Veteran Ken Duke claimed his first PGA Tour title at the 187th time of asking with victory at the second extra hole at the Travelers Championship in Connecticut.
After three second place finishes, the 44-year-old finally came good after Bubba Watson lost his lead on the back nine for the second successive day.
The former Masters champion, who was three clear at one stage on Saturday, held a one stroke advantage after picking up his fifth birdie of the day at the 15th, only to rack up a triple-bogey at the next hole.
That left Duke, who himself had birdied the 15th, in sole possession of the lead at -12 and he parred the final three holes only to see closest pursuer Chris Stroud chip-in from off the green for birdie at 18 to force the play-off.
Stroud, also seeking a maiden win, holed out from six feet to keep his hopes alive but could do little after watching Duke stick his approach to just two feet as they came back down the 18th a second time.
The win clearly meant a great deal to Duke, who has overcome a debilitating back problem to carve out a living on the tour.
He and Stroud finished one shot clear of Graham DeLaet in regulation play, the Canadian's hopes evaporating with a bogey at the 16th, while Watson finished two back after appearing to take charge with four birdies in seven holes before disaster struck.
Webb Simpson book-ended the tournament with another 65 to secure a tie for fifth place with JJ Henry, while Charley Hoffman was a further shot back following a 72 after starting the day in a share of the lead.
New US Open champion Justin Rose had a brief flirtation with the top of the leaderboard, getting within a shot before falling back with three bogeys in his last 10 holes, nevertheless supplementing last week's gains with a solid outing.
However, there was a disappointing end for Lee Westwood who brought up the rear with a 78 that included three double bogeys and a four-putt, although Padraig Harrington was even worse with a birdie-free 80.
