Opener Shane Watson top-scored with 76 as Australia drubbed West Indies by five wickets in the fourth ODI at the Sydney Cricket Ground on Friday.
Kieron Pollard earlier hit a defiant unbeaten century to haul West Indies almost single-handedly to 220 all out but it never looked like being enough and the hosts took a 4-0 lead in the five-match series with 31 balls to spare.
Watson scored a century on his return from injury as Australia wrapped up the series on Wednesday but his innings was not as assured on Friday and he had a couple of lives before departing, caught behind.
Left-arm paceman Mitchell Johnson (3/36) ripped through the West Indies' top order and for a while it looked like Australia might crush the visitors. The big-hitting Pollard, though, fought a one-man rearguard action with a brilliant 109 not out.
