Left-arm pacer Sheldon Cottrell delivered a career-best 4-28 before Shai Hope struck a half-century as Windies crushed Bangladesh by eight wickets in their Twenty20 series opener.
Windies raced to 130-2 in just 10.5 overs after Cottrell and his fellow pacers bowled out Bangladesh for 129 runs in Sylhet.
Bangladesh skipper Shakib Al Hasan scored 61 off 43 balls for the home side but could not stave off a thumping defeat.
Hope accelerated the Windies' run chase with 55 off 23 balls that included six sixes and three fours.
Victory never looked in doubt as he struck spinner Mehidy Hasan for three sixes and a four in just the second over of the innings, yielding 23 runs.
Spinner Mahmudullah Riyad dismissed Hope after medium pacer Mohammad Saifuddin broke a 51-run opening stand with Evin Lewis, who fell for 18.
But Nicholas Pooran and Keemo Paul ensured West Indies cruised to their target, with quickfire innings of 23 and 28 respectively.
