Australia survived a Wanindu Hasaranga blitz to seal a T20I series win over Sri Lanka.

For the second time in as many days, Sri Lanka produced a disappointing batting showing in Colombo, following up 128 all out in the first game with 124-9 on Wednesday.

Charith Asalanka (39) again impressed with the bat but the Australia attack fired without the injured Mitchell Starc, as his replacement Jhye Richardson and namesake Kane Richardson accounted for seven wickets.

Australia stuttered to 64-4 in reply but were still in cruise control even when Marcus Stoinis departed to leave them 80-5 in the ninth over.

However, Hasaranga gave them hope with his final over, removing Glenn Maxwell and Ashton Agar in successive deliveries before narrowly missing out on a hat-trick.

But Matthew Wade kept his composure, scoring an unbeaten 26 to steer Australia over the line and secure an unassailable 2-0 lead in the three-match series with a three-wicket win.

Relentless Richardsons

Starc suffered a hand injury in Australia's 10-wicket win on Tuesday but his absence mattered not thanks to the efforts of Kane and Jhye Richardson.

Kane Richardson claimed 4-30 and Jhye Richardson 3-26, the latter dismissing Kusal Mendis (36) hit wicket and removing all-rounder Hasaranga (12) in the penultimate over.

Wow-nindu

Hasaranga was 0-27 for his two overs in the first game but bounced back in style with 4-33.

He looked to be turning the game in Sri Lanka's favour in the 12th over, deceiving Maxwell (19) with a googly and then bowling Agar through the gate. Hasaranga came agonisingly close to drawing an outside edge from Jhye Richardson, who denied him a hat-trick.
