MEXICO CITY (AP) Dustin Johnson struggled early, caught a good break from behind a tree and then breezed to his sixth World Golf Championship title Sunday by closing with a 5-under 66 for a five-shot victory over Rory McIlroy in the Mexico Championship.
Johnson won for the 20th time on the PGA Tour, making him a lifetime member when he puts in 15 years on tour. In his 12th season, he is the 38th player in tour history to reach 20 wins.
McIlroy was five behind at the turn and ran off six birdies in a seven-hole stretch before closing with a meaningless bogey for a 67. Johnson was right there with him with five birdies on the back nine.
