Australia batsman David Warner was a happy man after returning to something like his best form with a century to lead his team to victory over Pakistan at the Cricket World Cup on Wednesday.

Warner, recently back on the side after serving a 12-month suspension for his role in last year's ball-tampering scandal, had struggled for fluency in the early games of the tournament.

"To come out here play the way I know I can play was awesome," the 32-year-old left-hander told a news conference. "I was elated."
