MEXICO CITY — Dustin Johnson struggled early, caught a good break from behind a tree and then breezed to his sixth World Golf Championship title on Sunday by closing with a 5-under 66 for a five-shot victory over Rory McIlroy in the Mexico Championship.
Johnson started the final round with a four-shot lead. But with that lead cut in half after three holes, Johnson escaped potential trouble on the fifth 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.
Johnson birdied and was on his way. McIlroy closed with a 67.
