Fourth one-day international, Brisbane:
Australia 324-7 (50 ovs) beat West Indies 247-8 (50 ov) by 50 runs
Ponting had never previously scored a century in Brisbane
A superb Ricky Ponting century helped Australia beat West Indies by 50 runs in the fourth one-day international to win the five-match series.
Ponting (106) made his 29th one-day ton as the hosts made 324-7 - the highest ever ODI score at the Gabba.
In reply, West Indies made 274-8 with Kieron Pollard (62) and Dwayne Smith (58no) putting on a 102-run stand.
With Doug Bollinger taking 2-44 and Ryan Harris 2-64, Australia opened up a 3-0 lead with one game remaining.
Ponting's clinical innings contained just six boundaries and two sixes but was characterised by two crucial partnerships.
He enjoyed a 52-run second-wicket stand with fellow Tasmanian Tim Paine (24), followed by a 131-run combination with Cameron White, who made an impressive 63 from 78 balls.
Mike Hussey (23 off 17) and James Hopes (42 off 21) helped the hosts reach their total with some late power-hitting as the West Indies pace attack watched in horror as the scoreboard ticked over 300.
Taking a nasty hit to the back of the head, White was cleared of any serious damage after going for an X-ray at a local Brisbane hospital.
Beginning their run chase, West Indies captain Gayle needed to stand firm and he blasted six boundaries in the first five overs.
Refusing to take up anything less than an attacking stance, the tall left-hander moved his side on to 42-0 after five overs - but that was as testing as things got.
The tourists lost two wickets without score as Travis Dowlin edged Ryan Harris through to wicketkeeper Paine and, in the following over, Gayle was edged Bollinger's cutter behind to fall for 34 from 21 deliveries.
Bowling in front of his home crowd, Hopes' introduction in the 10th over worked as Lendl Simmons departed cheaply to leave the West Indies struggling at 55-3.
They only managed to add 10 runs to their total by the end of the 15th over, with Wavell Hinds and Narsingh Deonarine struggling to keep out Mitchell Johnson and Hopes.
Hinds and Deonarine bunkered down and were able to bring up the 100 but a mix-up in the 21st over saw Hopes throw down the stumps with a direct hit, dismissing Hinds after Deonarine refused a quick single.
Sitting at 118-4 at the halfway mark of the innings, Deonarine looked to be like the only West Indies player able to provide any resistance as spinners Nathan Hauritz and Adam Voges came into the attack.
Playing some positive shots, Deonarine brought up his half-century by shovelling Hauritz over mid-wicket but was out the very next ball when he found Harris at long-off.
Denesh Ramdin was the next to depart, playing a Bollinger delivery on to his stumps before Pollard provided some fight, hitting the first six of the innings in the 35th over when he hoisted Harris' slower ball over mid-wicket.
Voges gave Smith a lifeline when he dropped a sitter at mid-off, while Twenty20 specialist Pollard hit Harris for sixes over mid-on and straight down the ground.
Pollard brought up his first ODI half-century off just 43 balls before the 102-run partnership between he and Smith finally came to an end Pollard picked out Hussey down the ground off the bowling of Johnson.
Smith's fifty came in the same over when he hit Johnson for consecutive sixes down the ground but, with the innings drawing to a close, Darren Sammy was bowled for a duck with Harris' final delivery of the night.
