Assuming Pakistan remain unchanged:
Umar Gul 4 overs for 20
Aamer 3 overs for 20
Abdul Razzaq 4 overs for 30
Afridi 4 overs for 25
Ajmal 4 overs for 22
Malik / Fawad 1 over for 10
^^ Plan to limit SA to 127
And that is a little realistic going on previous games... now if Umar Gul or Ajmal or Afridi has another amazing spell and gives away only 10 runs in their 4 overs then well, we're easily on top.
I don't think Pakistan need to worry about their bowling - its the batting. If Pakistan can bat first and score 150, the game is ours for the taking.
