Queensland, Australia (SportsNetwork.com) - Greg Chalmers parred the seventh playoff hole on Sunday to defeat Adam Scott and Wade Ormsby and win the Australian PGA Championship.

Chalmers fired the low round of the week, an 8-under 64, to finish at 11- under-par 277. Scott and Ormsby, who shared the third-round lead with Scott Strange, both closed with 1-under 71s to force the extra session.

The trio played the 18th at RACV Royal Pines Resort Gold Coast until a winner was determined. All three parred the first two extra holes with Ormsby missing a chance at winning the title on the second playoff hole.

Chalmers and Scott birdied the third extra hole and that knocked Ormsby out of the playoff as he had missed the putting surface and was looking at a par putt after chipping on to the green.

After Chalmers scrambled for par from the trees, Scott missed a birdie chance from just outside 12 feet for the win. He tapped in for par and they headed back to the 18th tee once again.

Scott had a similar putt for birdie the next time through and missed again as they both made par. They both 2-putted for par the sixth time they played the 18th.

The 34-year-old Scott finally cracked the seventh time around. Chalmers rolled a long birdie chance to three feet. Scott's birdie try missed and trickled four feet past the cup. He missed the short par putt, but Chalmers did not.

Chalmers rolled in his 3-footer for par and the win. This was his second Australian Open Championship title and his fifth victory overall on the PGA Tour Australasia.

Michael Hendry closed with a 1-under 71 and he finished alone in fourth at minus-9. Scott Stallings carded a 2-under 70 to take fifth at 8-under 280. Boo Weekley tripped to a 2-over 74 to slip into sixth place at minus-7.

Strange faltered to a 4-over 76 and he dropped to 6-under-par 282. Matthew Giles shot 2-under 70 to join Strange in a share of seventh place.
