7.31pm Right, that'll do for tonight. Remarkable scenes in Bridgetown, as England launch their World Cup year with intent. Goodnight!
Roy has reappeared: "A big total, quite daunting at the start. I still have a deficit of 20 [after dropping Gayle] so have some making up to do. We rotated the strike extremely well, and as a team we keep striving for better and better. Will keep our feet on the floor and keep working for Friday."
Jason Roy is the Man of the Match: Morgan picks up the award on his behalf, and here's Morgan for a chat: "The calm nature with which we came back with the ball [was pleasing]. We went about the chase well, with a short side and a howling wind. Felt like a 330-chase, not a 360. For Jason to play such a commanding role set us up beautifully. When he and Root bat together they complement each other. They had a fantastic day today, we're off to a winning start and we're delighted."
"We didn't have a great day in the field and we'll like to improve that going forward. I'd like to think we are improving constantly as we go along, which is a good place to be going into the World Cup."
7.22pm Time for some presentations. Here's Jason Holder: "At the halfway stage we felt we were in the game, but didn't bowl as well as we'd have liked and didn't help ourselves in the field."
"Credit to Chris, he's been a stalwart for us. But we need to pull our socks up. Our energy and body language wasn't up to scratch, and the bowlers need to create more opportunities.
7.20pm Annan Boodram: "Had those catches been taken England would have lost this game." Does that include Roy's off Gayle? Oddly, it might not ...
7.16pm Deepak Samson: "6s and 4s may win you fame...but 1s and 2s win the game !!!" I like what you did there...
Ghaffar.DawnNew: "4:05am in Pakistan..following this Classic on Cricinfo. Lovely life Cricket Life. Also not bad West Indies. They are on track" That's some hard-core commitment to run-chasing!
7.08pm England have cruised to their highest ODI run-chase, with eight deliveries to spare, and in their first ODI of a World Cup year, well, that is quite some statement of intent from the World No.1s and tournament favourites.
Jason Roy set the platform with a blistering 65-ball century, before Root and Eoin Morgan dived into the meat of the chase. It takes quite something to steal the thunder from a Chris Gayle masterpiece, but ultimately, the accumulation of a world-record 23 sixes couldn't atone for West Indies' lack of intent between the wickets. England find the boundaries and sprint the singles at will, and that made all the difference.
John: "Buttler the hero with a faultless innings at a 400 SR. Breathtaking stuff." Well quite, scene-stealing stuff
Sarun: "Root does he same role in ODI for England similar to what Pujara does for India in tests. Let all the swashbucklers play around him. His position is never in doubt and never should be. "
Out comes Buttler with a fairly routine requirement
Root shakes his head as he departs, but that was a clinical performance from one of England's outstanding cricketers. He's broken the back of an extraordinarily steep chase
JE Root c Pooran b Holder 102 (167m 97b 9x4 0x6) SR: 105.15
Tony: "Is wondering the irony if Stokes scores the winning runs and leaving Root stranded on 98 after that declaration the other week" ... 48 not out and 98 not out are different beasts, but yes, cruelty is in the offing...
