Warner leads Australia to T20 clean-sweep over Sri Lanka

Australia cruised past Sri Lanka to clean-sweep their three-match Twenty20 series Friday, with an in-form David Warner grinding out a third successive half-century in the seven wicket win.

The home team have been dominant throughout, winning by 134 runs in Adelaide and by nine wickets with seven overs to spare in Brisbane ahead of the clash in Melbourne.

Sri Lanka's batting had been insipid until now, but they finally posted a competitive score of 142 for six, with Kusal Perera hitting 57.

However their bowlers, led by Lasith Malinga, have been no match for a quality Australian batting line-up, spearheaded by Warner who has now scored 217 in three innings without losing his wicket.

"It was pretty clinical once we got into a routine," said Australia captain Aaron Finch.

"The way the bowlers set it up for us over the last two games, it was outstanding.

"Every game is a different challenge and a different surface, so it's important to bring in your best, in terms of preparation and mental side of the game too."
