Lee Westwood made 11 birdies in a round of 61 on Saturday and took a share of the third-round lead with Louis Oosthuizen at the HSBC Champions in Shenzhen, China.
Oosthuizen, the 2010 British Open champion, came into the weekend with a five-shot lead but struggled with his putting and had a 2-under 70.
The South African had a chance to retake the lead with a 15-foot birdie putt on No. 18 but missed by inches -- the last of many near misses throughout the day.
Westwood and Oosthuizen were at 18-under 198. Phil Mickelson (66) was three shots back.
Westwood, a former world No. 1, has played in more World Golf Championship events than anyone (41), but his best result is second place on three occasions.
"It does surprise me that I've played more than anyone else. I didn't realize I was that old," the 39-year-old Englishman said. "I know I've played a lot. I've never won one."
As good as his score was Saturday, it wasn't the low round of the day.
That belonged to Brandt Snedeker, who had a chance at a 59 but missed a birdie putt on No. 18 and settled for a 60 and 203 total.
"You don't get a chance to shoot 59 too often, maybe a couple of times in your career," he said. "I'd love to have that putt again."
Champions Tour: Tom Lehman took the lead in the Charles Schwab Cup Championship and moved closer to becoming the first player to win the season points title two straight years.
Lehman birdied the final hole for an 8-under 62 and a one-shot lead over Fred Couples in the season-ending event in Scottsdale, Ariz. Couples also shot a 62, making two eagles.
Lehman was 17 under after three days in perfect conditions at Desert Mountain. He entered the week second behind Bernhard Langer in the points competition for a $1 million annuity. Langer was tied for 10th at 6 under after a 70.
"I played really well the last two days, probably as well as I've played in six months," said Lehman, a two-time winner this year.
Couples is playing for the first time since a back injury forced him to withdraw during the first round of the Boeing Classic outside Seattle in late August.
LPGA Tour: South Korea's Lee Bo-mee shot an 8-under 64 to take a four-stroke lead after two rounds of the Mizuno Classic in Shima, Japan.
Lee, a regular on the Korean tour, had four birdies on the front nine at Kintetsu Kashikojima and added four more after the turn to finish at 10-under 134.
Rikako Morita, who briefly held the lead after an eagle on the par-5 13th, bogeyed three of the final five holes and was in second after a 68.
American Angela Stanford shot 71 and was tied for third at 140 with Na Yeon Choi, Karine Icher and Ayako Uehara.
Etc.: China's Guan Tianlang is one round away from becoming the first 14-year-old to play in the Masters.
He overcame some early nerves at Amata Spring in Bangkok with an even-par 72 to take a two-shot lead over Oliver Goss at the Asia-Pacific Amateur.
The 125-pound Guan was at 14-under 202.
The winner gets an invitation to play in the Masters, along with an exemption to the final stage of qualifying for the British Open.
The youngest competitor in Masters history was Matteo Manassero, who was 16 in 2010.
