Sophie Ecclestone has bowled beautifully. It is what we come to expect from the number one-ranked T20 bowler in the world. You forget she is just 23 but she is such a big character. She really is the heartbeat of this bowling line-up.
James lbw b Ecclestone 2 (WI 130-7)
Two in three balls for Sophie Ecclestone.
Zaida James swings at her first ball and gets two. She swings at her second ball, misses and is plumb lbw.
Fletcher lbw b Ecclestone 10 (WI 128-6)
Clattering into leg stump! The review pays off for England. They have their sixth.

Sophie Ecclestone's reaction is one of somebody who is certain this is out.
Review that!
Afy Fletcher swings, misses and is hit on the pad. The umpire says no but I'd be wanting another look. England do too.
West Indies are swinging in this penultimate over but are yet to really make proper contact.

Whatever happens in the next two overs England will have to play well.
West Indies looked like getting more at one stage but 140 would still be a decent effort.
Can they get there?
That's a good shot from new batter Afy Fletcher, who plays a reverse-scoop shot to the boundary off Charlie Dean.
An edgy three follows.
Important runs.

I think 130 on this pitch is very chaseable.
Though the way they have been talking in the media I don't think England will be afraid to take on any total.
Sophie Ecclestone removing Hayley Matthews started this slide...
West Indies were 58-1 after eight overs in this game.
England, despite leaking a few too many wides, have come back very well.

She had time, took aim and decided to take out some timber at the non-striker's end.
Henry run out Knight 14 (WI 113-5)
Brilliant!
Chinelle Henry takes on a suicidal run after hitting the ball straight to England skipper Heather Knight at extra cover. Knight takes the ball, steadies herself and throws down the stumps with a direct hit.
The diving Henry is well short.

Campbelle c Jones b K Sciver-Brunt 34 (WI 112-4)
Shemaine Campbelle is out this time! Just after chopping Katherine Sciver-Brunt for four she tries a similar stroke but this time gets a thin edge.
Keeper Amy Jones is standing up to the stumps and that ball has bounced. It's a really good catch.
There's the tiniest squiggle on Ultra-edge. Shemaine Campbelle survives.
Has Sophie Ecclestone got another? England send an lbw shout against Shemaine Campbelle upstairs.
Shemaine Campbelle is playing a good hand in fairness. A full toss follows a wide from Ecclestone, I haven't said that very often before, and the right-hander drives for four down the ground.
