The Australian pair of Marc Leishman and Cameron Smith defeated South Africa’s Louis Oosthuizen and Charl Schwartzel in a play-off to claim the Zurich Classic of New Orleans.
Although the South African duo entered the alternate-shot final round with a one-shot advantage over their Australian rivals, the two teams spent most of Sunday exchanging narrow leads.
The Australians appeared to have coughed up their chances of winning when Smith sent his tee shot into the water on the par-four 16th.
But after a penalty drop in the rough, Leishman chipped-in from about 23 feet to once again draw level with the South Africans.
Both teams completed 72 holes tied on 268, before the Australians took advantage of a wayward tee shot from Oosthuizen on the first play-off hole to clinch the tournament with a par.
Meanwhile, the English duo of Danny Willett and Tyrrell Hatton carded a three-under 69 on Sunday to finish tied for eighth.
Meanwhile Graeme McDowell and Matt Wallace finished on 12 under par, in a share of 23rd place.
