Dustin Johnson closed with a 5-under 66 for a five-shot victory over Rory McIlroy in the PGA's 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.
Johnson struggled early and caught a good break from behind a tree on the fifth hole.
He escaped potential trouble on the hole when he was given free relief behind a tree because the heel of his shoe was on the cart path.
McIlroy asked for similar relief on the next hole and was denied when it was deemed he could not attempt the shot. He wound up hitting into the water and made bogey.
