Hughes heroics hurt Sri Lanka
A century from Phil Hughes on his one-day international debut helped Australia to a 107-run win against Sri Lanka at the MCG on Friday.
Twenty-cap Test batsman Hughes, who hit 112 from 129 deliveries, became the first Australian to notch a hundred on debut in the one-day game as the home side posted 305 for five.
George Bailey added 89 in a 79-ball stay and David Hussey blasted 60 not out from 34 deliveries.
Despite losing two early wickets, Sri Lanka were in the game at 111 for two after 25 overs with Tillakaratne Dilshan, who made 51, and Dinesh Chandimal, the team's top scorer with 73, looking comfortable at the crease.
However a period of madness that saw Australia complete three run outs - two of which were direct hits - in less than five overs effectively ended the contest as Dilshan, Angelo Mathews and Lahiru Thirimanne were sent back.
Pacemen Clint McKay, a standout performer with figures of four for 33, and Mitchell Johnson mopped up the tail as Sri Lanka were eventually dismissed for 198 in front of 27,461 fans in Melbourne, giving Australia a 1-0 lead after the opener in the five-match series.
Needing more than six runs per over, the tourists made a disastrous start to their daunting run chase.
After Dilshan played and missed at three McKay deliveries in the second over - he also edged a boundary through slips in the third - Upul Tharanga was dismissed by Mitchell Starc.
Tharanga was caught by wicket-keeper Brad Haddin and Mahela Jayawardene soon followed when he edged McKay to Aaron Finch at first slip.
Dilshan continued to take risks in trademark fashion while Chandimal started off patiently before displaying his obvious talent with a series of sublime strokes.
Both batsmen jumped on anything short and hit several boundaries through point and gully and they passed 100 in the 23rd over.
Australia's spinners were not looking threatening - Xavier Doherty, Glenn Maxwell and Hussey bowled 17 overs between with them without taking a wicket - and Sri Lanka seemed right in the game.
A brilliant piece of fielding from Khawaja changed that though, as he threw down the stumps at mid-off to remove Dilshan after he risked a quick single in the 26th over.
Just four overs later, Maxwell produced a direct hit from the off side to dismiss Mathews, and from the very next ball a suicidal attempted single saw Thirimanne run out for a diamond duck.
Chandimal continued to play well but he ran out of partners before being dismissed thanks to a sublime one-handed catch from Haddin.
McKay and Johnson finished off the innings with a minimum of fuss as the tourists were bowled out with exactly 10 overs remaining.
Earlier, an Australian side fielding three debutants - Hughes, Finch and Khawaja - made a bright start in their attempt to stop a three-match losing streak against Sri Lanka at the MCG.
Finch and Hughes added 53 for the first wicket before Ajantha Mendis removed the former, caught behind for 16.
Khawaja did not last long, run out for three by Jeevan Mendis when his bat was over the line but not grounded.
Bailey made a positive start to his innings, timing the ball well, and he and Hughes quickly got to work.
They added 140 runs at exactly run-a-ball rate for the third wicket with Hughes typically strong square of the wicket, hitting five fours in his favourite area.
The left-hander slowed up as he approached his century but regular boundaries from Bailey kept the pressure off before Hughes reached the milestone with a quick single off the bowling of Ajantha Mendis.
Hughes added a further 12 runs before he was caught behind off the bowling of Malinga, and Bailey also fell towards the end, just short of a deserved century when he picked out Jeevan Mendis on the mid-wicket fence off the bowling of Mathews.
Maxwell came and went quickly before Hussey's late hitting - he smashed five fours and one six - helped Australia push past 300, a total that proved beyond their opponents.
