Sydney: Australia took the fourth ODI in Sydney by five wickets, chasing a target of 221 with Shane Watson (76) and Michael Clarke (37) playing key innings. Earlier, Kieron Pollard had scored his third ODI century to bail West Indies out of a jam and take them to a respectable total.
Australia: 221 for 5 in 44.5 overs Australia make it 4-0 with a comfortable five-wicket win. Michael Clarke departs with the scored leveled, edging a short ball from Tino Best down the leg side for 37, but Glenn Maxwell hit the winning runs.
Australia: 206 for 4 in 42 overs Adam Voges has been dismissed for 28 but Australia remain on course for 4-0 with just 21 needed to win. Looking to pull Andre Russell, Voges got a top edge to midwicket where Darren Sammy held a good catch running back. Australia end the over by reaching 206, with Matthew Wade pulling a free hit for six first ball.
Australia: 176 for 3 in 37 overs Michael Clarke and Adam Voges have put on 31 steadily as Australia inch closer to victory.
Australia: 145 for 3 in 29 overs Tino Best struck Australia their third blow by dismissing Shane Watson for 76. Watson was unable to cope with a short delivery that reared up, and ended up edging to Devon Thomas. A big wicket for West Indies.
Australia: 117 for 2 in 24 overs Sunil Narine has his second wicket, as Phillip Hughes edges to slip for 23. Hughes had been struggling to pick Narine's assortment of deliveries and ended up miscuing a sweep shot. The ball ballooned off his gloves to Dwayne Bravo and that snaps a stand worth 62 in 13.3 overs.
Australia: 108 for 1 in 21 overs Shane Watson has followed his century in Canberra with a solid fifty in Sydney, controlling Australia's chase. It took him 58 deliveries and has helped the total past 100. Watson got a life later in the over two when Narsingh Deonarine collected a throw at the bowler's end but dislodged the bails with his arm before catching the ball. Phillip Hughes was batting on 20, having also had a scare off the final delivery from Deonarine. Hughes was drawn forward but just managed to get his back foot across in time.
Australia: 78 for 1 in 16 overs Shane Watson and Phillip Hughes appear to have Australia's chase in control. The pair has put on 25 so far.
Australia: 53 for 1 in 10 overs Sunil Narine has struck in his first over, getting Aaron Finch (25) lbw when playing across the line. That snaps an opening stand of 53.
Australia: 52 for 0 in 9 overs Shane Watson and Aaron Finch have started Australia's reply strongly. The team fifty has come up in the ninth over with Aaron Finch collecting back-to-back boundaries off Darren Sammy.
West Indies: 220 all out in 49.4 overs A strong finish from centurion Kieron Pollard has taken West Indies to a total which looked a long way off when they slumped to 98 for 7. Pollard took the first two balls of the final over four boundaries but then Tino Best was run out attempting a late second run. West Indies all out for 220 in 49.4 overs. Excellent innings from Pollard, and his second ODI century against Australia.
West Indies: 211 for 9 in 49 overs Excellent century from Kieron Pollard; has it done enough though? He had been turning down singles with Tino Best at the other end, and jumped from 93 to 99 with a big six over long-on off Clint McKay. The landmark came one ball later with a single to long-on. Pollard reached 100 off 132 deliveries. One over to go with Pollard on strike.
West Indies: 201 for 9 in 47 overs West Indies have crossed 200 but lost their ninth wicket. The over began with Sunil Narine (23) nibbling a catch to Matthew Wade behind the stumps. Narine played a good hand in a fine stand of 64 with Pollard. Tino Best is the last man in.
West Indies: 172 for 8 in 43 overs Kieron Pollard has started to tee off. Two fours in the 42nd over from James Faulkner followed by three off the last four of the 43rd, the last from Ben Cutting, take the allrounder to 74. Cutting's last over goes for 12 and he finished with 3 for 45. Can West Indies reach 200 and more?
West Indies: 137 for 8 in 39 overs Andre Russell's cameo ends on 18. Having pulled Clint McKay for six in the previous over, Russell went for a slog against James Faulkner and found the fielder at long-off. Kieron Pollard, however, has crossed fifty off 95 deliveries.
West Indies: 98 for 7 in 32 overs Ben Cutting's strong day continues. He gets his third wicket, again caught in the slips. Darren Sammy chases a delivery outside off stump and edges to Michael Clarke at first slip for 25. In walks Andre Russell.
West Indies: 88 for 6 in 30 overs Kieron Pollard and Darren Sammy have taken their stand to 33 as West Indies attempt to make something of a messy situation. Pollard was batting on 31 off 71 balls - the first time in the series he reached double figures - while Sammy was on 17 off 31.
West Indies: 55 for 6 in 20 overs Ben Cutting has taken his second wicket in as many overs, though not without a bit of drama. The sixth wicket to fall is Devon Thomas, caught at slip by Aaron Finch though the dismissal was not so straightforward as the last Cutting-Finch combination. Thomas nicked the ball to second slip where Finch claims it, but the umpires are not sure of the legality. It is referred and after several replays confirmation comes that Finch did scoop it up cleanly.
West Indies: 46 for 5 in 18 overs The out-of-form pair of Kieron Pollard and Devon Thomas found themselves needing to stage a remarkable recovery after West Indies lost their fifth wicket in the 18th over. The last man to go was Narsingh Deoarine, caught at slip by Aaron Finch off Ben Cutting.
West Indies: 22 for 4 in 10.4 overs Michael Clarke introduced spin rather early by throwing the ball to Glenn Maxwell and the allrounder didn't disappoint. Maxwell trapped Dwayne Bravo infront of the stumps, but the umpire didn't raise the finger. Immediately, Australia went for the DRS and got the decision in their favour.
West Indies: 17 for 3 in 7.6 overs On the last ball of the over, Johnson digged in a short one that hit Darren Bravo's (4) handle and carried to Aaron Finch for a simple catch.
West Indies: 17 for 2 in 7.3 overs Johnson struck again when Kieran Powell (9) looked to play a short ball through the on-side but got a got a leading edge to the point fieleder.
West Indies: 5 for 1 in 3.5 overs Mitchell Johnson got the ball to swing back which was enough to go through opener Johnson Charles (0) defense.
Earlier, the West Indies skipper Darren Sammy won the toss and elected to bat against Australia in the fourth one-dayer on Friday.
The man in form for Australia, George Bailley misses out due to a hamstring injury and is replaced by Adam Voges, while Ben Cutting comes in place of Mitchell Starc. On the other hand, the West Indies have made three changes - Johnson Charles, Deonarine and El Tino come in for Chris Gayle, Ramnaresh Sarwan and Kemar Roach.
Australia have taken an unassailable 3-0 lead in the five-match ODI series.
