Bangladesh Under-19 team stormed into the semifinals of the Under-19 Asia Cup with a crushing 205-run victory over Malaysia after Ahsan Al Mumin's unbeaten 152 and Tafiul Alam Tamim's seven-wicket haul at the Al Amerat Cricket Ground in Oman on Monday.

Bangladesh posted 303-8 in 50 overs after winning the toss and electing to bat, before bowling out Malaysia for just 98 in 30.5 overs.

Ahsan was the standout performer with the bat, smashing an unbeaten 152 off 133 balls, including 10 fours and six sixes.

Robiul Hasan Anik provided valuable support with 45 off 48 balls as Bangladesh recovered from an early setback to post a formidable total.

Malaysia's Nagineswaran Sathnakumaran, Syahir Asyraf and Aulga Gunawan claimed two wickets apiece.

In reply, Malaysia's batting line-up had no answer to Tafiul's devastating spell. The right-arm bowler claimed seven wickets for just 18 runs in 7.5 overs, including two maiden overs, to dismantle the opposition.

Nagineswaran offered some resistance with 50 off 81 balls but received little support from his teammates.

Rubay Islam Rizon complemented Tamim's effort with two wickets as Bangladesh completed a comprehensive victory to secure their semifinal berth. Their semifinal opponents are yet to be confirmed.
