Jones and Beaumont take a single apiece - it's looking very comfortable out there.

It's been pretty much chanceless from Amy Jones. She's taken on the ball and played some beautiful strokes.

A second consecutive ODI hundred for Amy Jones. It's been an outstanding innings from just 76 balls.

Amy Jones' century in 76 balls is the joint-third quickest in England women's ODI cricket.

Back-to-back hundreds for Amy Jones!

After going 12 years without an ODI hundred she does it in consecutive matches, firing her 16th four of the innings through the covers off Karishma Ramharack.

It comes off 76 deliveries.

50 for Tammy Beaumontpublished at 23 overs

There's Tammy's half-century.

She sends Afy Fletcher's third delivery square for two, reaching the 50 from 64 deliveries and taking England past 150 in the process.

Four more runs from the rest of the over, next up an Amy Jones century?

The pressure today is on because everyone should be scoring a hundred here against the West Indies, especially on this surface.

England are making the most of the beautiful batting conditions out there.

Karishma Ramharack comes into the attack after Jannillea Glasgow's expensive over and Jones dispatches her first ball through long-off for a one-bounce four.

Tammy Beaumont, on 49, can't get the last two deliveries of the over away, so will have to wait for her half century.

This might be the race now, can Amy Jones get her century before Tammy Beaumont gets her half century?

Fletcher tightens it up, with England taking three singles off her fifth over.

The West Indies are having a bit of a shocker at the moment.

Everything just looks so easy for these two at the moment. There's no dots and there's no pressure.

After 27 deliveries without a boundary, they all come at once.

A trio of Amy Jones fours start the previously fairly economical Jannillea Glasgow's sixth over - the first through mid-wicket, the second guided past the keeper, the third through backward square off a no ball on height.

Jones takes a single from the free hit and the openers take four more runs off the remaining deliveries for 18 off the over.

A couple more singles to finish the over.

The opening partnership reaches 122, after making 222 in Derby on Friday.

I didn't think it turned like that.

They've made umpire Sue Redfern look a bit silly.

Oh!

Well, that looked out, but ball-tracking says otherwise.

The ball turned a lot to get under the bat and it turns out it would have spun enough to miss the off stump.

Beaumont will stick around on 44.

Jonathan Agnew
BBC Chief Cricket Commentator on Test Match Special

I think it's unlikely to be going over the top. I've a feeling it's going to be out.

Hello, hello.

Up goes the umpire's finger as Tammy Beaumont is struck low on the front pad attempting a sweep off Afy Fletcher.

The England opener is going to review it...

Make that 21 deliveries without a boundary!

A single apiece for Jones and Beaumont as Glasgow continues.
