Having beaten New Zealand and Pakistan in earlier encounters, the Junior Tigers must have had run into complacency as they were reduced to 81-4 after being put into bat.

It was the third occasion the top-order failed to live up to their billing and it could have been worse when captain Mushfiqur Rahim was bowled on 11 with the total on 108, only to be let off the hook by the umpire who called a no-ball.

Fresh from his match winning 46 in a four-wicket victory against Pakistan on the previous day, Rahim went on to score 64 off 80 balls before Bangladesh were bowled out for 255 in 49.4 overs.

Ugandan occasional bowler Ronald Ssemanda, whose overstepping gave Rahim a new lease of life, returned to dismiss the Bangladesh captain but not before the wicketkeeper-batsman with one Test-match experience had struck half a dozen boundaries.

Rahim was adjudged man-of-the-match while Ssemanda finished with an impressive 4-43 despite poor efforts from his teammates on the field.

Opener Tamim Iqbal, not among the runs in the last two games, made a sedate 39 off 54 balls while newcomer Ishraq Sonnet blasted three fours and six in a cameo 25-ball 37 before being the last man out.

Later, Sonnet ripped through the Ugandan top order with 3-26 from a 5-over spell as the weakest nation of the 16-team tournament were skittled out for 84. Arthur Kyobe was the only player to reach double figures apart from 32 extras.

In the day's other matches, Australia survived a hiccup to beat USA by four wickets and become Group B champions while Namibia beat Scotland by seven wickets and Nepal defeated Ireland by 60 runs.

Bangladesh coach Allister de Winter later told CricInfo that he was satisfied with the performance but admitted the start had been sloppy.

"We weren't too happy with what happened early, we wanted to make sure that we respected the opposition and I don't think we respected their style of play as much as we should have," said de Winter.

"They bowled quite well in the first hour and we paid the price with a few early wickets, but it has been the bottom of our order that has saved us more than once. We don't want to have to rely on that going into the Super League."

Bangladesh now wait and see who they will face in the Super League quarterfinals, either England or Zimbabwe, but on current form they will fear no-one.

"We've played well against both sides and are just conscious of sticking to our own game plans," he added.
