Mostary whips Charlie Dean for a couple of twos, but the England spinner strikes pad with her third ball.

Up goes the umpire's finger, Bangladesh review.

Linsey Smith has been hitting the stumps 56% of the time today, very impressive. I'd love to see the rest of the bowlers today, it's probably half of that.

Allow us, Katherine: Charlie Dean 55%, Sophie Ecclestone 32%, Sarah Glenn 25%.

Fahima Khatun arrives with a near impossible job on her hands.

She takes a first-ball single out to square leg - more needed.

Finally, a ball on the stumps. It kept slightly low, a bit of an off-cut action. It was effective.

Dean, Ecclestone and Glenn are the three best spinners in the world. In terms of stats, they've been much more expensive than Smith, who has also taken key wickets and fielded well. She's giving Jon Lewis a proper selection headache. Things to think about.

Ritu Moni enters for Bangladesh, she gets off the mark with sweep towards square.

Smith closes with figures of 2-11, the required run-rate is exactly 12.

Somebody needs to come in and break this partnership, Linsey Smith seems to be that person today. It changes game by game, but today it has been Linsey Smith and that's where they've gone next.

Bangladesh hustle three more runs from the over.

More signs of intent, with Nehar coming down the track but only managing a single down the ground.

The timing and pick-up of that shot from Mostary was lovely. It was quicker but short from Charlie Dean and Mostary was on it like a flash.

Ban 76-4published at 15.3 overs

15.3 overs

Walloped!

Charlie Dean drops the ball rather short and Mostary dispatches it over square leg on the swivel for the first six of the innings.

Mostary is actually going very well. The clarity of the situation is making her really positive and she knows what she needs to do.

Mostary might have expected four there - she gets plenty of bat clouting Sarah Glenn out to mid-wicket, but Maia Bouchier has time to run round and save a couple of runs.

Taj Nehar takes two for herself, lifting out to Danni Wyatt-Hodge at deep cover.

That's Glenn's evening done, she finishes with figures of 1-22.

Hmm, a touch of a chance.

Taj Nehar tries to turn Sciver-Brunt into the leg side, but skews the ball over mid-on where Danielle Gibson flails at the ball as it passes over her head.

From the following delivery, Alice Capsey does good work diving to her right to restrict the Bangladesh batter to a single.

Taj Nehar is in at six for Bangladesh, she gets bat on the last four balls of Glenn's over but doesn't score.

Meanwhile the required run-rate has crept over nine.

Not the biggest turner of the ball, this time Sarah Glenn finds a little bit of turn. She's so skiddy and quick through the air, one Shorna Akter probably needed to come to.

Shorna Akter arrives at the crease and picks up two from the final ball of the over, edging past short third.
