West Indies recovered from 45-4 to post a total of 269-6 in the first one-dayer of the three-match series against England in Antigua.
Skipper Dwayne Bravo led the home side's recovery with an unbeaten 87, including sharing a fifth-wicket stand of 108 with Lendl Simmons (65).
However it was the arrival of Darren Sammy to the crease that saw the momentum really swing in the home side's favour - the former captain belted 61 from just 35 deliveries, including hitting four sixes and five fours.
Together with Bravo he helped add 116 runs in the final 10 overs, 85 of which came from the last 30 balls the duo faced as they launched a late onslaught.
All this was in stark contrast to the first half of West Indies' innings, as they were stifled by England's mixture of spin and seam on a slow surface.
The tourists - without Eoin Morgan and Alex Hales due to injuries - opted to open the bowling with Joe Root and the plan paid off as he picked up the first wicket, Chris Jordan taking a good catch to send back Kieran Powell (five).
It was spin that also accounted for the other home opener, Dwayne Smith caught by a diving Jos Buttler for 24 after he had edged a James Tredwell delivery into his front pad.
Tim Bresnan accounted for Kirk Edwards for 10, and when Moeen Ali, who along with Michael Lumb was handed an ODI debut for England, trapped Darren Bravo leg before for two, West Indies were in a real hole.
But Bravo and Simmons did superbly to repair the early damage before beginning to pick up the pace during a batting powerplay that yielded 41 runs, even if the latter did perish to Bresnan (3-68).
Sammy duly came in and pushed the tempo into top gear, Jordan came in for some particularly heavy punishment while Root's last over went for 21, ruining his figures somewhat as he finished with 1-47.
Surprisingly, skipper Stuart Broad only bowled six of his 10-over allocation, while neither Ben Stokes nor Ravi Bopara, playing in his 100th one-dayer for England, were called into the attack.
