David Toms made a final-day comeback to claim his first PGA Tour title in five years as he enjoyed a one-shot victory over Charlie Wi at the Crowne Plaza Invitational at Colonial.
After a nightmare round on Saturday, the American started the day a shot behind Wi but his three-under 67 saw him leapfrog the South Korean who shot a one-under 69.
It was Toms' first tournament victory since the Sony Open in Hawaii in 2006 and his 13th on the tour and followed his play-off defeat by KJ Choi at the Players' Championship last week.
"It took a lot of guts," Toms told CBS. "That's what I got by on. I played a great round of golf.
"I've wanted this tournament for a long time. It's a great course for me."
Toms had appeared in total control of the tournament at the halfway stage, posting consecutive rounds of 62 to give him a seven-shot lead going into the weekend.
But a third-round 74 left him one shot behind Wi going into the final round.
However, he holed out for an eagle at the par-five 11th hole to retake the lead.
He said: "When stuff like that happens, it's like it's meant to be."
Wi had never started the final day on the tour in the lead and was three shots behind with three holes to play.
He then made up two strokes with a birdie at the 16th and a Toms bogey at the 17th but his birdie attempt from 44 feet on the 72nd hole came just a foot short.
He has now been a runner-up four times in his tour career.
"I certainly didn't give it to him," Wi said. "He definitely earned it.
"It's great to finish second on the PGA Tour any time.
"But at the same time, it's bittersweet."
Bo Van Pelt was third, a further four shots behind Wi, after a final-round five-under 65, one shot ahead of Zach Johnson.
Robert Karlsson was the leading European in a two-way tie for fifth while Scotland's Martin Laird finished in a six-way tie for 10th.
