Fast bowler Rizwanullah claimed five wickets before openers Hayam Khan and Usman Khan struck half-centuries as defending champions Pakistan stormed into the ACC Under-19 Asia Cup final with a nine-wicket victory over Bangladesh on Thursday. Pakistan chased down a modest target of 139 in just 21.5 overs at the Al Amerat Cricket Ground, losing only one wicket to secure their place in Saturday's final. They will face the winner of Thursday's second semi-final between Afghanistan and India. Rizwanullah led Pakistan's bowling attack with figures of 5-30 from eight overs as Bangladesh were dismissed for 138 in 31.4 overs after being put under pressure by the defending champions. Opener Abdullah Al Muhi offered the strongest resistance, scoring 50 off 45 deliveries, including four boundaries and two sixes. Rakibul Hossan contributed 26 from 39 balls, while All Rafi added 20 off 22 deliveries. Bangladesh captain Farid Hasan managed 17, but the rest of the batting line-up struggled to build partnerships against Pakistan's disciplined attack. Mohammad Sayyam took one wicket, while Ali Raza, Hasnain Abbas Dar and Ahmed Hussain also claimed a wicket each to wrap up the Bangladesh innings. Pakistan made light work of the chase, with Usman and Hayam putting together a commanding opening partnership that effectively settled the contest. Hayam struck 69 from 72 balls, hitting eight fours and a six before he was dismissed, leaving Pakistan within touching distance of victory. Usman remained unbeaten on 64 from 54 deliveries, including seven fours and two sixes, while Abdul Qadir finished on eight not out as Pakistan completed the chase comfortably. The comprehensive victory kept Pakistan's title defence on course and extended their impressive run in the tournament. The defending champions will now have two days to prepare for the final on November 14, where they will look to retain the continental crown.
