David Warner and Steve Smith each smashed half-centuries as Australia hammered Sri Lanka by nine wickets to win the second Twenty20 in Brisbane on Wednesday and wrap up the series.

It was another massive wake-up call for the Sri Lankans, who arrived in Australia on the back of a 3-0 series win against Pakistan but have now been outplayed twice, after being crushed by 134 runs in Adelaide on Sunday.

They must now regroup for the third and final match in Melbourne tomorrow.

Warner and Smith came together after Aaron Finch was caught down the leg side off Lasith Malinga for a golden duck, and the pair produced a batting masterclass.

Warner was unbeaten on 60 and Smith not out 53.

Chasing 118 to win after Sri Lanka were restricted to 117 all out off 19 overs, they reached their target with 42 balls to spare.

“The bowlers did a terrific job, we bowled in the right areas and created chances and restricted them to 117, which wasn’t enough on this wicket,” said Smith.

“It’s nice and easy batting at the other end from Davy,” he added.

“He’s doing a terrific job. Played beautifully the other day and backed it up tonight as well.”

There was nothing the Sri Lankan bowlers could do against such quality batsmen, who were never troubled.

“It’s a tough side and I think with this kind of batting line-up our score wasn’t enough,” said Sri Lanka skipper Malinga.

“We didn’t get the score we expected and the batsmen will have to be more responsible. Shot selection is not that great and we didn’t get any partnerships in the middle overs.”
