Tiger Woods shot a 6-under-par 66 yesterday at the Buick Open in Grand Blanc, Mich., and still lost ground to Vijay Singh.
Singh shot a third-round-best 65 for an 18-under 198 and a two-stroke lead over John Daly, who shot a 66.
Woods started the day trailing by two shots, and despite six birdies and no bogeys, he fell another shot back and is tied for third with Carlos Franco at 15 under.
Defending champion Jim Furyk and Billy Andrade, who shared the second-round lead with Singh, struggled. Furyk shot a 70, and fell into a tie for sixth. Andrade was 1 over and will start the final round tied for 11th.
Singh, who trails only Woods and Ernie Els in the world rankings, has three victories this year and 10 top-10 finishes. But since winning consecutive tournaments three months ago, he has just two top-five finishes and was tied for 28th at the US Open and 20th at the British Open.
The Fijian is playing well this week after changing his putter -- and focus. He went back to a standard putter after using a long one for 2 1/2 years. He also stopped worrying about chasing Woods in the world rankings, as Singh acknowledged he did earlier this year.
Daly has a shot to win two tournaments in one year for the first time, and a victory would shoot him into contention for a spot on the Ryder Cup team. He won the Buick Invitational six months ago, but hasn't had a top-10 finish since April.
LPGA/European -- Annika Sorenstam overcame two double bogeys to stay in the hunt at the Women's British Open and Minea Blomqvist of Finland surged into contention with the lowest score ever in a major. Sorenstam offset double-bogey 7s at Nos. 1 and 14 with five birdies in a 2-under 70, moving to 7-under 209 through three rounds on the Old Course at Sunningdale. She's five strokes behind co-leaders Heather Bowie and Rachel Teske, who shot 65s and moved to 12-under 204.
The biggest move of the day came from 19-year-old Blomqvist, who made a 60-foot birdie putt on the final hole for a 10-under 62 -- the first in a major. Blomqvist had six birdies and two eagles, breaking the tournament record of 63 set three years ago by Karrie Webb at Turnberry. She also broke Webb's course record of 63 set in 1997.
Champions -- Craig Stadler birdied three holes in a five-hole stretch to shoot a 69 and catch Peter Jacobsen, who shot 70 and shared the lead at the US Senior Open with a 7-under 135. Jose Canizares was at 6 under, making birdie on the final three holes for his second 68 at Bellerive Country Club in St. Louis. Because rain washed out play Friday, the field will play two rounds -- 36 holes -- today, with the forecast calling for a muggy 91 degrees. European -- Luke Donald shot a 3-under 69 to take a three-shot lead after the third round of the Scandinavian Masters in Loddekopinge, Sweden. Donald is at 13-under 203 on the Barseback Golf and Country Club, and could have taken a bigger lead into the final round if not for bogeys on the final two holes. Peter Hanson was at 206 after a third-round 68.
