Tammy Beaumont. Wow.
She waits for the slower ball, and ramps Hannah Rowe over fine leg, for a two-bounce four.
Lovely shot.

A smart bit of work behind the stumps. Amy Jones got off to an absolute flier, and when you're in those situations you just have to keep going. An important wicket but England are really well placed.
Jones st Martin b Satterthwaite 31 (Eng 127-3)
The change of angle works!
Amy Sattherthwaite eventually decides to go over the wicket, and Amy Jones, looking to come down the track, misses and is easily stumped by Katey Martin.
New Zealand really needed that.
Kate Cross
England seamer on BBC Two
We're not seeing any kind of thought process from the Kiwi bowlers. We're not even seeing field changes.
Amy Satterthwaite isn't getting this right. She allows Amy Jones to work through mid-wicket, again, before throwing it wide, which just allows Jones to reverse sweep.
That is the fifty partnership in just four overs.

They're the ones you really don't want to be dropping, especially when Tammy Beaumont has got herself going. It's a simple catch.
Oh no! A simple chance!
Amy Satterthwaite, surprisingly after going for 18 from first over, gets a second over, and Tammy Beaumont flicks the ball straight to Kiwi skipper Sophie Devine at mid-wicket, who spills it.
Big, big miss.

Tammy Beaumont is one of - if not the - first name on the team sheet.
Beaumont 64, Jones 24
FOUR FOURS IN FOUR BALLS!
Tammy Beaumont advances down the track and lofts over the covers for another boundary.
England have had a really good little phase here. They are on track for a big score.
Kate Cross
England seamer on BBC Two
A really good phase for England. They've capitalised on the bad balls. It's bread and butter for Tammy Beaumont.

This has been a really good 10 balls for England. They're really looking to put their foot down.
Short, wide and thumped to the boundary by Tammy Beaumont. You really can't bowl there to her. I've warned you once.
Four more! Three in a row now! Tammy Beaumont gets down and sweeps Leigh Kasperek fine for another boundary.
Tymal Mills
England pace bowler on BBC Two
Beaumont is one of the top batters in the world game at the moment. She's playing low risk cricket, timing the ball really well.
There's no bad way to bring up a half-century, but a lofted drive for four, over the covers, is up there as the ways you'd love to do it.
Superb shot, and Tammy Beaumont brings up her 10th T20 international century.

This has been an excellent over. Amy Jones is batting brilliantly and England are looking to post a really daunting total.

That side of the ground, Jones will pepper it all day long.
And again! Amy Jones picks up her third boundary in the over by going deep in the crease and pulling between the deep mid-wicket and square-leg fielders.
FOUR MORE! Wow. Four in the over from Amy Jones. She again pulls Amy Satterthwaite to almost the exact same spot.
Poor from New Zealand and Satterthwaite. She was bowling round the wicket, and the angle was just playing to Jones' strength.
Tymal Mills
England pace bowler on BBC Two
She's putting the bowler under real pressure. She's hitting where the bowler wants to be hit, there are three fielders there. But Amy Jones is finding the gap.
Four more! Amy Jones loves a boundary.
She whips Amy Satterthwaite through mid-wicket and it pierces the deep fielder at long-on and mid-wicket perfectly.
