Set a challenging target of 271 after wicketkeeper Matthew Wade's unbeaten 57 led an Australian lower-order revival from 173 for six to a final total of 270 for nine off 50 overs, Marsh claimed the prized wickets of Darren Bravo and Marlon Samuels, adding the scalp of opening batsman Johnson Charles for good measure to effectively short-circuit the home side's pursuit.

His disciplined medium-pacers realised miserly figures of three for 32 with the West Indies unable to recapture the impressive batting form of earlier matches in being dismissed for 212 off 45.4 overs at Kensington Oval in Barbados on Sunday.

Josh Hazlewood polished off the tail to finish with the best figures of five for 50, but it was Marsh's spell that made the difference when it mattered most.

"We really fought well tonight and I always felt we could defend that total," said victorious captain Steve Smith. "It's just the way we play. We believe in ourselves and go hard at the opposition every time."

Charles topscored with 45 and featured in an encouraging opening partnership of 49 with Andre Fletcher.

They weathered the early assault from Mitchell Starc but it was fellow new ball bowler Hazlewood who prised out Fletcher in the 11th over of the innings.

Marsh, adjudged Man of the Match, then cemented Australia's control of the match when he had Bravo caught behind, Samuels taken at short extra-cover and Charles leg-before within the space of ten runs.

At 72 for four and with the top batsmen gone, West Indies' chances of victory had lurched into improbability, especially when leg-spinner Adam Zampa lured the big-hitting Kieron Pollard into hoisting a catch to long-off.
