One-day series, Kuala Lumpur: Australia 279-9 beat West Indies 201 by 78 runs
Clarke launches into an off-drive from Ian Bradshaw's bowling
Shane Watson took 4-42 as West Indies went from a position of dominance to crash to a 78-run defeat to Australia in the Kuala Lumpur day-nighter.
Michael Clarke struck a dashing 81 off just 79 balls to lift the Aussies to 279-9 and Ricky Ponting made 56.
But West Indies were in control when Shiv Chanderpaul (90) took them to 172-1 in the 24th over of their chase.
However, wickets started tumbling, the last five falling in 16 balls. Glenn McGrath took 1-30 in his comeback.
Ponting and Simon Katich put on 95 for the second wicket after Australia had won the toss at the Kinrara Academy Oval in the first match of the DLF Cup, which also features India.
Australia named a number of players who are not first-team regulars, such as batsman Mark Cosgrove, wicket-keeper Brad Haddin, and left-arm seamer Mitchell Johnson.
West Indies were fielding their strongest team available.
Clarke's runs were vital for Australia. He came in at four and stayed until the end of the 47th over, hitting nine boundaries in all before being bowled by the expensive Dwayne Bravo.
Once we got those first few wickets we were on a roll. The wicket was very suited to seam bowling
McGrath, out of cricket since January, is using this tournament - and the ICC Champions Trophy - to get match-fit for the Ashes series starting late November.
He bowled a clutch of wides in his first spell, but was economical throughout.
The other bowlers were hit to all parts by Windies openers Chanderpaul and Chris Gayle (60), who put on 136 in 18 overs.
Finally, Watson had Gayle caught at point before Johnson ended Chanderpaul's innings by having him caught behind with a delivery that found extra bounce.
Without their two openers, West Indies foundered, with only Ramnaresh Sarwan (22) holding up the Aussies.
The last seven batsmen collected a grand total of 13 runs.
Ponting said: "We always felt if you had to bat second in these humid conditions it would be difficult. Once we got those first few wickets we were on a roll. The wicket was very suited to seam bowling.
"Glenn was excellent in his second spell and he'll only get better."
A bewildered Lara tried to explain West Indies' dreadful collapse.
He said: "It is difficult to comprehend but I guess these things happen. We've got to dig deep and put this one behind us."
