He is bowling at the back end when pressure is on, Yesterday Islamabad required 25 on 12 balls and he bowl the very good over.
He is using his ability as per his strength in the last overs, He was never a new bowl bowler.
Which is why I mentioned yesterday was better . . on days prior, he has put inexperienced folks bowling at times when the attack is on . . He has never been a great new ball bowler but he is still miles better than the rest in his team . . should be bowling at critical times when pressure is on
