Colombo: Pakistan won the toss and chose to bat first against Sri Lanka in the fourth One-Day International on Friday. 

Pace bowler Umar Gul and all-rounder Abdul Razzaq were not available for Pakistan due to injury, while opener Imran Nazir, returning to international cricket after ending his contract with the unsanctioned Indian Cricket League, took the place of Nasir Jamshed.

Sri Lanka, who lead the five-match series 3-0, made three changes, with bowlers Lasith Malinga, Malinga Bandara and Ajantha Mendis coming into the side.
