His keeping can be carbon monoxide at times, and he can get a surplus of oxygen supply to his brain at times due to which he throws his wicket away frequently (which he did today as well but Wade missed the stumping), but the quick runs that he scores is very useful.
I'm sure Misbah is pulling his hair out right now because Sarfraz's strike rate is not below 50. I hope he doesn't get fined for it.
Another way of looking at it is that Australia also lost 6 for 92 today before the last wicket partnership. So, Pakistan's performance is not that horrific in comparison
