Holder takes 4-7 in 3.4 overs

First of five T20s; Barbados
Time for us to call it a night.
Have a read of Stephan Shemilt's report as England's batting woes cross formats and continents.
We'll be back on Sunday evening for the second T20 between West Indies and England - that is again a 20:00 GMT start.
Want more cricket before then? We've got you sorted. It is the third T20 in the Women's Ashes between Australia and England from 03:00 GMT.
Enjoy your Saturday night!
West Indies captain Kieron Pollard: "That is the sort of blueprint that we asked to guys to come and show. I am very happy for them. Winning games is rarity for us and to see the guys finish it off and finish not out is fantastic.
"Sheldon [Cottrell] showed his quality and Jason [Holder] always steps it up on his ground - he was phenomenal. The guys then really backed it up in the field and they really put on a show today.
"We have really worked hard, and yes it is the first of five, but winning games is not easy as all."
England captain Eoin Morgan: "It was the opposite conditions to what we played on two or three days ago in the warm-up game. They dominated the game. We didn't seem to adapt well enough in running and that is what you have to do when you are challenged with a bit of movement and bounce. We'll have to come back with a fresh game plan tomorrow and tackle it head on because conditions could be very similar.
"We spoke pre-game about there being more bounce. We found it tricky today that it wasn't consistent but we found the balance between risk and reward difficult today. Hopefully we'll do that better tomorrow.
"You get tested and exposed in international cricket. I'll be encouraging them to stay positive."

The last series against Ireland was a tough series and I wasn't happy with my performance but it is good to bounce back in this manner and we always speak in the changing room about tackling adversity face on.
"We had the perfect day to be honest. There isn't much I can pinpoint that we did wrong. The challenge for us is backing it up."

Tomorrow's game has to be better, surely?

Daniel Seal: Has to be up there as one of the most boring T20 run-chases of all time!
West Indies won with 17 balls to spare in the end.
Brandon King finishes unbeaten on 55 and Nicholas Pooran made 27.
They put on 52 for the second wicket.
What's the one thing you want after a heavy defeat?
The chance to redeem yourself, right?
Well, England will have just that. The second game in the series is at 20:00 GMT on Sunday.
There we are.
An absolutely thrashing for England and a comfortable victory for West Indies.
They take a 1-0 lead in the five-match series.
The scores are level...
Brandon King and Nichola Pooran have put on 51 for the second wicket now.
WI 101-1, need three to win
Well batted, Brandon King.
He reaches his second T20 international half-century from 47 balls with four fours and one six.
Need four from 21 balls
Four more.
Slower ball from Saqib Mahmood and Brandon King just waits for it before slapping it to the cover boundary.
One hit is all it needs...
Need nine from 23 balls
Shot!
Saqib Mahmood is back on, and absolutely stacks it in his follow through, and Nicholas Pooran cuts for first ball for four.
Single figures required...
Need 13 from 24 balls
West Indies are just playing risk-free cricket to get over the line.
They take six runs from Tymal Mills' third over. He's 0-19 from three so far.
England's pace bowlers haven't had anywhere near the impact that West Indies' did on this pitch. Kieron Pollard did say he thought batting would be easier under lights and it has definitely played out like that.
Need 19 from 30 balls
Image source, Getty ImagesAdil Rashid is done for the day. West Indies take four from this final over and he finishes with 1-21.
I've missed the start of Match of the Day quite comfortably in the end. West Indies have gone about this in a sensible, if not rather dull, manner.

Need 23 from 36 balls
Decent comeback from Tymal Mills, conceding just two singles off the remaining five balls of the over.
Mills will want to impress in this series. He did well when he came into the side for the World Cup but he is by no means a guaranteed pick at this stage.

Need 25 from 41 balls
Tymal Mills comes back on for England and he offers Brandon King a little bit of width.
The West Indies opener climbs into it and cuts away for four. A half-century is in the offing for King.
Need 29 from 42 balls
Eight runs from Chris Jordan's and West Indies are cruising towards a 1-0 lead in this five-match series.
Could they get a bit of a move on, though? I've just realised I've still got to make my bed when this is over...
