England drew first blood in the one-day series against West Indies, winning a rain-hit match by 114 runs via the D/L method.
Ian Bell marked his return to the one-day side with an assured century as England made 288-6, Jonathan Trott (42) and Craig Kieswetter (38 not out) adding useful runs.
West Indies began their reply brightly, reaching 95-1 with Dwayne Smith making 56, before eventually collapsing to 172 all out either side of a rain delay.
Seamer Tim Bresnan took 4-34 as England won with more than 14 overs left on a cold and windy day at the Ageaus Bowl.
Bell was passed fit, for his first assignment as the retired Kevin Pietersen's successor at the top of the order, having edged a pull into his face in indoor practice - a mishap which resulted in 10 stitches and an x-ray on his jawbone.
He produced a chanceless innings of trademark timing and placement - with 12 fours and one six from 117 balls - after England were put in under cloudy skies.
They were almost instantly without their captain and Bell's opening partner Alastair Cook, but a second-wicket stand of 108 in 20 overs put them in good shape.
Cook departed to the third ball of the match, from Ravi Rampaul, pushing forward and edging a modicum of movement behind.
Yet it was a near score draw in the first over after West Indies squandered their only review on an lbw appeal against Jonathan Trott.
England's number three first found the boundary, clipping Andre Russell handsomely off his toes from the final ball of the fourth over. Then in Russell's next, Bell was ready to put his stamp on proceedings.
A memorable six, struck high over long-off from a length ball, was followed by three fours in five balls - a cut, a pull and another drive on the up wide of mid-off.
Bell therefore went from four to 22 in an over, and Darren Sammy had to start chopping and changing his many bowling options.
Bell eased past his 50 on this huge playing area with a high-class four off the back foot through the off-side off Sunil Narine, before doubling his tally of career ODI hundreds in his 109th match.
He lost Trott and Ravi Bopara in near identical fashion, both edging behind as they tried to cut the off-spin of Narine and then Marlon Samuels.
Bell ensured an opener has reached three figures in each of England's last five ODI innings, only to lose Eoin Morgan - playing on to Samuels at the start of the batting powerplay - and then go himself at the end of it.
But Kieswetter maintained the momentum with some clean strikes as he scored at almost a run a ball, while Bresnan weighed in with 21 before Stuart Broad made a brisk 22 including only the second maximum of the innings.
West Indies opener Lendl Simmons chopped James Anderson down on to his stumps in the fifth over, but Smith, in place of the injured Chris Gayle, took a huge pulled six and two fours from one Steve Finn over to give the tourists' run chase early momentum in a half-century stand with Ramdin.
After Bresnan eliminated the second-wicket pair in the space of five balls, however, Smith edging a very short ball behind as he aimed to pull again and Ramdin lbw to one that nipped in slightly off the seam, Finn hit Bravo in front too.
Kieron Pollard cut Stuart Broad hard to point - where Morgan took a flying catch away to his left - and in the absence of specialist batsman Darren Bravo, who injured his groin in the field, from 127-5 the West Indies' remaining power hitters had far too much to do.
They returned from an hour-long rain break, with a revised target of 287 in 25 overs still available - and after Samuels fell to a chip to midwicket, West Indies' miserable day was soon complete as they lost their last nine wickets for 77 runs.
