With his mesmerizing play and cool putting, Watson finished on a total of 25-under 263 to stay well clear of last year's winner Jordan Spieth, who ended fourth behind Patrick Reed (second) and Ricky Fowler (third).
Watson, one of the few left-handers on the PGA Tour, registered his sixth top five finish in last 10 worldwide starts. He had back-to-back birdies three different times yesterday, at the par-3 second, par-5 third, par-5 sixth par-4 seventh and on the first two holes of the back nine.
Watson, 37, who started the opening day carding a five-under was happy to maintain a consistent run in the PGA-sanctioned tournament hosted by the Tiger Woods Foundation.
"I think every year we are getting better at consistency. I believe consistency's the biggest thing about this game. We've seen Tiger, we see Phil (Mickelson), you see Jim Furyk. I can keep naming names, but guys that have been every year and that's what I am looking at," Watson said after the win.
