COOLUM, Australia: Australia's Peter Senior won the rain-delayed Australian PGA Monday, beating Geoff Ogilvy with a par on the second hole of a playoff to become the oldest player to win a major professional tournament in Australia. The 51-year-old Senior, a regular on the Champions Tour, made a 10-foot birdie putt on the 18th hole in regulation for a 1-under 71 to match Ogilvy, the Australian Open winner last week in Sydney, at 12-under 276. Ogilvy finished with a 66. It was Senior's third Australian PGA title and comes 21 years after his first. He won at Riverside Oaks near Sydney in 1989 and in 2003 at Coolum. Both players parred the 18th hole on the first hole of the playoff, and Ogilvy three-putted for a bogey on the second extra hole to give Senior his third Australian PGA title. “What a great way to finish the year,” Senior said. “Geoff hit a pretty indifferent iron shot into 18, and we all know how difficult it is to get down from that area. But I would have rather made my (birdie) putt instead of Geoff three-putting, but that's what happens.” Ogilvy said he was disappointed with the finish but not with his play overall in the past two weeks. Twenty-four players finished the round Monday after heavy rain delayed play Sunday. Australians Nick O'Hern (69), Peter Fowler (71) and Andre Stolz (71) tied for third at 11 under. Stolz bogeyed the 18th after hitting his tee shot into the water. American Bobby Gates, who led by a stroke after the third round, bogeyed two of his final nine holes Monday and finished with a 74, leaving him two strokes out of the playoff Ogilvy resumed play Monday on the 14th hole, and birdied that hole and No. 16. Senior, ahead by one when play resumed, bogeyed his first hole of the day - the 10th - after his tee shot in pouring rain Sunday left him in the trees. Defending champion Robert Allenby finished four strokes back after a 70. Gates, playing the Coolum course for the first time, tried to be diplomatic Sunday when play was called despite a tough officiating decision that had forced him to hit an awkward shot out of a bunker that was nearly flooded by rain. He ended up bogeying the hole. Aree Song wins qualifying In Florida, South Korea's Aree Song won medalist honors Sunday at the LPGA's final qualifying tournament, as 17-year-old runner-up Jessica Korda said she would turn pro. Song, 24, finished the five-round tournament at six-under par 354 to earn full playing privileges on the LPGA tour next season. Korda, the daughter of former Czech tennis star Petr Korda, closed with a 77 for 356. She played the tournament as an amateur, but said after her round she would turn pro. LPGA age restrictions mean Korda will have to seek special permission from Commissioner Mike Whan to join the tour. South Korea's Jimin Jeong finished third with a 71 for 357.
