Unheralded American Chris Couch produced one of the PGA Tour's most unlikely wins with a dramatic one-shot victory at the Zurich Classic of New Orleans.
The 32-year-old from Florida, who has played mainly on the minor Nationwide Tour, chipped in from 50 feet at the last for an unlikely par-four and a seven-under-par 65.
That left Couch on 19-under 269, just ahead of playing partner Charles Howell III whose 65 earned him a tie for second with PGA Tour veteran Fred Funk, after a best-of-the-week 62.
"This means so much," a beaming Couch told reporters after receiving a winner's cheque for $1.08 million, more than triple his previous career earnings on the PGA Tour.
"It hasn't sunk in yet, but for a guy who has come from nothing to now have a million dollars is absolutely incredible. I would have liked to have made it a little easier, I will tell that you," added Couch, a five-times winner on the Nationwide Tour. "My heart can't take many of those.
"It couldn't have been a better finish. I'm sure the crowd loved it."
One stroke clear overnight, Couch covered the front nine at English Turn Golf & Country Club in a blistering six-under 30 to forge three ahead of the chasing pack.
Hardly surprisingly, the final round featured plenty of low-scoring on receptive greens softened by an overnight thunderstorm.
Despite feeling the pressure down the stretch, the twice All-America selection from the University of Florida appeared to have the title firmly within his grasp after a three-foot birdie putt at the 16th put him two ahead.
However, the tobacco-chewing American dropped his only shot of the day after finding damp sand in a greenside bunker off the tee at the par-three 17th and did well to avoid a double-bogey there by holing a 10-footer.
Against the odds, he avoided another error on 18, despite finding a poor lie in the back of another bunker after overhitting the green with his wedge approach and underhitting his third shot into a collar of rough.
"I had two chip-ins today, which is unbelievable for me," said Couch, who uses an unconventional cross-handed grip for chipping. "I don't remember the last time I did that.
"When I was over that last shot. I was thinking this would be a great way to win the golf tournament, chip this thing in here. It would be something to remember always."
It a good final day for the Irish duo of Padraig Harrington and Graeme McDowell, who finished tied 11th and 15th respectively. Harrington shot 66 while McDowell carded a 66.
Australia's Stuart Appleby, hunting his third PGA Tour title this year, holed his approach at the sixth for an eagle-three on his way to a 64 and a share of fourth at 15 under with Americans Brett Wetterich (66) and Joe Durant (68).
American Lucas Gover was a further stroke back in a four-way tie for seventh, a run of six birdies in seven holes helping him to a 63.
Masters champion Phil Mickelson, chasing his third title in a row, had to settle for a share of 15th after closing with a 69.
"I was hoping to get that first place, but I think the two-week layoff got to me," said Mickelson, who has not played since his Masters triumph earlier this month. "I never really had a feel for the greens here."
