(REUTERS) - World No. 5 Jordan Spieth drained a 12-foot birdie putt to win the Australian Open for the second time after a three-way sudden death play-off at Royal Sydney on Sunday (Nov 20).

The American, winner of the Stonehaven Cup in 2014, finished on 12-under for the tournament after a three-under 69 to join Australian clubhouse leaders Ashley Hall and Cameron Smith, who both shot final-round 66s.

Replaying the par-four 18th hole, Hall landed his approach shot closest but was unable to nail his birdie putt, while a 35-foot putt also proved too long for Smith.

Spieth will be hoping his second Australian Open title will prove as much of a springboard as his first. The 23-year-old followed up his 2014 triumph by winning five titles, including the US Masters and US Open last year.
