Pallekele: Captain David Warner became the first Australian to hit a one-day international century in Sri Lanka as he led his team to a five-wicket victory Sunday — with 42 balls remaining — and a 4-1 win in the series.

Sri Lanka opted to bat after winning the toss and was bowled out for 195 in 40.2 overs.

Australia was at 25-2 in its chase but Warner held the innings together, sharing 132 runs for the third wicket with George Bailey, who made 44.

Australia reached 199-5 at the end of the 43rd over with a boundary from John Hastings.

‘Good to get a milestone but the credit goes to our bowlers,’ Warner said. ‘It was always going to be a challenge coming here and facing that new ball ... (Bailey) has been a rock in the middle allowing us to bat around him.’

Bailey was named player of the series with 270 runs in five matches with an average of 67.5.

Sri Lankan bowlers started aggressively, and spinner Dilruwan Perera struck in the fourth over, having Matthew Wade (3) caught behind with the total on 11.

Usman Khawaja (6) failed again when he tried to play Dilruwan Perera against the turn and skied the ball for a catch to Danushka Gunathilaka.

But Warner and Bailey weathered the difficult period, taking time to adjust to the pitch before opening up to score runs.

Their partnership took 161 deliveries before Bailey was out in the 33rd over, trapped lbw by Dilruwan Perera.

Warner’s 106 off 126 balls was a return to form for the captain — after just 38 runs in the last four games. He was caught and bowled by off spinner Dhananjaya de Silva.

Dilruwan Perera returned 3-51.

Sri Lanka stand-in captain Dinesh Chandimal blamed poor batting for the defeat.

‘We are really disappointed with the batting unit throughout the series,’ Chandimal said. ‘With experienced guys we have good youngsters, but they have to learn if they get a start they have to bat longer. It makes it easier for others.’

Earlier, Australian fast bowler Mitchell Starc took 3-40 while spinners Travis Head and Adam Zampa took two wickets each to help Australia dismiss Sri Lanka with more than nine overs remaining.

Chandimal elected to bat first and had his side’s best opening partnership of the series from de Silva and Gunathilaka, who shared 73 runs.

In the 14th over, de Silva (34) was caught by Starc at mid-on off James Faulkner. In the next over, Zampa bowled Gunathilaka (39) and in the over that followed Chandimal was caught behind off Starc for 33, leaving Sri Lanka 78-3.

Kusal Mendis reached 33 and shared 43 runs for the fourth wicket with Upul Tharanga before being caught behind off fast bowler Hastings.

Tharanga, who had been called up to bolster the middle in the absence of injured regular captain Angelo Mathews, made just 15 before being caught at cover by Zampa off Head.

Kusal Perera reviewed an lbw decision but the television umpire upheld his dismissal despite television replays appearing to show an inside edge.

Sri Lanka lost its last seven wickets for 74 runs.

Starc finished with 3-40, Head had 2-22 and Zampa returned 2-43.
