MEXICO CITY — Patrick Reed was more concerned about how to save par than how to answer his critics. He was consumed with navigating around the trees from 152 yards away with a gap wedge more than any chatter about his character.

Reed only plays for himself. And when it feels as though the world is against him, he plays his best.

A week that began with Brooks Koepka saying he thought Reed cheated when he was penalized for swiping away sand in the Bahamas ended with Reed delivering clutch moments down the stretch Sunday to win the Mexico Championship.

Two shots behind with four holes to play, Reed ran off three straight birdies to overtake a faltering Bryson DeChambeau, closing with a 4-under 67 for his second World Golf Championships title.

As for the outside noise?

“I’m used to it,” Reed said. “Honestly, it’s one of those things that at the end of the day, all I can control is me and what I do on and off the golf course.”

If questions remain, they have nothing do with his moxie.

Reed made it interesting in the end with a wild tee shot into the trees on the 18th hole, forcing him to chip back to the fairway. He had to two-putt from 35 feet for eighth victory of his PGA Tour career.

He one-putted 45 times over 72 holes, an astounding performance on the poa greens of Chapultepec.
