Greg Chalmers prevailed Sunday in a playoff at the Australian PGA Championship after playing seven holes of sudden death against Adam Scott.

Chalmers, who shot an 8-under 64 Sunday at Royal Pines on the Gold Coast of Australia after trailing the leaders by seven strokes going into the final round, and Scott and Wade Ormsby, who both shot 71, finished 72 holes at 11-under 277.

Chalmers, an Australian who plays left-handed, finished his round about an hour before the other two players in the playoff. He won the Australian PGA Championship in 2011, also following a three-way playoff.

Scott missed birdie putts inside 15 feet on the first two playoff holes that would have won the title. Ormsby, however, was the first to drop out of the playoff when he parred the third playoff hole – Scott and Chalmers birdied.

Finally, Scott missed a 4-footer for par on the seventh hole, allowing Chalmers to take the title with a tap-in.

“Just phenomenal, I’m worn out,” the 41-year-old Chalmers said. “I was all over the place … really excited and thrilled.”

The playoff was the longest for a top-tier tournament in Australia. Chalmers’ putting was the difference in the marathon finish.

As for Scott, the Australian PGA Championship marked a third event in Australia in the past four weeks. Scott has struggled to come out of the gate with authority, but seemed to move past that at Royal Pines when he opened with 68.

Last year, Scott won the Australian PGA and Australian Masters and lost the Australian Open – the third leg of the Australian Triple Crown and the final Australian major of the season – when Rory McIlroy birdied the 18th hole on the final day at Royal Sydney.

This year, Scott failed to defend his PGA and Masters titles. He played two weeks ago in Sydney when American Jordan Spieth shot a final-round 63 to win by eight strokes at the Australian Open. Scott was nine strokes behind and was tied for fifth.

Scott, who announced Friday that he and his wife are expecting their first child in February, said Sunday that his short irons weren’t good enough.

“I didn’t hit it close enough today to the hole,” Scott said. “It wasn’t like I missed 10 footers today all day long. When you hit it outside 25 feet, there is almost the same chance you are going to three-putt as two-putt on tour. You have to hit it closer.”
