Rashid Khan celebrated his 20th birthday by taking 2-13 and making an unbeaten half-century in Afghanistan's 136-run Asia Cup win over Bangladesh.

Though both nations were already through to the semi-finals, Afghanistan, who face Pakistan rather than India in the Super Four stage, recorded their second big win of the group stage.

Afghanistan, for whom Hashmatullah Shahidi (58) top-scored, were 160-7 when Rashid (57 not out) and Gulbadin Naib (42 not out) came together to put on an unbroken 95-run stand in 9.1 overs to lift their nation to 255-7 by the innings' end.

Bangladesh came up well short in their reply, as Rashid accounted for Shakib Al Hasan (32) and Mahmudullah (27) in an effort that ended 119 all out inside 43 overs.

"I'm really happy with my performance and the best thing was I performed with both bat and ball," Rashid said at the post-match presentation.

"My main focus was to bat until the end and I think our preparation was good to play until the end."

Rashid's 57 came from just 32 balls and he made eight fours as well as the innings' only maximum, while his 2-13 with the ball came from nine overs, three of which were maidens.

Gulbadin, whose partnership with Rashid was a national record for the eighth wicket in one-day internationals, also impressed with the ball, returning figures of 2-30 from his six overs.
