The two-time Masters victor recorded bogey-free back nine at Riviera to edge out Kevin Na and Tony Finau by two strokes to lift his first PGA Tour title for two years after falling from inside the world top ten to No.117 in the rankings.
Bubba Watson won again on the PGA Tour for the first time in two years, claiming his third Genesis Open title at Riviera Country Club.
It reached a point that he wondered if he would ever win again, and he says he talked with his wife on a dozen occasions about retiring. Hogan's victories include a U.S. Open.
McDowell, who shared the overnight lead with Cantlay, carded a one-under par 70. He fell back with consecutive bogeys from the trees and shot 69.
A holed bunker shot a the par-3 14th gave him a lead he wouldn't relinquish and Watson broke down in tears after holing out on the 18th green.
Kevin Na and Tony Finau ended the week tied second with Scott Stallings and Patrick Cantlay in tied fourth.
Phil Mickelson also was in the hunt. But he went after birdie and watched the ball roll 20 feet down the hill, leading to bogey.
Joost Luiten also produced a very strong back nine on his way to winning the Oman Open, his sixth European Tour title, by two shots from England's Chris Wood.
It's been a pedestrian start to the season for Baddeley whose only top-10 in nine events prior to this week came in Las Vegas last November.
Watson started his round with an eagle on the par-5 first hole, his 128th eagle since 2007, the most of any player on the PGA Tour. Watson already had two green jackets. "My goal was always to get to 10 wins and this got me to my 10th win".
"The trend is going in the right direction, and that's what I'm looking for", Watson said.
"You've got to know that this golf course is going to make you mess up, the grass, the way the ball bounces on it, you're going to have shots you think are ideal and ended up not flawless", he said. "I was top 10 in the world for a few years, and so not being there, you feel like, 'Is this it?"
Pacific Palisades: A series of three-putts came in the way of a strong final round for India's Anirban Lahiri, who slipped to tied 26th on the final day of the Genesis Open golf tournament.
Watson, of course, was under par in the stretch.
OK, so making the shot even more remarkable was that exchange with his caddie Ted Scott.
He added a four-foot birdie at 17 and capped his round with an eight-foot par putt at the last. Johnson made a triple bogey on that hole in the opening round. Watson won the Genesis Open for the third time with a two-shot victory, his final-round 2-under 69 capping a 12-under week. "If you can stay around it, you never know what's going to happen the last three or four holes".
