9.24pm: That will be that from us tonight. Valkerie's report will appear here very shortly, and we'll be back on Wednesday evening for the 2nd T20I. Thanks for your company!

Tammy Beaumont is player of the match: "It's been a very long time. It was good to be back at the top of the order after a very, very long lay-off. I feel like I've been playing for my place since January time, so it's made me look at my game and be more aggressive at the top. At the minute it's going quite well and it was good to put that into action in a real game rather than one against each other. It seemed to skid on quite nicely - hopefully it'll be good for the next four games."

Heather Knight: "Really pleased, delighted to be back and thought it was a really good performance. We ideally would have got a few more, but we were outstanding with the ball. Tammy was great - got us off to an amazing start. She'd done it in the warm-up games, so really pleased she did well. We're looking to win the series, but to keep improving all the time."

Stafanie Taylor: "It's not one of our best [performances]. We didn't adapt well to the pitch. Tammy batted really well and set the game up nicely for them. Looking back at that, we thought we were always behind and had to gain some momentum going into the batting. Some bowlers bowled well in patches but... not the best, really. Deandra batted well, but she needed someone to stay there with her. We thought too many dot balls strangled us a bit. We needed to go back to the footage and assess it, and see areas we can improve on. We have a training day tomorrow just to fine tune for Wednesday's game. I'm not sure if there will be many changes."

9.12pm: Well, a routine win for England in the end. They got off to such a good start with the bat, thanks primarily to Tammy Beaumont, that their late-innings slump mattered little. West Indies never really looked in the game, despite some lusty blows from Deandra Dottin - in particular, that towering 88m six over the leg side. But with nobody else reaching double figures, their run chase never got started, and Dottin put her foot down too late in the piece to get them close. Anya Shrubsole was expensive, but other than that England were excellent with the ball, and their extensive pre-series preparation has clearly paid off. Stick around for the presentation, coming up shortly.

48 off 1 ball. Just keep your foot behind the line!

And now dead ball is called halfway through Brunt's run-up! One fielder too many outside the ring, this time

Bit of a delay here... some problem for Brunt, by the looks of it? They're looking for some sawdust, apparently! Four balls to go, 50 runs needed, and Brunt is insisting that she needs some sawdust! Can you believe it? A member of the Derby groundstaff has come out with a bucket, at snail's pace... he's finally broken into a jog! And is now walking again. I'm not sure this actually is sawdust, it's bright blue for a start! And now the Benny Hill music as he sprints off... surreal stuff

Brunt to finish the job for England.

51 needed off the last. Coach Keightley has a hot water bottle down in the dugout... reckon it's a chilly one in Derbados!
