West Indies cruised to a comfortable seven-wicket victory over Bangladesh, securing their first bilateral ODI series win against the visitors in 10 years.
The win was powered by a career-best bowling performance from Jayden Seales, who claimed four wickets for 22 runs.
His outstanding spell set the tone as West Indies bowled out Bangladesh for 227 before comfortably chasing down the target with 13.1 overs to spare.
Opting to bowl first in St. Kitts, the decision proved to be a masterstroke as Seales made early inroads.
He struck thrice in his opening spell, sending Soumya Sarkar, Litton Das and Bangladesh captain Mehidy Hasan Miraz back to the pavilion cheaply inside the powerplay.
Despite a counterattack from Tanzid Hasan, who scored a brisk 46 off 33 balls, Bangladesh were left reeling at 64/4 in the 11th over.
A brief recovery followed as Mahmudullah and Afif Hossain combined for a 36-run partnership.
However, the West Indies spinners continued to dominate, with Gudakesh Motie claiming two key wickets to leave Bangladesh struggling at 104/6 in the 21st over.
Mahmudullah then found a steady partner in Tanzim Hasan Sakib and the pair forged a gritty 92-run stand for the eighth wicket, rescuing their team from further collapse.
Mahmudullah's half-century came off 84 balls, and together with Sakib, took Bangladesh past the 200-run mark.
However, the breakthrough came when Roston Chase took a brilliant return catch to dismiss Sakib, who fell just five runs short of a well-deserved half-century.
Seales returned to dismiss Mahmudullah soon after, and Shoriful Islam's late cameo of 15 runs helped Bangladesh reach a total of 227 before they were bowled out in the 46th over.
In reply, the West Indies got off to a strong start, with Brandon King and Evin Lewis putting on 109 for the first wicket.
King took the aggressive route early on, while Lewis, initially struggling at the crease, found his rhythm with a flurry of boundaries.
Lewis took on Sakib with three consecutive boundaries including a six in the ninth over to bring up the team's fifty, and by the end of the powerplay, West Indies were well-placed at 54/0.
Lewis continued to push on, hitting a couple of sixes off Mehidy, but was dismissed for 49 when Rishad Hossain had him caught and bowled.
King, who had brought up a 52-ball fifty, remained firm at the crease, anchoring the chase as Keacy Carty joined him for a 66-run partnership.
Carty was the core aggressor of the stand, hitting seven boundaries in his 47-ball knock before falling five runs short of a half-century.
With just 31 runs needed for victory, Sherfane Rutherford provided the finishing touch with an explosive cameo.
His quick-fire 24 off 15 balls, including two sixes and a four, sealed the win for West Indies, who finished with 228/3 and wrapped up the series with more than 13 overs to spare.
