Hunter Mahan stopped Rory McIlroy’s march to No. 1 by winning the Match Play Championship on Sunday in Marana, Ariz.

Mahan won four holes in a five-hole stretch starting with a 9-iron to 2 feet on the sixth hole, building a 4-up lead through 10 holes. Even as McIlroy threw his best stuff at him on the back nine, Mahan responded with two clutch birdies to stay in control.

Mahan won, 2 and 1, to capture his second World Golf Championship title.

“[McIlroy’s] the best player in the world right now,” Mahan said. “I knew he’d made a charge, and he did.”

McIlroy defeated Lee Westwood in the semifinals Sunday morning, a high-stakes match because if either of them won the Match Play Championship, they would replace Luke Donald atop the world ranking.

Mahan made sure that didn’t happen this week.

He played 96 holes in his six matches and had 35 birdies on his scorecards. Mahan defeated Mark Wilson in his semifinal match — Wilson was his only opponent all week who had not played in a Ryder Cup or a Presidents Cup.

McIlroy, who made seven birdies in a 10-hole stretch Sunday morning to beat Westwood, couldn’t muster any magic in the afternoon. He missed a 4-foot par putt that would have won the opening hole, then fell behind with a series of mistakes.

On the seventh hole, with Mahan already in trouble in a deep collection area left of the green, McIlroy pulled his short iron and joined him there. But it took McIlroy two chips to get on the green, and he lost the hole with a double bogey.

Then McIlroy’s sand wedge hopped over the green on the par-5 eighth and he lost that hole with a bogey.

Mahan’s big lead was enough to withstand the McIlroy charge. The 22-year-old from Northern Ireland played the opening six holes on the back nine in 5-under par, but still picked up only one hole on Mahan.

Mahan probably will go to No. 9 in the world. He earned $1.4 million.

PGA Tour

John Huh parred the eighth hole of a playoff to beat Robert Allenby and win the Mayakoba Golf Classic in Mexico.

The 21-year-old Huh parred all eight holes in a playoff that matched the second-longest in PGA Tour history.

Huh closed with an 8-under 65 to match Allenby at 13-?under 271 on the seaside El Camaleon course. Allenby had a two-stroke lead with a hole to play in regulation, but the 40-year-old Australian drove into the trees on the right and made a double bogey.

The playoff ended on No. 10 when Huh, seven strokes behind leader Daniel Summerhays after three rounds, chipped from the right rough to 2› feet and made his par putt. Allenby drove into the hazard on the right, chipped to 15 feet and missed his par try.

Matt Every and Colt Knost shot 66 to tie for third, two strokes back.

LPGA Tour

Angela Stanford won the HSBC Women’s Champions in Singapore on the third playoff hole, her first victory since 2009 and her fifth on the LPGA Tour.

The 34-year-old Texan parred the last playoff hole, beating South Koreans Jenny Shin and Na Yeon Choi and China’s Shanshan Feng.

Stanford, who earned $210,000 for the victory, trailed Shin by a shot after the 17th when play was delayed about 90 minutes because of lightning. When play resumed, Shin hit her tee shot out of bounds, leading to a double bogey. Stanford bogeyed No. 18 to fall into a four-way tie at 10-under 278.
