Brandon King and Keacy Carty blazed centuries to help the West Indies crush England by eight wickets in the third and final ODI, in Bridgetown.
Chasing 264 to win, opener King (102) and Carty (128 not out) put on 209 runs for the second wicket to seal the win and the three-match series 2-1. Evin Lewis was dismissed for 19.
West Indies had won the first ODI by eight wickets, while England won the second by five wickets.
Put into bat, England lost half their side for 94 runs. Opener Phil Salt (74) was the only top-order batter to be among runs, while Dan Mousley (57), Sam Curran (40), Jofra Archer (38) and Jamie Overton (32) played important knocks down the order to help England to a respectable total.
Pacer Matthew Forde took 3/35, while fellow fast-bowlers Alzarri Joseph and Romario Shepherd scapled two wickets each.

But, the West Indies team's joy was marred by Joseph leaving the pitch after a disagreement with skipper Shai Hope. Ahead of the fourth over of the England innings, Joseph and Hope were seen having a heated discussion over a field placement. The pacer went on to dismiss Jordan Cox (1) off the fourth delivery, but stormed off the ground soon after his over.
Head coach Daren Sammy had to step in to cool things down. Joseph returned to the field an over later, but came on to bowl only in the 12th over. He bowled two more overs, but left the field again misfields off his bowling, and then came back to finish his quota of 10 overs, giving away 45 runs.
Sammy did not mince words later when asked about the incident. "Behaviour like that is unacceptable on my cricket field," Sammy told TalkSPORT. "We will be friend, but in the culture I am trying to build, that's unacceptable. We will definitely have a chat about that."
The five-match T20 series between the West Indies and England begins on Saturday.
