West Indies 325 for 6 (Jangoo 104*, Carty 95, Rishad 2-69) beat Bangladesh 321 for 5 (Mahmudullah 84*, Mehidy 77, Soumya 73, Jaker 62*, A Joseph 2-43) by four wickets

Brandon King picked up where he had left off in the second ODI, cracking two fours and a six off Nasum Ahmed in the second over of the chase. His innings, however, was cut short in the same over after a mix-up with his opening partner Alick Athanaze over a non-existent run. Athanaze himself did not last long, getting yorked by Nasum in his next over.

Carty, though, was steady at the other end, already having struck two fours. Afif dropped him on 22 before Carty went after the Bangladesh spinners in the middle overs. He struck Rishad Hossain for consecutive fours in the 18th over, before hammering Mehidy Hasan Miraz for a six and a four in the 21st over. Jangoo hit Nasum for three fours in a short span before lofting Afif for his first six.

It was in the 34th over that Bangladesh, perhaps, let the game slip. Jangoo had miscued one off Rishad, only to see substitute fielder Parvez Hossain Emon drop the chance while running back ffrom mid-off. Rishad did dismiss Carty next ball, with Soumya taking a low catch at point, but Jangoo's miss came back to haunt them.

Immediately after Roston Chase's dismissal, Jangoo slogged Mehidy for his second six, before Motie and Jangoo struck Mahmud for a six each in the 43rd over. They struck one four each in the following over bowled by Taskin, before the pair completed the chase.

The day could have belonged to Bangladesh given how they batted. After a disastrous start, having lost both Tanzid Hasan and Litton Das in the third over to be reduced to 9 for 2, Soumya and Mehidy resurrected the innings with a 136-run stand for the third wicket. Alzarri Joseph hurried Tanzid with a bouncer with the left-hander top-edging a pull. Litton's horror run in ODIs continued when he edged a wide one to King at first slip.

Mehidy was positive from the outset, hitting five boundaries in the powerplay. Soumya, who was dropped on nought, opened up after the powerplay. He played the upper-cut against Romario Shepherd for a six, before pasting Chase and Motie for a six each in consecutive overs.

Six overs after Soumya's dismissal, Rutherford's accurate throw from point found Mehidy short at the striker's end as he fell for 77 off 73 balls. Rutherford then had Afif Hossain caught at the midwicket boundary for 15, as Bangladesh again lost two wickets in quick succession.

But Jaker and Mahmudullah dominated the end overs. After having added 96 in the first ODI, they bettered it this time. After Jaker struck his first two fours, Mahmudullah crashed Motie down the ground for his first six, before hitting Chase for his second, over long-off.

Jaker joined the party when he slammed Shepherd over cover and then Mahmudullah dragged Rutherford from outside off over square-leg for six. Bangladesh scored 59 runs in the last four overs to push their total past 320, but it was not enough on the day.
