As such, the laws of the game bar substitutes from leading a side. Rizwan was spotted moving his fielders around but, in theory, any fielder can do that. Word from the team management initially was that Rizwan - the side's designated vice-captain - was the acting captain in Babar's absence, but for reviews, Sarfaraz Ahmed, the former captain who is in the XI after a long gap, was in charge. That came into play in the 53rd over, when Sarfaraz reviewed the umpire's not-out decision when Nauman Ali struck Devon Conway on the pads, and got it overturned in Pakistan's favour.
