Seam bowlers have found more powerplay swing in Dubai (2.0°) compared to Sharjah (1.6°) across the tournament. Swing may be key for the Windies bowlers to make early inroads into this England batting line-up.

Chinelle Henry continues to find some movement through the air.

Maia Bouchier charges down the track to negate that swing and skews over the off-side field for two, before an inside edge brings a single to square-leg.

She's not quite got going yet, the England opener.

Danni Wyatt-Hodge rocks back and punches through the covers for a couple to finish the second over.

It was slashed at Ashmini Munisar and dropped at cover. She had to come forward, but it was a regulation chance and it has bounced out of her hands.

Bouchier dropped on threepublished at 1.2 overs

1.2 overs

Eng 5-0

Spin to open up from the other end, as Zaida James - back in the West Indies side - shares new-ball duties.

And she should really have a wicket with her second delivery as Maia Bouchier skews one straight Ashmini Minsar at cover.

Straight in, and straight out. A life for Bouchier.

My gut feeling is that England will need a total above 140.

That will prove to be a tricky chase for West Indies who will have to go all the way through. But England will first need a good powerplay, and Maia Bouchier and Danni Wyatt-Hodge will once again have a big role to play.

With England playing their first game of the competition in Dubai batters will have to take a few moments to get used to the extra bounce.

Balls from seamers pitching around 6m in length have, on average, been bouncing 8cm higher here than in Sharjah across the competition to date.

Maia Bouchier and Danni Wyatt-Hodge trade singles, before Bouchier takes two through midwicket in a pretty low-key first over.

Danni Wyatt-Hodge is 37 runs away from becoming the first player to score 3,000 runs for England in women’s T20 internationals.

The first ball of the game is punched to cover by Maia Bouchier for no run.

There's a gentle bit of away swing on offer for Chinelle Henry.

The anthems are done, Chinelle Henry has the new ball for West Indies and Maia Bouchier is on strike.

Here we go...

Since the start of 2020, the West Indies have won 14 of their 27 (52%) completed games where they have chased.

England have batted first 43 times in that same time frame, winning 31 times (70%).

England have been building to something special in the last couple of weeks. I think they have carried the momentum nicely during the last couple of weeks and they've got themselves into a really strong position.

But I don't think this is going to be a walkover or an easy outing for England. West Indies are unpredictable and they are also World Cup winners. They won't be shying away from playing some shots today.

England have won their last 13 women’s T20 internationals against West Indies – their longest winning run against a single opposition in the history of the format.

Watch the best shots from England's last outing, as openers Maia Bouchier and Danni Wyatt-Hodge scored 62 and 51 respectively in the win against Scotland.

England will qualify for the semi-finals as group winners if they beat West Indies this afternoon.

If England lose, then they, West Indiesand South Africawill all finish on six points and net run-rate will determine which two sides advance.

Despite holding a healthy net run-rate after three games, England are under pressure because, barring extreme scenarios, Heather Knight's side's total will drop below both West Indies' and South Africa's with any defeat other than one by the slenderest of margins.

If West Indies bat first and score 130 in 20 overs and England manage 129 in 20 overs reply - i.e. a one-run defeat - England would go through, but if they were lose by two runs in that scenario they would go out.

South Africa will go through if England beat West Indies or if England suffer a defeat that drops their net run-rate below +1.382.

West Indies need to beat England to qualify and any margin of victory will almost certainly be enough given their net run-rate advantage over South Africa.

Got it? Good.
