Australia, chasing a challenging 413 for victory, were bundled out for 183 after lunch as Sri Lanka, who won their last series against the visitors in 1999, took an unassailable 2-0 lead in the three-match rubber.

Veteran spinner Rangana Herath set up the win for the hosts with his maiden Test hat-trick which helped dismiss Australia for a record low of 106 in their first innings.

Australia faltered in their second outing as well after Perera, who registered his career-best figures of 6-70, sent the visitors packing in just 50.1 overs as the Sri Lankan players went into a celebratory huddle.

Overnight batsmen David Warner and skipper Steven Smith offered some resistance with their 51-run fourth wicket partnership but both of them fell to Perera’s guile.

Warner, who tried to counter attack during his 31-ball 41, was trapped lbw off a straighter Perera delivery that hit the batsman on the front pad.

Smith (30), who used his feet well against the spinners during his 58-ball stay, was the next to go as he gave away a catch at backward short leg.

Perera, who also took two wickets on Friday, then bowled Adam Voges for 28 to register his fourth five-wicket haul in 11 Test matches.

But it was Herath’s left-arm spin that did the early damage in a match dominated by Sri Lankan slow bowlers.

Herath and Perera shared four wickets between them on a chaotic second day which saw the fall of 21 wickets and put the match on the fast track.

Australia’s pace spearhead Mitchell Starc though made his presence felt on a track that offered little help to the fast bowlers with his career-best match figures of 11-94.

Sri Lanka won the first Test at Pallekele by 106 runs.
