The 22-year-old became the youngest winner on the PGA Tour in 2014 when he fired a closing one under 71 to win the Zurich Classic in New Orleans by two strokes from American duo Andrew Svoboda and Robert Streb.

Noh, who was bogey-free through three rounds and led into the final day, said he hoped his win might provide some escape and joy for a nation that has been in mourning since a ferry capsized on April 16 leaving 300 people missing or dead.

"Hopefully, they'll be happy," said Noh, who wore black and yellow ribbons on his white golf hat to honour the victims of the disaster. “Hopefully they’ll be happy for the Korean guy and win next week.”

The seventh first-time PGA Tour winner in the past 10 years in the New Orleans event, Noh finished at 19 under and earned his best career cheque of $US1,224,000. Noh made his first three bogeys of the tournament in the final round and briefly fell into a tie for the lead with 2011 PGA Championship winner Keegan Bradley.

"Very challenging today out there, especially playing with Keegan, a major champion, and heavy wind," Noh said.

But Bradley played himself out of the tournament with a bogey on the 5th hole and a triple bogey on the 6th hole, while Noh continued to make pars and added some birdies at the 8th, 10th, 13th and 16th to pull clear of the chasers.

Stuart Appleby was the leading Australian in a tie for 17th at 10 under after a final round 69. Queensland’s Bronson La’Cassie was a further shot back and tied for 21st. For Appleby, it was a solid week of ball-striking as he finished tied 8th for greens in regulation and was also impressive from the tee.
