Pakistan need 2 runs off last ball

Ravi Kumar to bowl the last over. And there's a wicket off the first ball! Syed Zameer is out. Can Pakistan benefit from getting Ahmad Khan back on strike? Not for long. Just a single off the 2nd ball. 

6 needed off 3 balls. Ahmad Khan back on strike, Ravi bowls. 2 runs. 4 needed off 2 balls! 2 more runs.

One last ball. 2 to get. It's Ravi to Ahmad.
