Jonathan Byrd and John Huh were seven points further back in a share of 3rd position with Rod Pampling recording his best PGA Tour finish in more than six years alone in 5th.
Interestingly it was in this modified stableford format that Pampling won one of his two PGA Tour titles.
It was a great change of fortunes for the US Open winner and three time WGC Championship winner, Ogilvy, who in another time and place would have been playing at Firestone this week.
It is perhaps just as well he didn't as this event may well act as the catalyst for a return to his former glory. The victory now assuring him of a start at next week's PGA Championship.
Earlier in the week however Ogilvy was still undecided about even playing this week's event.
"I wasn't even going to come, actually, after Canada," said Ogilvy after Saturday's third round. "Long trip home from Canada, took 14 hours to get home from Canada, as it does from the East Coast to the West Coast.
"I got home and I'm - I really don't want to go this week. I was looking for every excuse in the world not to play because I wanted to have a week off. But everyone convinced me it was a good idea.
"The best thing I did was take three weeks off after Congressional. I mean, I hit the ball so well at Congressional, it's incredible. I couldn't touch the hole from three feet all week. It was really frustrating.
"I wasn't in the Open. I took three weeks off. I just wanted to come back out here again, which was good. I've been working on not working on it too much, if you know what I mean.
"I think about stuff a bit too much when I start, I camp on the range, on the putting green, I start analysing a little bit too much. And I definitely play better when I don't analyse it. I think most people probably do.
"I took a bit of time off and refreshed and just played a few fun rounds of golf, stayed away from the range and the putting green and just tried to hit good shots again, if that makes sense, without actually getting too technical about it.
"So that's all I really did. I was pretty over it kind of just after the U.S. Open, especially at the U.S. Open, I was pretty over it. Again, I hit the ball really well there. I just didn't get anything out of it.
I felt that the only thing it could have been really was I was a bit stale, just a bit over it. I just needed to take a breath and take a few weeks off and want to come back.
New Zealander Tim Wilkinson was 8th, Greg Chalmers 42nd Oliver Goss 45th, Danny Lee 53rd and Bronson La Cassie 59th.
