It is not exactly him, every other batters before him were playing defensive. They not bothered to rotate the strike or even take single run at this rate they won't even reach 200 runs. They previous match against Afghanistan they played so well and today it bad or we can very bad batting by Pakistan. They would need a decent total on the scoreboard to defend it which at the moment in not looking possible for them.
Shahzaib khan 4 runs off 30 balls
Saad Baig 3 runs off 11 Balls
Ahmad Hassan 4 runs off 18 balls
Haroon Arshad 8 runs off 27
All the above actually got out while playing in defensive mode, in this case it was a mistake to face the top order batsmen in defensive mode. If the run rate would have been correct if the attacking innings was played, then the Pakistan U19 team's run target could have been 250+.
