MARANA, Ariz. — Even as Hunter Mahan motored his way through the Match Play Championship by beating one tough opponent after another, he had reason to feel he was just along for the ride in the final match Sunday afternoon.

All the chatter was about U.S. Open champion Rory McIlroy and his march to No. 1 in the world.

All the chants Mahan heard as he walked down the first two holes at Dove Mountain were for McIlroy.

With a little extra motivation he didn’t need, Mahan won three straight holes on the front nine to seize control and answered McIlroy’s charge with birdies of his own for a 2-and-1 victory.

“Deep down, you wanted to postpone that crowning of the No. 1 player in the world for Rory,” Mahan said. “He’ll get there. I mean, he’s phenomenal. He’s really talented. He’ll be No. 1 eventually. But yeah, when you’re a player, and I listen to Johnny Miller and Nick Faldo and all those guys, they had him picked to win. And that’s what everybody was talking about.

“There was absolute motivation in that.”

It proved to be too long of a day for McIlroy, the 22-year-old from Northern Ireland, who put so much energy into a high-stakes semifinal match against Lee Westwood earlier Sunday. If either of them won the tournament, they would go to No. 1 in the world.
