"It's been too long. It's been a hell of a two years since I sat here as a winner," McDowell said. "We all put winning up on a pedestal as the ultimate goal. We like to say that it's all about the process and going through the motions and trying to get better. But let's be honest. We all measure ourselves by the win. I can say that now."
The three-shot margin made it look easier than it was.
Sherwood was playing longer than ever in a light rain, giving an advantage to a big hitter like Bradley, not to mention tournament host Tiger Woods. Even when McDowell built a four-shot lead through 11 holes, a careless three-putt bogey on the 13th brought Bradley within two shots with five holes to play.
McDowell responded with a 75-foot putt that he lagged to tap-in range, a key moment for someone coming off a three-putt bogey. From a precarious spot behind the 17th green, he had to land his chip in the rough and hope it would hop onto the fringe and not run too far by the hole. He pulled it off perfectly.
"It was an inch away from sticking in the fringe, and about 1-16th of an inch away from going in the hole," he said.
He made one last birdie he didn't need, extending his dominance at Sherwood. It was the 10th time in 12 rounds at Sherwood that McDowell has shot in the 60s, and he now has two wins and a runner-up finish in his three trips to the World Challenge.
"This really caps off my season," McDowell said. "We try not to put winning on a pedestal, but this one feels very sweet because it's been a grind all year."
McDowell won for the first time since he beat Woods in a playoff at Sherwood in 2010.
