Shenzhen, China • Ian Poulter won the HSBC Champions on Sunday for his first victory of the season, overcoming a four-stroke deficit with a 7-under 65.
The English Ryder Cup star finished at 21-under 267 on Mission Hills' Olazabal Course for a two-stroke victory. The victory was his second in World Golf Championship play, following the 2010 Accenture Match Play Championship.
"I've only been one season without a victory and I certainly didn't want to go another one," the 36-year-old said. "As well as I've played this year, it would have been a disappointment personally to have gone that year without winning."
Phil Mickelson (68), Jason Dufner (64), Scott Piercy (65) and Ernie Els (67) tied for second. Lee Westwood and Louis Oosthuizen, tied for the third-round lead, shot 72 to drop into a tie for sixth at 18 under.
In Scottsdale, Ariz., Tom Lehman won the Charles Schwab Cup Championship to become the first Champions Tour player to win the season points title two straight years. After taking a one-stroke lead into the final round, Lehman birdied four of the last five holes for a 5-under 65 and a six-stroke victory.
Lehman finished at 22-under 258 on Desert Mountain's par-70 Cochise Course to break the Champions Tour record for the lowest numerical score in a 72-hole event. Jack Nicklaus set the previous record of 261 at par-72 Dearborn Country Club in Michigan in the 1990 Mazda Senior TPC.
Jay Haas shot a 69 to finish second, and St. George's Jay Don Blake shot a 66 to finish third, at 14-under par 266.
In Shima, Japan, Stacy Lewis rallied to win the Mizuno Classic for her LPGA Tour-leading fourth title of the year, birdieing the final three holes for an 8-under 64 and a one-stroke victory. The Texan, seven strokes behind South Korea's Lee Bo-mee entering the round, had 10 birdies and two bogeys to finish at 11-under 205 at Kintetsu Kashikojima.
