Bangladesh piled up only 136-6 despite a 53 ball-65 from Tamim Iqbal.
Bangladesh captain Mahmudullah Riyad regretted the batting debacle in the second T20 against Pakistan, stating that they couldn't apply themselves well which caused their nine-wicket defeat.
The heavy defeat came a day after their five-wicket loss to Pakistan in the first match, which meant they lost the three-match series.
Bangladesh piled up only 136-6 despite a 53 ball-65 from Tamim Iqbal. Pakistan however gunned down the target in just 16.4 overs thanks to half-centuries from Mohammad Hafeez and skipper Babar Azam.
"It's really disappointing to lose. We especially couldn't apply ourselves with the bat. The exception was Tamim Iqbal but we couldn't support him well," Mahmudullah said after the match.
In what turned out to be Bangladesh's must-win game in three-match series, the Tigers yet again won the toss and opted to bat first but the middle-order failed to show any resolve in batting.
Tamim held the innings together and clobbered seven fours and one six in his knock before being run-out in the 18th over. Afif Hossain made 21 off 20 while captain Mahmudullah Riyad scored 12.
Mahmudullah said they even couldn't finish off the innings well when there were enough wickets at hands. Bangladesh could score just 48 runs, losing two wickets in the last five overs.
It was a poor return considering the fact that at that time Tamim Iqbal and Mahmudullah was in the crease and both of them were well set.
While Tamim was expected to make up for his slow start at the death by playing some big shots, he was run-out by running between the wickets casually. Mahmudullah, in contrast, was undone by an express delivery by Haris Rauf.
Their dismissals in a short space effectively ended Bangladesh's route to put up a reasonable total on the board.
"We didn't finish off well, which was really disappointing as we are in a position to use the last powerplay well," Mahmudullah remarked.
He, however, said that he is not sure what Bangladesh's approach will be in the last game on Monday that is now a dead-rubber.
"Not sure yet how we'll go for the last game, maybe we'll try to play some reserves, but we need to come hard at them and win the game," he concluded.
