Off-spinner Sohag Gazi made a memorable ony-day debut to help Bangladesh crush West Indies by seven wickets with 58 balls to spare in the opening game of the five-match series in Khulna on Friday.
Gazi claimed four wickets for 29 runs as he and spin colleague Abdur Razzak (3-39) ran through the West Indies batting order which failed to justify their decision to bat first and folded for 199 runs in 46.5 overs.
Opener Tamim Iqbal (58) scored his fifth consecutive one-day half century, while top order batsmen Anamul Haq (41) and Naeem Islam (50 not out) also contributed as Bangladesh lost three wickets before comfortably overwhelming the target to go 1-0 up in the series.
Tamim set the tone for a successful chase with a 88-run opening stand with Anamul, one of the four debutants Bangladesh fielded in the game.
Tamim's 58 came off 51 balls with eight fours and two sixes before Sunil Narine had him caught by Kieran Pollard at backward point.
Anamul survived some anxious moments before growing in confidence but fell short of his maiden half-century.
Naeem Islam added 45 runs with birthday boy Nasir Hossain (28) for third wicket to slam the door on West Indies.
Earlier, the visitors got off to a positive start with the openers raising 48 runs but once Mashrafe Mortaza trapped Lendl Simmons (13) lbw, West Indies batting order simply came unstuck.
Gazi delighted the packed holiday crowd at the Sheikh Abu Naser Stadium by removing the dangerous Chris Gayle (35) with his second ball with Tamim leaping high on long on boundary to take a spectacular catch.
Gazi, who took nine wickets in his test debut earlier this month, struck another crucial blow when he removed Marlon Samuels for a duck in his next over before left-arm spinner Razzak joined the party.
To make it worse for the visitors, Darren Bravo (35) got run out as Bangladesh took control of the match.
Down the order, Sunil Narine (36) and Ravi Rampaul (25) added 57 runs for the ninth wicket to give the West Indies innings some respectability but it was not enough in the end.
Gazi added two more wickets to his collection for an impressive figure which earned him the player of the match award.
Both the teams return on Sunday for the second one dayer at the same venue.
