Off the back of a history-making half-century from Chris Gayle, the West Indies claimed the third T20I against Australia to wrap up the series in Gross Islet on Monday.
Sent out to bowl first, West Indies held Australia to a total of 141 for six from their 20 overs and chased that target down with six wickets and 31 balls to spare.
Gayle blasted seven sixes and four fours as he raced to 67 off 38 balls to power the hosts to victory, becoming the first batter to score 14,000 T20 runs as he notched his 14th T20I half-century for the West Indies.
He was particularly brutal against Adam Zampa, going past the 14,000-run milestone with a six off the spinner in the ninth over.
Earlier, Australia enjoyed their most positive start of the series with the bat with Aaron Finch and Matthew Wade putting on a 41-run stand before Obed McCoy (1/9) bowled the latter for 23.
The Australian innings failed to get going from there as the in-form Mitchell Marsh was trapped in front by Fabian Allen before Alex Carey and Finch fell to Hayden Walsh Jr in the 12th over to leave the tourists at 80 for four.
Australia: 141/7 in 20 overs (Henriques 33 n.o, Walsh 2/18)
West Indies: 142/4 in 14.5 overs (Gayle 67, Pooran 32 n.o, Meredith 3/48).
