Wyatt 38 (33 balls), Sciver 14 (9)
Sciver sweeps, a touch of the soccer skills from Chedean Nation as she runs round at deep square leg and sticks a boot out to cut off the boundary.
The Surrey Stars skipper is rapidly into double figures as she guides one to long-on - Wyatt is quick between the wickets, Natasha McLean isn't quick in the field, and they run two.
And Sciver finishes the over with an even better sweep for four. Looking ominously good.
Wyatt steps across to whack a very wide delivery from Fletcher for four through cover point. A single takes her to 38 from 33.
And here's the first six of the day for England, from Amy Jones:
Here's one of the several "lives" Danni Wyatt has had today...
A classy four from Nat Sciver as she carves Chinelle Henry through mid-wicket for four. Another fierce drive is... stopped at mid-off, but the fielder falls over while cutting it off, and they can complete the single.
Wyatt drills a single to long-off to move to 33 from 30 balls.
Here's the first of our highlights - Danni Wyatt whacking a four over extra cover.
Wyatt 32 (29 balls), Sciver 1 (1)
Natalie Sciver in at four. She blocks her first ball but immediately sets off for a single, the throw from the cover hits Sciver as she makes her ground and there are some half-hearted thoughts about appealing for obstructing the field... but she had run in a straight line so there's nothing doing.
Despite those wickets, England looking relatively strong at the halfway point. But can those wickets inspire West Indies?

Beaumont was trying to drill it back down the ground. Those catches either stick, or you get nowhere near them, and that stuck.
Beaumont c & b Fletcher 2 (Eng 72-2)
Beaumont's off the mark - but just as quickly back in the hutch as the comes down the track to Fletcher but spins the left-spinner a return catch, which she takes.
We're nearly halfway through the innings, and time for West Indies to reveal their fifth bowler. It's leg-spinner Afy Fletcher, who is expertly ramped over her left shoulder by Wyatt. This pair are quick between the wickets, and quickly back for three.
Meanwhile, the other England players look very relaxed on the balcony. Katherine Brunt is messing around with Sarah Taylor, flicking her nose when the camera's on them, while Anya Shrubsole is being assisted with what looks like a crossword book by, appropriately, Kate Cross.

England are setting up a line-up that could genuinely win the World T20 next February. They've closed up a couple of gaps in the batting order, and Sciver and Knight are a serious engine room in the middle.
Tammy Beaumont, England's regular ODI opener, is having to be content with batting at three in T20 these days. She times her first ball brilliantly - but cuts it straight to a fielder.

It's the right idea as the field was up on the leg side. She had the stumping reprieve early on, then really capitalised. And this batting line-up is very deep.
Jones b Henry 37 (Eng 67-1)
A good start by Amy Jones is ended as she steps across to the off side, trying to hit to leg, but drags the ball onto her stumps. Her 37 came off 27 balls.

You have your bad days in the field, but West Indies look like they've gone back to how it was in the first ODI. It shouldn't happen if you're doing an hour or two of fielding practice each day.
Danni Wyatt - the great survivor - now survives an lbw appeal. But some careful ones and twos take 12 off Taylor's over.
Wyatt takes a fresh guard against Taylor, nudging a single.
At the other end, Amy Jones is on fluent form, expertly sweeping for four.

We have our first six of the day! Amy Jones lofts the last ball of Henry's over, over the ropes at long-on. That's the 50 up for England.
Jones has 29 from 22 balls, Wyatt has 23 from 20.
Having shelled that chance at mid-off, Chinelle Henry gets the chance to redeem herself with the ball. Her right-arm medium pace serves up three dot balls before Wyatt, who's still riding her luck, gets an edge past the keeper for four - then miscues one in the air over the bowler's head, but it falls safely in front of long-on.
Danni Wyatt will soon officially be a cat with the number of lives she's had today...
