Naples - Kenny Perry and Sean O'Hair birdied five of the last six holes in the final-round scramble on Sunday to win the Franklin Templeton post-season golf event by one stroke.
The duo combined for a 12-under 60 to finish at 31-under-par 185.
O'Hair won this event for the first time, while Perry won for the third time with his third different partner and at 52 became the oldest winner in the event.
He won with John Huston in 2005 and Scott Hoch in 2008.
"All three have been different," Perry said of his Shootout victories. "John and I were pretty even partners, and then the year Scott and I won, I played fantastic that week. ... This year, my roles have been reversed, and I was complementing Sean."
O'Hair added: "I think that was kind of the best thing about this was just we had a ton of fun, just like being a kid enjoying what you're doing."
Hosted by Aussie great Greg Norman, the tournament features 24 golfers playing in two-man teams in a mixed-format of modified alternate shot, better ball, and scramble.
Perry and O'Hair, who led by two strokes going into the final round, will share $750 000 of the $3 million total purse.
South Africa's Rory Sabbatini and American Charles Howell threatened with a back-nine surge that included an eagle on a par-four, but even combining for a final-round 57 they came up short on 186.
"We played really well and gave ourselves a lot of opportunities," Sabbatini said. "We put a good number up there and that's all we can really do. We had a lot of fun and Charles hit the ball fantastically."
Jason Dufner and Fiji's Vijay Singh finished third at 28-under.
