Graeme McDowell's barren run came to an end as the Northern Irishman beat Russell Knox and Jason Bohn in a play-off to win the OHL Classic at Mayakoba.
McDowell and Knox held the lead at 19 under when 27 players returned to the course on Monday to complete the final round of a tournament interrupted by rain.
In windy conditions, Scotland's Knox looked set to follow up his maiden victory at last week's WGC-HSBC Champions with another success when he headed to the final hole holding a one-shot advantage.
However, a bogey at the last for Knox resulted in a three-way play-off and McDowell, whose last top-10 finish came at the European Tour's Dubai Desert Classic in February, duly prevailed courtesy of a stunning approach shot that set up a birdie at 18.
Discussing his second shot in the play-off, which left a putt of around three feet, McDowell said: "I hit as good a five-iron as I could hit. I was thinking six-iron to be honest and he [my caddie] said five-iron."
Bohn, two shots off the pace overnight, and Knox each found birdies on 13 when play resumed at 8am local time in Playa del Carmen.
Knox bogeyed 14 and then missed a golden chance to regain the shot when a stunning tee shot at 15 was followed by a missed putt from close range.
Last week's winner in Shanghai nevertheless found himself one clear of Bohn and McDowell as the latter made five at the par-four 16th.
Yet Knox was unable to finish with a par and McDowell then took centre-stage to secure his first PGA Tour win since he triumphed in a play-off at the 2013 RBC Heritage.
