throw at the non-striker's end.

"By choosing to bat, I think McCullum is saying that in these types of games runs on the board matter more. Now they have to go on and post a decent total. They have been fallible in the past. Their batting hasn't been thoroughly reliable. There is always a bit of jitteriness. They have to play well from now on."
NZ 5-0
Well well, what a let off for New Zealand early on. Guptill connected sweetly but couldn't keep the stroke down and it should have been pouched. Prior to that, Guptill got off the mark first ball, slightly overpitched from Taylor and Guptill gave it the full face of the bat, caressing it down the ground for a handsome four.

Hold on to your hats...
This opening period could be very tasty. Here's why...
New Zealand have by far the best run rate of any team in the tournament in the opening ten overs, averaging well over 7 runs per over.
But West Indies bowlers have taken the most wickets within the first 10 overs of the innings in this WC: 15.
Post update
Stephan Shemilt
BBC Sport in Wellington
"This feels big. Throughout, it has felt as if this tournament has meant more in New Zealand and, in contrast to the half-empty Adelaide to watch Australia yesterday, the Cake Tin in Wellington is set to be sold out.
"Fans are streaming towards the ground along a vast concrete entrance, not unlike Wembley way. The New Zealand team bus even needed a police escort."
A tale of two captains
One of the most intriguing and potentially decisive subplots in this match involves the respective captains.
In the black corner, Brendon McCullum, a man widely regarded as the best skipper in world cricket. Audacious, talismanic and relentlessly aggressive, McCullum has been the driving force behind New Zealand's transformation from declining also-rans to rising stars of world cricket.
What a contrast between the ultra-experienced Kiwi skipper and the callow West Indies captain Jason Holder. Just 23 years old, the Barbadian has occasionally seemed a man out of his depth in this tournament as he tries to band together a seemingly dissolute side of big hitters and big egos.
However, the Windies captain has been very impressive with the ball - he could have a key role to play early doors today.
Routes to the last eight
Home comforts
New Zealand have won the last two World Cup matches between these sides in 2003 and 2007, and moreover, they have emerged victorious in all three ODIs played between these sides at this stadium.
The Westpac Stadium is a particularly happy hunting ground for pace bowler Tim Southee, who has taken 21 wickets at 12.00 in 6 ODIs at this venue.
Not only that, seven of the last eight completed ODIs between these sides have been won by the side batting first.
Gayle blows back into town
So, Chris Gayle is fit and raring to go. It is undoubtedly a boost to the Windies, but how does New Zealand captain Brendon McCullum feel about it? Not bad, actually...
"I don't think it changes things too much because we expected him to play anyway. He's obviously a world-class player and destructive on his day. The West Indies team are stacked with match-winners, not just Chris but many other guys in their line-up."
Team news
Both teams shuffle their pack. The headline news is that talismanic opener Chris Gayle is fit and plays for the West Indies - he replaces Dwayne Smith. Sulieman Benn comes in for Kemar Roach to provide a specialist spin option. For New Zealand, Adam Milne replaces Mitchell McClenaghan as the third seamer.
New Zealand XI: Martin Guptill, Brendon McCullum (capt), Kane Williamson, Ross Taylor, Grant Elliott, Corey Anderson, Luke Ronchi (wk), Daniel Vettori, Adam Milne, Tim Southee, Trent Boult.
West Indies XI: Chris Gayle, Johnson Charles, Lendl Simmons, Marlon Samuels, Denesh Ramdin (wk), Jonathan Carter, Darren Sammy, Andre Russell, Jason Holder (capt), Jerome Taylor, Sulieman Benn.
Toss
New Zealand win the toss and captain Brendon McCullum elects to bat first.
"The wicket looks good," he says. "It looks a bit different from the wicket we played England on. Runs on the board can be quite valuable in this sort of situation and hopefully we can get a few on the board."
West Indies captain Jason Holder says he's not too disappointed. "We're very confident coming into this game," he says. "There's a lot of pressure on New Zealand in their home town."
Hello
Welcome one and all to our coverage of the final quarter-final of the Cricket World Cup. It's New Zealand v West Indies in Wellington, for a place in the semi-finals against South Africa. Here comes the news from the toss...
No surprises?
So far, so predictable. After the hurly-burly of the group stage, which saw Ireland stun West Indies and Bangladesh upset England, the knockout stages of the Cricket World Cup have so far proved surprise-free.
Three quarter-final matches, three wins for the favourites, and if we're being honest, not a close game among them.
On paper, tonight's last quarter-final should be the most predictable of the lot. After all, West Indies were well below their best in the group stages, losing to Ireland and suffering an absolute hammering against South Africa. New Zealand, on the other hand, were superb, sweeping all before them to win six matches out of six.
With the Black Caps enjoying home advantage, they will be heavy favourites. But with the West Indies, you never quite know what to expect...
