RENO, August 4, 2014 (AFP) - Ogilvy earned 14 points Sunday under the Modified Stableford points scoring system used in the event, giving him 49 total points, five more than runner-up Justin Hicks of the United States.
Americans John Huh and Jonathan Byrd shared third on 37, each making 11 points in the final round, with Aussie Rod Pampling fifth after an 11-point last day.
It was Ogilvy's eighth career victory on the US tour, his first since 2010 at Kapalua, Hawaii.
Ogilvy, the 2006 US Open champion, also became the first player from beyond the US borders to win the event in its 16-year history.
Point awards in the unique event were eight for a double eagle, five for an eagle, two for birdies, none for pars, minus-one for bogey and minus-three for double bogey or worse.
Ogilvy made birdies at the fourth and fifth holes and sank a 33-foot birdie at the par-3 seventh.
After surrendering a point with a bogey at the 12th by missing an 11-foot par putt, Ogilvy answered by sinking a 27-foot eagle putt at the par-5 13th, then making birdie at 14 and the par-5 18th as well.
