Kevin Streelman finally won on the PGA Tour. He didn't make a bogey over the final 37 holes on the tough Copperhead course at Innisbrook. He closed with a 4-under 67 on Sunday for a two-shot win in the Tampa Bay Championship at Palm Harbor, Fla.

Boo Weekley, who teed off three hours before the leaders, had a tournament-best 63 and waited to see if that would be enough.

Streelman hit 5-iron into 6 feet on the par-3 13th, the toughest hole at Innisbrook, to take the lead for good.

"Probably the best shot of my life in that situation," he said. "It's just how I envisioned it, and I pulled it off."

He locked up the win with a 20-foot birdie putt on the par-3 17th and was all smiles walking up the 18th fairway.

Streelman, 34, won in his 153rd tour start, and it sends him to the Masters next month for the second time.

"I had a peace about me today," said Streelman, who won $990,000 after finishing at 10-under 274.

Cameron Tringale (66) was third at 277. Justin Leonard (71) three-putted 18 for bogey, sharing fourth with Luke Donald (69) and Greg Chalmers (70) at 278.

LPGA Tour: Stacy Lewis won the Founders Cup to jump to No. 1 in the world, taking advantage of Ai Miyazato's collapse on the 16th hole.

A day after Lewis was penalized two shots for caddie Travis Wilson's blunder on the short par-4, the American took a two-stroke lead with a birdie on 16 after Miyazato made double bogey. Miyazato's approach shot left her with an unplayable lie in a desert bush. Lewis ended Yani Tseng's 109-week run at No. 1. Lewis, who won $225,000, shot a 8-under 64 at Phoenix's Desert Ridge to finish at 23-under 265. Miyazato (71) was second at 268.

Champions Tour: David Frost won the Toshiba Classic at Newport Beach, shooting a 6-under 65 to beat Fred Couples (69) by five strokes. Frost, who tied the tournament record of 19-under 194 set by Jay Haas in 2007, won $262,500. Haas (67) and Peter Senior (66) shared third at 202.
