A PGA Tour rookie is now a YouTube sensation.
James Hahn, a Korean-American pro, has become a hit on the video website after his "Gangnam-style" celebration dance after a birdie in the final round of the latest event at Phoenix.
Hahn mimicked the now famous dance by Korea's Psy in front of the party hole crowd where rowdy spectators are encouraged to make noise.
He says he was having so much fun that he just did it without even thinking.
