MARANA, ARIZONA HUNTER Mahan beat Rory McIlroy 2 and 1 to win the World Golf Championships Match Play crown on Sunday, denying the Northern Irishman’s bid to claim the world number one ranking.

Mahan moved 4 up through 10 holes then held off the reigning US Open champion to become the first American to win the title since Tiger Woods in 2008.

McIlroy and Mahan had reached the title match with semi-final victories on Sunday morning. McIlroy roared back from 3 down to beat England’s Lee Westwood 3 and 1, while Mahan never trailed in a 2 and 1 victory over fellow American Mark Wilson.

McIlroy admitted it was tough to bounce back after the tense battle with Westwood — who also had a chance to supplant England’s Luke Donald atop the world rankings by lifting the trophy. “I knew that was going to be the toughest thing for me today, because I was getting myself up for that semi-final match,” McIlroy said.

After McIlroy and Mahan halved the first five holes, Mahan stuck a nine-iron two feet from the pin for a conceded birdie to win the par-three sixth.

That started a run of three straight holes won for the American, who went 4-up by winning the 10th hole, where his approach from 179 yards out nearly found the cup.

McIlroy didn’t win a hole until the 11th, where he chipped in for eagle to lie 3 down.

He rolled in a birdie putt from within eight feet at 14 to trim Mahan’s lead to 2 up.

After they halved 15 with birdies, Mahan had a chance to close it out at 16, where his putt for the title brushed the edge and didn’t drop.

He made the three-footer coming back to halve the hole with McIlroy, whose birdie attempt from 38 feet had stopped less than two feet from the hole.

They were both on the green in two at 17, but McIlroy, needing to win the hole to extend the match, left his 29- foot putt short. Mahan left his birdie attempt from 21 feet about a foot away and McIlroy conceded the tap-in to end it.
