The 19-year-old right-hander scored 120 in only his second one-day and built the innings with a solid 174-run partnership for the third wicket with captain Mushfiqur Rahim (79) after the hosts were sent into bat on a flat pitch.

Anamul pulled a short ball from Ravi Rampul in the 47th over to become the third youngest Bangladeshi and the eighth youngest in the world to score a century, behind countryman Tamim Iqbal and Shakib Al Hasan.

Anamul, who emerged as a serious contender for the senior team after scoring two hundreds in the ICC Junior World Cup in August, hit two sixes off Andre Russell in the 49th over before holing out in Rampaul's next.

In all he faced 145 balls and hit 13 fours and gave the innings the much-needed impetus with a sixth wicket stand of 64 with Mominul Haque (31) as the hosts scored 86 in the last 10 overs.

The Anamul-Rahim stand is the new record in all Bangladesh-West Indies one-days, beating the 146 between Ramnaresh Sarwan and Marlon Samuels in Dhaka ten years ago.

It also becomes the highest total by Bangladesh in all one-days against the West Indies, improving on 276-7 they scored in Dominica three years ago.

Bangladesh had lost Tamim Iqbal (five) and Naeem Islam (six) by the seventh over but Anamul and Rahim repaired the innings.

Paceman Ravi Rampaul was the best among the tourists, finishing with a career-best 5-49.
