Sydney: Opener Shane Watson scored 76 to back up his century on return from injury two days ago to lead Australia to a five-wicket win over West Indies in the fourth one-day cricket international at the Sydney Cricket Ground on Friday.
Australia scored 221-5 in 44.5 overs to spoil Kieron Pollard's unbeaten 109 in West Indies' 220 all out in 49.4 overs.
The win was Australia's fourth in a row in the five-match series. The final game is on Sunday at the Melbourne Cricket Ground.
Pollard, who hit a towering six to get to 99, notched his century with a single on his next ball in the second-to-last over to complete his second one-day hundred against Australia.
Australia clinched the series with a 39-run win on Wednesday in Canberra.
Australia pace bowler Mitchell Johnson (3-36) had the visitors in trouble at 17-3 after eight overs. Ben Cutting (3-45) also secured his first three-wicket haul in ODIs after being called into the team for the rested Mitchell Starc.
Adam Voges (28) replaced George Bailey, who was ruled out of the home side with a slight hamstring strain. Captain Michael Clarke made 37 before falling with one run required for victory.
Cricket Australia announced later that wicketkeeper Brad Haddin would join the squad for Sunday's match in place of Matthew Wade, who is departing on Saturday for India for the upcoming four-test series on the subcontinent.
