Sri Lanka won the toss and elected to bat first and managed only 128-9 in 20 overs. Dhananjaya de Silva scored 62 for his maiden Twenty20 international half-century

Legspinner Adam Zampa and fast bowler James Faulkner took three wickets each for Australia.

Maxwell and captain David Warner started the Australian chase aggressively and shared 93 runs in 51 balls But from there the tourists lost six wickets for 27 runs but went over the line with 13 deliveries to spare thanks to the good opening stand. Retiring Tillakaratne Dilshan had best figures 2-8 for Sri Lanka.

Maxwell continued his superior form the first match and reached his half-century in 18 balls, the fastest by an Australian. He made an unbeaten 145 in the first match to take Australia to a 85-run win.

He was bowled by legspinner Seekkuge Prasanna off the inside edge.

Left-arm spinner Sachith Pathirana brought Sri Lanka strongly back into the game taking two wickets in the tenth over after Australia had experimented with the batting order by promoting lower order batsmen.

Moises Henriques was sent in at No. 3 but he was out for one stumped off Pathirana. Two balls later Warner (25) was out caught by Thisara Perera off Pathirana.

Dilshan took a wicket off the last ball of his international cricket when he had Matthew Wade (14) caught by Dinesh Chandimal leaving Australia 120-6.

Travis Head hit a six off Pathirana to seal victory.

Australia finishes its tour to Sri Lanka on a winning note having won the one-day international series 4-1 and winning the Twenty20 series 2-0 after losing the test series 3-0.

Captain Warner said that said playing on Sri Lankan pitches was tough but commended his players for their determination and fight to overcome the challenge.

Warner however was disappointed that his team lost wickets consistently after a good start.

“We probably saw there the lack of consistency when we lost a wicket after a good start,” Warner said.

“Something we want to keep improving on. It’s disappointing we lost five or six for 20 in eight overs in the middle after being none for 90. But obviously it is fantastic to get a win and win the series.”

Dilshan said that he is disappointed to leave the game with a loss.

“We tried our best to win the match but we were about 20 runs short; and also while bowling we gave away too many runs in the first six overs,” Dilshan said.

“It’s time to relax now. It was pressure playing for the country. Now I feel lighter.”

The International Cricket Council paid tribute to Dilshan calling him an “epitome of the modern-day cricketer with his ability to adapt.”

Dilshan is among the 11 players to have scored a century in all formats of cricket.

“Dilshan’s accomplishments across all three formats are fantastic. He started as a solid batsman but adjusted to the demands of the faster-paced game and came to be known as one of the best in ODI and T20 Internationals,” the ICC statement quoted its chief executive David Richardson as saying.

“He will be remembered for his innovative strokes and as a destructive opener. He was also a useful spin bowler and an outstanding fielder. We congratulate Dilshan for a fine career and wish him every success in the future.” Richardson said.

Dilshan leaves international cricket with 17,671 runs in 497 games across all formats. He also had 151 international wickets.

Matthew Wade will play his first Twenty20 International in seven months when he comes into the Australian side as a specialist batsman for the final match against Sri Lanka in Colombo.

Aaron Finch remains sidelined with a broken finger and with George Bailey returning home as scheduled due to family reasons, coach Darren Lehmann has been left with a bare minimum 12 players for the second and final T20 clash of the series.

“That I can give you,” Lehmann said. “We’ve only got 12 fit players as Finch is not available and George has gone home so Wade will play.”

Peter Nevill will continue to take the gloves for Australia, while Wade and Bailey were only selected to stay on for the extra matches after Finch and Chris Lynn suffered late injuries.

The only change could come to Australia’s bowling attack, with the in-form John Hastings set to return to the line-up after being left out of Australia’s opening 85-run win on Wednesday morning (AEST). All-rounder Moises Henriques, who conceded 12 runs per over in that match, could be the man to make way for Hastings.

However the fourth meeting between the two teams which takes place at Pallekele Stadium today could see a change in fortunes for the visitors who have picked themselves up very well from the 0-3 whitewash they suffered in the Test series to beat Sri Lanka pretty convincingly 4-1 in the five-match one-day international series that ended on Sunday.

Although Australia won the fifth ODI it came at a price because they lost two of their key players who make up their T20 squad. Star batsman Aaron Finch fractured his finger and Chris Lynn dislocated his shoulder to be ruled out of the two T20 internationals against Sri Lanka.

Lynn has a dislocated left shoulder suffered during a routine fielding drill before the fifth ODI and Finch was forced from the field during the Sri Lanka innings when he hurt his right index finger attempting a catch which later was confirmed as a fracture.

One-day specialists – wicket-keeper Mathew Wade and batsman George Bailey will replace them in the T20 squad.

Australia will also be strengthened by the inclusion of hard-hitting all-rounder Glenn Maxwell, a surprise omission in the ODI series. Maxwell’s last innings against Sri Lanka was a brutal 102 off 53 balls in a World Cup match at Sydney last year, an innings which Sri Lankan bowlers picked in the squad for the two T20Is will remember – Sachitra Senanayake, Seekkuge Prasanna, Thisara Perera and Tillakaratne Dilshan.

Dilshan who retired from ODIs in the third match of the series will play his final two T20Is against Australia before stepping down from that format also. His final appearance is scheduled for September 9 when Sri Lanka and Australia play the second T20I at the R Premadasa Stadium where a sell-out crowd is expected to turn up.

Dilshan is the leading run-getter for Sri Lanka in the T20I series between the two countries with 247 runs from 8 matches and is also the only batsmen from either side to score a hundred in this short format.

Certain comments the retiring veteran made at the end of the third ODI have not gone down well with some of the team members, one of whom Angelo Mathews will not be present at his farewell after a grade two tear on his right calf ruled him out of the final ODI and the two T20Is.
