Rising American talent Jordan Spieth shot the round of his life for an eight-under-par 63 as his rivals labored in the Sydney wind to claim his second professional title by six strokes at the Australian Open on Sunday.
The Texan, who shared second place on his U.S. Masters debut in April, fired eight birdies in a flawless final round to secure the Stonehaven Cup at 13-under 271 for the tournament at The Australian Golf Club.
The $1.06 million tournament had been billed as a duel between world No. 1 Rory McIlroy and No. 3 Adam Scott but 21-year-old Spieth stole the show with his stunning final round.
"I didn't think the round was out there but the putts just kept going in," Spieth said in the greenside presentation. "It's the best round I've ever played, the best win I've ever had, it's pretty awesome."
