Champions Trophy, Rose Bowl: West Indies 269-3 (50 overs) beat Bangladesh 131 (39.3 overs) by 138 runs
Dillon made short work of Bangladesh's top order
Paceman Merv Dillon produced the best one-day figures of his career as West Indies brushed aside Bangladesh by 138 runs in the Champions Trophy.
Dillon took 5-29 at the Rose Bowl as Bangladesh were bowled out for 131, having been set a target of 270.
Chris Gayle (99) and Wavell Hinds (82) shared a stand of 192 for West Indies as they totalled 269-3.
Brian Lara hit two sixes in his 20 off seven balls to help his side add 77 in the final 10 overs of their innings.
West Indies, the final team to begin their Trophy campaign, were below full strength with Ricardo Powell and Corey Collymore resting minor injuries.
Their absence gave Sylvester Joseph and Darren Sammy an opportunity and the latter, a member of the MCC Young Cricketers' scheme, made a positive impression with three catches and a wicket.
But the first half of the match was all about the West Indies batsmen, who punished their opponents for a series of fielding lapses.
Hinds and Gayle equalled the tournament first wicket record
Hinds, playing his first one-day international for 10 months, was dropped twice and had another stroke of luck on 28 when umpire Jeremy Lloyds failed to spot an edge and turned down Khaled Mahmud's appeal.
Gayle also benefited from a fielding lapse as Mahmud failed to hang onto a fierce caught and bowled chance when he had made 46.
Nazmul Hossain, just 16 years old, showed his promise with a tight seven-over new ball spell but Bangladesh could not separate the openers until the 40th over.
Hinds was the man to go, caught in the deep off Tapash Baisya, who also denied a Gayle a century by having him caught behind for 99.
Baisya also removed Brian Lara, who had hit two sixes in his 20 off seven balls before he was brilliantly run out by the bowler after backing up too far.
Bangladesh's reply soon became a procession as Sammy took a juggling gully catch to dismiss Javed Omar off Dillon, who followed up by bowling Nafis Iqbal and Rajin Saleh.
The Trinidadian also removed Khaled Mashud for a duck and found time to lend new ball partner Ian Bradshaw a hand by taking a catch at long leg to account for Mohammad Ashraful.
The hook shot resulted in Mohammad Ashraful's downfall
Aftab Ahmed and Mushfiqur Rahman stemmed the tide by adding 45 but they both fell for 21 in successive overs from Dwayne Bravo and Sammy.
Bradshaw put down two return catches offered in the same over by Mohammad Rafique (12), but Sammy was not in charitable mood as he hung onto an edge to give Dillon his fifth wicket.
Gayle was utilised as the fifth bowler by Lara and the off-spinner's opening delivery was obligingly lofted to substitute fielder Ryan Hinds by Baisya, who made eight.
It was then just a question of time, but Mahmud made West Indies work for their victory with 34 before Nazmul fell to Bravo's agile one-handed catch at cover with Gayle picking up his second victim.
