Noh Seung-yul claimed his first PGA Tour win on Sunday as he held off the chasing pack to secure a two-shot victory at the Zurich Classic of New Orleans.

The South Korean came into his final round with a two-shot lead and also looking to become the first player to record a bogey-free 72 holes since Charles Howell III at the Greenbrier Classic in 2010.

That dream was extinguished with a bogey on the first but a final round of 71 was good enough to leave Noh 19 under, two shots clear of Andrew Svoboda and Robert Streb.

After the dropped shot on the first, the 22-year-old regained his composure and reeled off six pars before picking a shot back up on the eighth to turn in 36.

Another birdie at the 10th was to follow and Noh would also pick up shots back up on 13 and 16 after bogeying 12 and 15.

A poor tee-shot on the par-three 17th suggested nerves were kicking in as the finish-line approached, but an excellent up and down secured a par and Noh made no mistake on 18.

Svoboda recorded a closing 69 with birdies on five, seven, 12 and 18 and a bogey on six, while Streb recorded just six pars in a chaotic 70.

The American eagled the second before bogeys on the third and sixth were followed by birdies on the seventh and eighth. A double-bogey on nine and a bogey on 10 had Streb over par for the day but he picked up shots on 12,13 and 16 before a bogey on 17 and a closing birdie.

Jeff Overton was a further shot back after also shooting a 70, two shots clear of Erik Compton, Charley Hoffman and Robert Garrigus, who signed for a round-of-the-day 64.

US Open champion Justin Rose closed with a 68 to finish 13 under in a group with Keegan Bradley, who endured a desperately disappointing 75.

The former US PGA champion was level for his round after five holes but a triple-bogey on the sixth effectively ruined his chances of victory.

Englishman Paul Casey fired a 73 to finish 12 under, while Padraig Harrington finished one under for the tournament.
