When play began two hours late, seamer Matthew Forde claimed three wickets on his international debut as England fell to 49-5.
After another rain delay, England recovered to post 206-9 from 40 overs thanks to Ben Duckett’s 71.
A second deluge reduced West Indies’ goal to 188 from 34 overs, and they appeared to be on track for a comfortable victory thanks to Keacy Carty’s controlled half-century.
England, on the other hand, fought back to set up a tense finish, with Will Jacks claiming 3-22 as the spinners did the damage.
The game appeared to be going to the wire until one costly over from the previously excellent Gus Atkinson shifted the game significantly in West Indies’ favor, and Romario Shepherd, who finished unbeaten on 41 from 28 balls, sealed the win with 14 balls to spare.
The West Indies won the ODI series 2-1 and will be celebrating their first home series victory over England in the format since 1998.
The two teams will now prepare for the five-match T20 series, which will begin on Tuesday in Barbados.
West Indies upset England in Barbados, and Duckett advances his case to become an ODI fixture.
In action: Ben Duckett
Ben Duckett averages nearly 40 in 11 one-day internationals for England.
England entered this series with a much-changed squad following their World Cup setback, and with Jos Buttler’s team not slated to play another 50-over match until September 2024, this was many of the new-look team’s last chance to impress for quite some time.
While the remainder of the top order struggled as the West Indies took advantage of the benign bowling conditions early on, Duckett proved his case for a regular spot in the one-day team.
