Pakistan clinched the last semi-final berth at the Under-19 World Cup by beating Bangladesh by five runs in a low-scoring thriller on Saturday. India will now face South Africa in the first semi-final on February 6 while Pakistan will play Australia on February 8, in Benoni.

Bangladesh's dreams of an Under-19 World Cup encore in South Africa - they won the title here in 2020 - came crashing down in the most heartbreaking fashion in Benoni.

Pakistan's hero was Ubaid Shah, the younger brother of pace sensational Naseem Shah. Bowling with fire, intensity and raw pace that hustled Bangladesh's batting line-up on a hot and dry day, Ubaid finished with figures of 5 for 44 as Pakistan sensationally defended 155 to win by five runs.

But until 30 minutes prior to the dramatic ending, Ubaid was left wondering if he'd dropped the cup. With Bangladesh needing 37 with four wickets in hand, Ubaid put down an absolute sitter at fine leg to reprieve Mohammad Shihad James, Bangladesh's last recognised batter for 24. However, Ubaid bounced back to dismiss him in the very next over with a superb lifter that James nicked to the wicketkeeper to trigger wild celebrations.

Rohanat Doullah Borson, who earlier in the day picked up 4 for 24 to restrict Pakistan to a chaseble total, then came up with an impressive unbeaten 21 to take Bangladesh within touching distance, before Mohammad Zeeshan sent Pakistan into delirium with the final wicket of Maruf Mridha.

Pakistan had done the unthinkable, clinching a game from the clutches of defeat in a manner reminiscent of their run to a famous title win in the 2006 final against India at the R Premadasa Stadium. That day it was Anwar Ali who swung India's famed top order out in defense of a modest 109. On Saturday, Ubaid was firmly front and centre of an inspired defence.

Their victory in the end may have been dramatic, but Pakistan were lackadaisical for large parts. Five batters got into double figures, but none carried on getting more than Arafat Mihnas' 34 lower down the order.
