Sunday, Australia took control of their five-match Twenty20 series after late fireworks from Sri Lanka forced their second match in Sydney to a rare super over after it ended in a tie.
Despite his side's struggles in the run chase during Friday's 20-run setback, Sri Lanka captain Dasun Shanaka won the toss and bowled for the second game in a row.
After Josh Inglis' 48 boosted Australia’s reach 164 for six, the Sri Lankan top order failed to fire once more.
Pathum Nissanka's 73 and Shanaka's 34 off 19 balls pushed the game to the wire.
Sri Lanka needed 12 points off the last three balls to win with Marcus Stoinis bowling. Dushmantha Chameera hit a four to tie the match and send it to a nail-biting super over. Mahesh Theekshana hit a six, then a single before Dushmantha Chameera hit a four to tie the match and send it to a super over.
With Shanaka and Dinesh Chandimal in the middle, Australia's Josh Hazlewood delivered the over. Chandimal was run out after two dot balls, and Sri Lanka only scored five runs.
With Glenn Maxwell and Stoinis hitting the target off three balls from spinner Wanindu Hasaranga, Australia needed six to win.
"It's great to win, but we were pretty careless overall, and we might have gone with one today," captain Aaron Finch said. "We bowled some great overs and some poor overs. However, the fielding was poor."
Hazlewood had already struck in the first over, removing Danushka Gunathilaka for a golden duck, caught at cover by Ben McDermott.
Sri Lanka was in serious trouble when Hazlewood removed Avishka Fernando for five in his following over, and Pat Cummins bowled Charith Asalanka without scoring.
Chandimal and Nissanka knuckled down after being reduced to 25 for three after five overs, taking them to 64 for three at the halfway mark when Chandimal was bowled for 19 by leg spinner Adam Zampa.
Shanaka was called to the wicket and hit some massive shots, putting up 39 in four overs with Nissanka before being run out by Steve Smith after a 50-meter throw.
Nissanka led his team to a 19-over total on the last over. Before Theekshana and Chameera sent it to the super over, he was outgoing for a boundary.
The character was shown by the guys "Shanaka stated. "When these kids get to the middle, they get right into the fight, which is a good sign. I'm very pleased with the performance."
Inglis, who came in when opener McDermott was out for 18, had five boundaries in his 48 innings.
