Hunter Mahan won the Phoenix Open in Scottsdale, Ariz., for his second PGA Tour title, coming from four strokes back to beat Rickie Fowler by a shot in a 1-2 finish for former Oklahoma State players.

Mahan, 27, had an eagle and two birdies in a late four-hole span Sunday to finish at 16-under 268. Mahan, who also won the 2007 Travelers Championship, closed with consecutive, bogey-free 6-under 65s.

He is the eighth U.S.-born player still in his 20s to win more than one tournament.

Fowler, 21 and a tour rookie, had a final-round 68 for the second runner-up finish of his young career, both of them in Arizona.

In his second PGA tour event in October, Fowler lost in a three-way playoff to Troy Matteson in the Frys.com Open down the road at the Grayhawk Golf Club.

South Korea's Y.E. Yang also shot a 65 to finish at 14 under, two off the pace. Last year's PGA Championship winner, Yang led until his tee shot went in the water at No. 17.

Mathew Goggin, Chris Couch and Charles Howell III tied for fourth at 13 under.

Third-round leader Brandt Snedeker struggled mightily at TPC Scottsdale with a 78 to wind up at 7 under.

Heavy rain fell overnight at TPC Scottsdale and sprinkles lingered in the morning. But the rain subsided by the time the leaders teed off at noon.

The tournament, in its 75th year, was known as the FBR Open but returned to its longtime Phoenix Open name when Waste Management Inc. took over as the title sponsor this year.

The poor weather held the estimated final-round crowd to just under 44,000, well off last year's 60,000-plus. That brought the week's total attendance to nearly 426,000, down from 470,000 a year ago at the rowdy event that always draws the biggest crowds on the tour.

Going down the stretch, it was a three-way battle with Mahan, Fowler and Yang.

Yang, whose PGA Championship victory made him the first Asian-born golfer to win a major, eagled No. 10, then reeled off four consecutive birdies to take the lead at 15 under through 15 holes. Trouble came, though, at No. 17, where his tee shot bounced into the water. Yang's 25-foot putt for par was on line but stopped an inch short of the cup, and the bogey left him at 14 under.

• HSBC Champions: Ai Miyazato won in Singapore to become the first LPGA Tour player in 44 years to sweep the first two events of a season, closing with 3-under 69 for a two-stroke victory over Cristie Kerr (68). Miyazato, 24, a Japanese star who won the LPGA Thailand a week ago, took the lead with a birdie on the par-4 16th and parred the final two holes to finish at 10 under. A 15-time winner on the Japanese tour, Miyazato earned $195,000 for her third career LPGA Tour victory -- all outside North America. She won the Evian Masters last year in France for her first LPGA Tour title.
