ROSEAU (Dominica), July 29 (AFP): Half-centuries from Shakib Al Hasan and Mohammad Ashraful trumped a maiden One-day International hundred from Travis Dowlin, and inspired Bangladesh to a three-wicket victory over West Indies in the second ODI on Tuesday to take an unbeatable 2-0 lead in the series.

Shakib, the Bangladesh captain, struck 65 from 61 balls to earn the Man-of-the-Match award, and his predecessor as skipper Ashraful scored 64 from 77 balls, as the Tigers successfully chased 275 for victory in the match at Windsor Park.

Left-hander Abdur Razzak sealed the result with six balls to spare, when he top-edged a pull at a short, wide ball from Dave Bernard Jr to third man for four.

It was Bangladesh's highest successful run chase in more than 200 ODIs, and the victory followed their first-ever against West Indies by 52 runs on Sunday at the same venue.

"I can't explain the feeling," said Shakib.

"The boys have tried their best. The team has been supportive throughout the series, and so have the support staff, and we have done well.

"This was a good win though. It was much tougher. They really tested us, and they played our spinners really well."

The series concludes on Friday at Warner Park in St. Kitts, where the two sides will also contest a Twenty20 International on Sunday.
