Bangladesh have scored a first win on their tour of the West Indies, a six-wicket victory in the first one-day international in Guyana. The tourists won the toss on Sunday at Providence Stadium and chose to bowl in a match reduced to 41 overs per innings because of a wet outfield. The West Indies struggled to get going and posted 9-149, with No.3 Shamarh Brooks leading the scoring with a 66-ball 33. Tailenders Anderson Phillip (21 not out) and Jayden Seales (16no) refused to give up the final wicket, adding 39 runs, with Phillip hitting his team's only six of the innings. Shoriful Islam took 4-34 and Mehidy Hasan Miraz 3-36 in the pick of the Bangladesh bowlers. The tourists reached the target with 55 balls to spare, scoring 4-151 in 31.5 overs. Mohammad Mahmudullah top-scored with an unbeaten 41 off 69 deliveries, and Najmul Hossain Shanto hit a 46-ball 37. Spinner Gudakesh Motie was economical with a return of 1-18 from nine overs. The second ODI in the three-match series is on Wednesday at the same venue. West Indies won both Test matches and the Twenty20 series 2-0. Australian Associated Press
