Australia took a 2-0 lead in the ODI series in the West Indies after winning by 63 runs using the Duckworth/Lewis method in Grenada.
The tourists recovered from the loss of three early wickets to register 213-5 on a difficult wicket, and it proved too much for the hapless hosts who could make only 140-8 in 41 overs after rain intervened midway through the reply.
Jerome Taylor put the hosts in good spirits by removing both Shane Watson and Ricky Ponting in his opening spell while Daren Powell accounted for Shaun Marsh as the Aussies found themselves on 35-3.
But Michael Clarke and Mike Hussey grafted hard for a 100 partnership on a pitch with little pace, the former making 56 in 98 balls before he was out lbw to spinner Sulaiman Benn.
Hussey and Cameron White then took the score along to 175 before Dwayne Bravo claimed Hussey's wicket with the left-hander having reached the boundary only twice, plus a six over midwicket, in a 105-ball innings of 62.
White and James Hopes gave the tourists some late impetus, all-rounder White striking three fours in his 40 not out from 39 deliveries to give the bowlers something to aim at.
Dream start for Ronchi
But they needn't have worried as the hosts collapsed in all-too familiar style, Brett Lee providing wicket-keeper Luke Ronchi with a dream start to his ODI career as the pair teamed up to remove Xavier Marshall with the first ball of the reply.
The hosts found scoring just as tough as Australia had done earlier in the day and their impatience proved their undoing, captain Chris Gayle hitting Mitchell Johnson straight to Ricky Ponting while Aaron Fletcher was bowled by Hopes for 19 - the West Indies limping along at 41-3 off 15 overs.
Dwayne Bravo and Patrick Browne struggled to pierce the in-field as the Windies slipped ever further behind the run-rate, Bravo eventually holing out to Hussey off Shane Watson having made three off 21 balls, while Browne scored one from 18 before foolishly hitting Clarke to White at long-on.
West Indies were 58-6 when rained intervened with 27 overs bowled, and they were so far behind on Duckworth/Lewis when the showers passed that only one result was likely.
While Shivnarine Chanderpaul nudged and pushed his way towards another decent score his team-mates continued to give their wickets away, Keith Pollard hitting his second ball straight to Watson to give Clarke his second wicket.
Darren Sammy made nine before spinner Clarke claimed his third victim with Johnson this time taking the catch, but Powell hit some lusty blows to take the West Indies into three figures before Watson cleaned him up.
Chanderpaul (45 not out) and Benn (23 not out) added 35 in just over six overs but it was all academic as the Aussies maintained their dominance over their rivals.
