Fred Funk overcame back pain and a rocky final round to win the Mayakoba Golf Classic in Playa del Carmen, Mexico, on the second hole of a playoff with Jose Coceres, making him only the second man to win on the regular tour after winning on the Champions Tour.

"It shows that the old guy has still got something," Funk, 50, said. "It's a very satisfying win.

"I think I validated how good the players are on the Champions Tour. Even though you are 50 or 51 through 55 . . . age doesn't really mean anything. I just want to see how long I can last."

Funk led the tournament, the PGA Tour's first in Mexico, from the start, setting the course record with an 8-under 62 on Thursday. He never lost the lead, but was tied several times, including from the 14th hole until sinking a birdie putt in the playoff.

The former University of Maryland coach closed with a 1-over 71, matching Coceres (69) at 14-under 266 on the Greg Norman-designed El Camaleon course.

The eighth PGA Tour victory of his career was worth $630,000. Tied for 13th place was Kevin Stadler, whose father, Craig, was the first Champions Tour winner to claim a PGA Tour title, doing so back in 2003 when he won the Senior Players and B.C. Open in consecutive weeks.

Stadler had been the fifth-oldest PGA Tour winner, but at 50 years 8 months 12 days old, Funk claimed that honor.

Australian Peter Lonard, who played with Funk and Coceres, birdied the final hole for a 67 to finish third at 13 under. Ryan Armour (66) was 12 under, and Bill Hass (67) followed at 11 under.

Funk came into the final round with a two-shot lead and a back problem that bothered him so much Saturday he wondered whether he'd be able to finish.

On the second playoff hole, the par-3 10th, Funk put a 4-iron within six feet. Unlike Coceres, Funk knocked his potential winning putt with so much confidence that he threw a victory punch before the ball even fell.

The victory was Funk's first on the PGA Tour since The Players Championship in 2005. It wasn't his first title in Mexico, though -- he won the 1992 Mexico Open.

· CHAMPIONS TOUR:Bobby Wadkins won the ACE Group Classic, holing a 13-foot birdie putt on the final hole for a 4-under 68 and a one-stroke victory over Allen Doyle in Naples, Fla.

Wadkins, the brother of 2000 champion Lanny Wadkins, finished with a 15-under 201 total and earned $240,000 for his fourth Champions Tour title. Doyle, the 1999 champion, shot a 70.
