Jason Bohn held off all challenges to complete a wire-to-wire win in the Zurich Classic of New Orleans at TPC Louisiana on Sunday.
Bohn clinched the second PGA Tour title of his career a day after celebrating his 37thbirthday with a final-round, five-under-par 67, to get to 18 under and win by two shots from fellow American Jeff Overton with rookie Troy Merritt third on 14 under par and two-time US Open champion Lee Janzen fourth a further shot back.
Bohn had led since an opening 65 and stretched his lead after the rain and lightning-delayed second round from two to four before it was chipped away heading into the final round.
Bohn, who had completed his third round on Sunday morning at 13 under, led by two shots over Germany's Alex Cejka after 54 holes with Overton and Janzen at 10 under.
He started slowly in search of his first win since the 2005 BC Open, not getting his first birdie until the eighth hole as Merritt made his move, going out in a three-under-par 33 and then sinking birdies at the 10th, 11thand 13th.
With five holes to play, Merritt was a one-shot leader over Bohn at 15 under but they swapped places at their next holes as the 24-year-old rookie bogeyed the 14thand Bohn birdied the 11thto retake the lead at 15 under.
Janzen made a push for a first title since the 1998 US Open when he eagled the par-four 13thbut a bogey at the par-four 16thended his bid.
Then Bohn moved up a gear, dialling in his approach shot at the par-four 15thfrom 217 yards to set up a short putt for birdie and adding another at 16 to move two strokes ahead of Overton, who had birdied the 13thto get to 15 under.
As they played the last, Overton kept it interesting by giving himself an long eagle putt with his approach to the par-five 18thbut he was trumped by Bohn who with his shorter approach pitched to inches from the hole for a guaranteed birdie and victory.
Overton closed with a birdie to get to 16 under with a six-under 66 and second place with Merritt taking a 67 for third place and Janzen a 69 for fourth.
Australian Greg Chalmers was fifth at 12 under following a 69 while compatriot Stuart Appleby sealed his second consecutive top-10 in sole possession of sixth place on 11 under.
England's Greg Owen and Sweden's Daniel Chopra were the leading Europeans as part of a tie for 16thplace, after a closing 72 and 70 respectively with another Swede, Mathias Gronberg, finishing birdie, birdie but still shooting a 74 to close at seven under.
Cejka fell further than Gronberg to get to the same place, a tie for 21st, with a two-birdie, six-bogey 76 that saw him slip from contention.
England's Justin Rose had a three birdie, one bogey 70 to finish on four under and Brian Davis closed with a 76 on two under for the week, seven days on from his runner-up finish at the Verizon Heritage, when he called a penalty on himself during a sudden-death play-off with Jim Furyk.
