"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."

Andrew Samson
BBC Test Match Special statistician

"The highest World Cup knockout total is Australia's 359-2 v India at Johannesburg in the 2003 final."

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.

"That has to go down as the worst review of the World Cup. But when you're having such a good time out there, you don't want it to end."

Plumb as plumb can be. Hawk-Eye says the ball would have hit the middle of middle stump so Elliott is obliged to walk.

Scorecard

One ball after spanking another six, Elliott sweeps, misses and is given out by umpire Oxenford. This looks plumb. But he's going to review. it...

Ex-New Zealand captain on BBC Test Match Special

"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)."

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!!

"Brilliant atmosphere in Wellington now as the crowd chant for their batting here. 'Gup-till, clap, clap, clap, Gup-till'. If he continues, we could have the second World Cup 200, with both double centurions playing in this match."

Graeme Swann
Ex-England spinner on BBC Test Match Special

"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."

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.

The highest scores for New Zealand in ODIs:

• All ODIs: 189 not out - Martin Guptill v England in Southampton in 2013

• World Cup: 171 not out - Glenn Turner v East Africa in Birmingham in 1975

Grant Elliott is the new man and is straight into the runs with a couple to third man and some sharp running. I suggest you leave the bulk of the work to your partner Grant. He's got lots of records in his sights.

Corey Anderson's brief cameo is over. He tries to slog Andre Russell over midwicket but gets it off the toe of the bat and the ball spoons to Chris Gayle, who takes a good catch on the stretch.

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.

Gav Cartmel: West Indies would definitely match the French Football team. So much talent, no temperament but when they're on, they're on.

Corey Anderson is in his element. A short ball from Andre Russell is catapulted for six over deep square leg, then he check drives over the infield for four. Who can stem the flow of runs here? Captain Holder's going to have another dash...

You've started something there, College Hill Tutor. Who would West Indies be?

"Martin Guptill has made the first 150 in a World Cup knockout game. The previous highest was 149 by Australia's Adam Gilchrist against Sri Lanka at Bridgetown in the 2007 final."
