With their fourth consecutive win Bangladesh also confirmed their place in the final. On the other hand, despite the defeat Sri Lanka were also almost certain to play the December 14 final as they already have defeated England, the third side in the meet, twice.

After deciding to bat, Bangladesh thrived on two half-centuries by Shamsur Rahman and Test cap Rahim to put up a challenging total of 253-6 in 50 overs.

Two local centurions of the tournament Tamim Iqbal and Raqibul Hasan gave Bangladesh a flying start as the opening pair added 63 runs in 8.5 overs.

But after the dismissal of Raqibul (23 off 28 balls), the home team experienced a little hiccup as they lost two more wickets for one run. Left-handed Tamim smashed 34 off 24 balls that featured six boundaries.

Shamsur Rahman, who was playing his first match of the tournament, repaired the damages featuring in a 56-run fourth wicket stand with Mehrab Hossain (21). The right-hander contributed 59 off 88 balls with four hits to the fence.

Number six Rahim struck five fours and one six in his 69-ball knock.

Weerasinghe was the most successful Sri Lanka bowler with 3-39.

In reply, Sri Lanka lost wickets at regular intervals to be bundled out for 151 in 41.1 overs with opener Soyza making the team highest 46.

New ball bowler Kamrul Islam claimed three wickets for 40 while super-sub spinner Nabil Samad and Suhrawardi Shuvo captured two wickets each for the home team.

Meanwhile, umpire Shawkatur Rahman made a mockery with the power-play during the second innings as he confused twice with wrong calls.
