A century on debut from Michael Lumb proved in vain as England lost the first ODI against the West Indies by 15 runs in Antigua.
Chasing the hosts' 269-6, England's opening partnership of Lumb and Moeen Ali (44) put on 96 for the first wicket.
But once Lumb was dismissed for 109 from 117 balls with the total on 180-2, wickets fell regularly as the required rate spiralled and West Indies eventually held out for a fairly comfortable win.
Earlier, Dwayne Bravo made 87 not out, Lendl Simmons 65 and Darren Sammy 61 from 36 balls at the death to lift their side to a competitive total after they had slumped to 45-4 in the 16th over.
The England openers appeared to have put their side on course for victory despite Moeen chipping a catch to long on off Dwayne Smith and Luke Wright mustering only a single before pulling his ninth ball straight to midwicket off Sammy.
Lumb stayed the course until the 37th over, his trademark powerful strokeplay centring on drives down the ground and flashes through the off side and his 109-ball hundred containing seven fours and two sixes.
He became the ninth batsman in ODI history to make a century on debut, and just the second for England.
But after Lumb carved a catch to cover off Ravi Rampaul, England's middle order failed to materialise.
The introduction of Sunil Narine's unconventional off-breaks was too much for Ben Stokes, bowled round his legs sweeping, and Joe Root, who gloved a catch behind trying a similar shot.
Jos Buttler holed out in the off-side ring and, in his 100th ODI, Ravi Bopara could not quite come to terms with requirements as the home seamers took the pace off the ball.
The Windies were put in and spooked by early spin, but finished with a flourish thanks to Bravo and then Sammy's whirlwind 50 from only 33 deliveries.
Sammy hit five fours and four sixes as 116 runs were plundered in the last 10 overs.
By contrast, England had made all the early running.
The experiment of opening the bowling with Root worked a treat as the part-time off-spinner's first spell read 5-1-13-1.
James Tredwell was then a like-for-like but frontline replacement for Root at the pavilion end, and he too soon struck - as did first-change Tim Bresnan (3-68).
Smith hit Root for a towering six over long off in his second over, but otherwise the Windies could not get started.
Kieran Powell tried to drive Root on the up but fell to a brilliant diving catch by Chris Jordan at short cover.
It took Tredwell only three deliveries to see off West Indies' other opener, Smith edging on to his pad and wicketkeeper Buttler scampering round to take another diving catch in the leg side.
Kirk Edwards did not convince and eventually missed an attempted drive at Bresnan and was bowled off-stump.
When Moeen turned one from round the wicket to make Darren Bravo his first international victim, lbw, the hosts appeared to be in danger of faltering permanently.
But their captain and Simmons had other ideas in a crucial fifth-wicket partnership.
Dwayne Bravo took 36 balls to reach double figures and Simmons' cut for four off Tredwell was the only boundary in almost 20 overs.
It was a period of necessary caution, but the powerplay brought 41 runs and the wicket of only Simmons - backing away against Bresnan to try to beat the off-side ring but managing only to loop a low catch into the wind.
If that was not a percentage shot, almost all of Bravo's were in a 74-ball 50 which contained just three fours.
As Stuart Broad restricted himself to only six overs, Jordan's line struggled badly in the cross-wind.
He ended up bowling an extra over in wides and Root's ninth and final over cost 23, as some typically robust hitting from Sammy ensured England would have to bat very well after all.
Lumb did just that, but his more experienced teammates could not follow the rookie's example.
