David Warner scored his first international century since serving a year-long ban for his part in the ball-tampering scandal in Australia’s tense 41-run World Cup victory over Pakistan.

Warner, transformed from the man who struggled in Sunday’s defeat by India, busied his way to 107.

With captain Aaron Finch also clubbing 82, Australia should have posted more than their 307 all out, only to lose their last six wickets for 30 runs thanks mainly to Mohammad Amir’s 5-30.
