I think the only change should be Sunny in, and either of the 2 fast bowlers...out.
SNafees will come back, especially since he bats at # 3...and that the opposition attack is not that good. The longer the opening pair holds up, the odds of him doing better go up (maybe someone has the stats).
As for the opening...do not replace Zunaid by promoting someone up the order. That is a suicidal experiment. Just hope that he scores more than 7.
