The Australians showed no signs of relaxing even though they lead the West Indies comfortably in the 5 match one day series.
Mitchell Johnson shocked the Windies top order by blowing away Charles, Powell and Bravo.
Kieron Pollard played an uncharacteristic knock to bring some respectability to the total, with some late order assistance from Skipper Sammy and Narine.
However, when they bowled, except for Narine who was tight and efficient and Tino Best who consistently troubled the batsmen with his fiery pace, the Windies bowlers were not good enough on the day.
