Camilo Villegas, Henrik Norlander and Blayne Barber all bogeyed the hole and Billy Horcshel had bogeyed the first extra hole on Sunday to be eliminated from the contest although he of course shares second position with the other four.
Hughes had led the event from wire to wire after his brilliant opening round of 61 on Thursday and led by one over Horschel and Villegas heading into Sunday.
Hughes who turns 27 on Wednesday earned the best possible birthday present as he now has PGA Tour exemption through until the end of 2019 and a start at the Masters in April.
Hughes gained his PGA Tour status via the Web.Com Tour, where he won one of the events late in the season, and had already made a good start with an encouraging 13th place finish on debut at the Safeway Open.
This win however changes his career and life given the trappings that go with it.
Cameron Percy did best of the Australians when he finished 21st earning US$60,000 for his effort while Brett Drewitt was the only other to make the cut and finished 67th.
