In the last Windies game against the UAE, Sammy was pulled out of the attack after one over. This is a great response. Another tight set leaves him with figures of 6-0-21-0, which is outstanding in the context of this match.

Guptill goes skywards, but it hasn't got the legs. Jerome Taylor comes in from the long-on boundary, but can't make it in time to take the catch. Guptill is a relieved man. His head sunk after he hit the shot. He thought he was a goner.

Scorecard

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.

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."

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."

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.

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.

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.

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?

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."

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."

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.
