Tammy Beaumont has played some beautiful drives, perhaps against some generous half volleys, but her footwork has been perfect.

Five runs off Afy Fletcher's over coming out of the drinks break.

We've had 15 deliveries without a boundary - a drought!

This is a somewhat depleted West Indian team. I'd like to see them start to take a few more risks.

This is the first time in three years that England have had back-to-back century opening partnerships.

Another reasonable over from Jannillea Glasgow going into the drinks break, with Jones and Beaumont each taking a two and a single.

Hundred up for England, as Jones eases Fletcher's opening delivery into the covers for a single.

She adds another four, her 11th, beating the fielder at deep third.

Better for the West Indies, with only one run coming from Jannillea Glasgow's over as Amy Jones turns her opening delivery into the leg side.

They'll need a few more of these to make this match competitive.

There's good technical cricket being played, Amy Jones just pressing forward then rocking back. It was a regulation boundary.

The veteran leggie Afy Fletcher comes into the attack in place of Claxton and Amy Jones heaves her fifth delivery through mid-wicket for another four.

I'd like the West Indies to play to their strengths a little bit more. They need to pick out everyone's strength, what is each persons strongest ball.

Once they've picked it out, then they should set the field. At the moment they are setting the field then trying to bowl to match it.

You can't hear too much noise from the field out there. Their shoulders have dropped.

On the legs from Glasgow and Beaumont turns the ball away for four through backward square.

She's on 36 from 31 at the end of the over.

50 for Amy Jonespublished at 11.1 overs

11.1 overs

And there's the half-century for Amy Jones!

She continues to enjoy her promotion to opener, after scoring 122 at Derby she reaches 50 from 41 deliveries today, taking to a single to mid-on off Glasgow.

I don't think I'd seen a slow ball bowled today until that free hit.

You've got to play to your strengths, there's been some great slow ball deliveries since. Do the West Indies need to look at taking some pace off?

This is England’s highest unbeaten powerplay score in ODI cricket, surpassing the 68-0 they made against New Zealand in Durham last year.

Bowled her but it doesn't count! Beautuiful delivery.

Not so great from Claxton, her first ball is a chest-high no ball that Beaumont dispatches for four through backward square.

That results in a free hit, and the 21-year-old sends down a tidy slow ball that bowls the England opener, who was taking a massive waft.

A couple of singles close the over, with Jones moving to 49 and retaining the strike.

Jannillea Glasgow, a 21-year-old seamer, comes into the attack for the final over of the powerplay, replacing Cherry-Ann Fraser.

England take a trio of singles before Jones cracks the final delivery of the over through long-on.

England finish seven short of their highest powerplay score, but 32 ahead of their score at Derby, when they went on to make 345.

It's been a really good over so far from Jahzara Claxton, shame it couldn't be taken.
