I do feel that New Zealand are travelling at between four and five at the moment in this middle section. That is just down on where they would like to be. They would like to be pushing sixes if they can.

Right now, they are scoring two-and-a-half-shots an over. They need to lift that to three-and-a-half to score the six they need.

It is about pushing it around, moving players around to put pressure back on the opposition.

Shakib completes his 10-over stint, the highlight of his final set of six coming when Neil Broom bunts a boundary through the off side.

Generally when you run out your skipper - or at least are involved in your skipper's run out! - you need to go big. Over to you, Ross Taylor.

Neil Broom made his only one-day century - an unbeaten 109 - against Bangladesh at Nelson in December 2016. He averages 61.85 against the Tigers.

Mashrafe begins his run-up to the crease from a starting point littered with red lines and marks on the lush green turf. It looks like a group of schoolchildren have been let loose with the chalk on the street. It's another good over from the muscular paceman who almost gets rid of Broom only to see a catch off a leading edge fall just short of the fielder.

Brendon McCullum is on the ball when it comes to New Zealand one-day cricket stats...

Test Match Special producer Tim Peach has lined up a decent interval programme for you today - first there's Jonathan Agnew's interview with Eoin Morgan, then Surrey chairman Richard Thompson will be on to talk about The Oval's recently-announced redevelopment.

Peach, by the way, is captain of the BBC Radio team which is up against the BBC Sport online team in a game in a few weeks. Online are 7/4 favorites for victory with the bookies, I believe.

Shakib, bowling darts rather than sharp spinning deliveries, is worked into gaps by the batsmen. Seven from the over - all of them in ones and twos.

Neil Broom is the new batsman. Please, no jokes about sweeping.

Bangladesh celebrated that wicket like they'd won the match. A fella in a tiger onesie was dancing with delight in the crowd. He looks like the Tiger That Came To Tea.

New Zealand's cupboard has looked bare in recent games once Kane Williamson has departed. Broom begins nicely, mind, as he drives four back down the ground.

There isn't a single there. Williamson committed himself so hard as he knew it would be tight. He had travelled a long way and left himself too much to do.

Taylor wasn't looking for the run. It is just an awful mix-up. He does this time and time again. This is the important phase of an innings. This is the part where New Zealand have failed in this tournament. They have imploded.

You know when you're playing street cricket and you get a filthy delivery which you set yourself for before hammering it into the next cul-de-sac? That's exactly what happens here when Shakib's radar goes awry and Ross Taylor shovels four down to backward square.

A sign of Bangladesh's growth as a cricketing nation is the battery of decent seamers they have assembled. They're always going to have decent spin options but the fact they can field three or four players who can trouble top batsmen in these conditions is good to see. Mortaza is an experienced campaigner and he deceives Williamson with a slower ball which ends an over costing just one run. Perhaps New Zealand will be awoken from their mid-innings slumber if we all shout 'Sri Lanka' as one?

I don't think I've ever seen Kane Williamson out of form. He's certainly on it today - just take a look at this for timing.

This is an important game and you can tell it is important because there is a cageyness about both teams. It is quite old school. No risks. The Kiwis will be happy they are accumulating in a way that has somewhat gone out of fashion.

Today's umpires - Ian Gould and Nigel Llong - are wearing bright yellow jackets in the Cardiff gloom. They look warm and dry but far from fashionable. Almost like a workplace freebie which you wouldn't use outside of the workplace. OK, maybe it'll do for walking the dog?

Rubel is knocked around for ones and twos. New Zealand look like they are keen to push on, but wary of their lower order travails in their two previous games in this tournament.

Shakib, collar upturned like a cricketing Cantona, continues and Ross Taylor uses his feet to punch a single down the ground. Kane Williamson prefers to stay on the back foot. Either way, four singles are effortlessly added to a growing total.

Thanks Amy. What have I missed? Quiet news day?

That's it from me for a bit, I'll leave you with Marc Higginson.

And that's four for Taylor - a bouncer from Rubel and Taylor, almost lazily, swats it past square leg and away to the boundary. There's tehn a real mix-up as Taylor and Rubel collide mid-pitch, Williamson has to spin round and dive back to reach the crease, and manages it just before Mustafiqur whips the bails off. What a mess that would have been.
