Dhaka: Leg-spinner Devendra Bishoo grabbed 5-90 as the West Indies trounced Bangladesh by 229 runs in the second and final Test in Dhaka on Wednesday to wrap up the series 1-0.
Bangladesh, who were set an improbable victory target of 508 runs, were shot out for 278 soon after lunch on the fifth day at the Sher-e-Bangla stadium.
Bishoo, the Guyanese bowler who turns 26 on Sunday, returned with career-best figures in only his seventh Test and skipper Darren Sammy chipped in with 2-19 to rout the hosts.
Devendra Bishoo took five wickets on Wednesday as West Indies beat Bangladesh by 229 runs in the second Test at Dhaka to clinch the two-match series 1-0.
The emphatic win after the drawn first match in Chittagong provided a massive morale-booster for Sammy's men, who begin a three-Test series in India on Sunday.
Bangladesh, resuming at the overnight score of 164-3, lost the crucial wickets of opener Tamim Iqbal, skipper Mushfiqur Rahim and Shakib Al Hasan in the morning session. Tamim, Bangladesh's main batting hope who was unbeaten on 82, added just one more run when he was caught in the slips off Bishoo in the day's third over. The left-hander's 83 contained eight boundaries and a six.
Shakib and Rahim raised visions of a Bangladesh fightback when they put on 88 runs for the fifth wicket, before both batsmen fell in the space of four runs.
Shakib made 55 when he tried to steer Sammy to third man, but only managed to sky a catch to Shivnarine Chanderpaul running back from the slip region. Rahim took his overnight score of 33 to 69 when he was bowled by a superb delivery from Bishoo that spun in sharply from leg to clip the off-stump.
Bishoo struck twice in the first over after lunch, trapping Nasir Hossain leg-before and having Suhrawadi Shuvo caught by Sammy. Fast bowler Kemar Roach sealed the win by bowling last man Rubel Hossain.
