The right-arm spinner Mehidy Hasan Miraz bagged four for 25 in 9.4 overs, his best bowling figure in ODI. His previous best was taking four for 29 runs. Mustafizur Rahman and Shakib Al Hasan took two wickets each.
Unlike the first match of the series, Jason Mohammed, the stand-in captain of the West Indies, won the toss and opted to bat first. His decision came as a surprise as the wicket, which was used in the first game as well, was not a good one for the batsmen.
However, they did not lose their first wicket in the second over as they did in the first game. Despite that, they failed to take control of the game with the bat.
Mustafizur brought the first breakthrough for the hosts, removing Sunil Ambris in the fifth over for 6. The debutant Kjorn Ottley and wicketkeeper-batsman Joshua Da Silva faced 50 balls in the second wicket stand to post only 26 runs.

Mehidy took the second wicket removing the debutant Ottley for 24. It was a length ball at the outside off stump. And Ottley hit the ball hard only to be caught by Tamim Iqbal at the extra cover area.
Mehidy took the next wicket as well, dismissing Joshua Da Silva for 5 off 22 balls. This time it was a length ball again, and Da Silva defended, thinking the ball was coming into him. But the ball was straight and dislodged his stumps.
When the West Indies were struggling at 37 for three, Shakib bowled Ande McCarthy out for three and Najmul Hossain Shanto displayed a wonderful fielding effort to trap Kyle Mayers run-out for a duck.
In the sixth wicket stand, Mohammed and Nkrumah Bonner added 26 runs. When the partnership was getting big, Hasan Mahmud came to the scene and removed Booner for 20 off 25.
That was a length delivery, and Booner went to cut it away but only managed an inside edge. The ball came in kissing his bat and shattered his stumps.

Mohammed was looking forward to making a good partnership with Rovman Powell, but Shakib removed him off an arm ball. Mohammed applied for a DRS, thinking of having an inside edge, but the TV replay showed there was no connection between ball and bat.
Before being hunted by a stumping effort of Mushfiqur Rahim, Rovman posted 40, highest in the innings. He got support from Alzarri Joseph, 17, and Akeal Hosein, 12*.
In the ninth wicket stand, Rovman and Joseph added 32 runs, their highest stand in the match. In the last wicket stand, Rovman and Akeal faced 40 balls to post a total of 28.
Riding on the last two partnerships of the innings, the West Indies got close to 150. They eventually, managed to score for 148 for 10 in 43.3 overs.
