GRAND BLANC, Mich., July 31 (UPI) -- Vijay Singh shot a seven-under 65 Saturday to take the 54-hole lead of the Buick Open.
Singh is at 18-under-par 198 -- two ahead of John Daly.
Tiger Woods, the 2002 champion, posted a six-under 66 and is just three strokes back in his bid for his first stroke-play title since the World Golf Championships last year.
Woods is at 15-under-par 201 and tied with last week's U.S. Bank Championship in Milwaukee winner Carlos Franco, who bogeyed the 18th Saturday to shoot a 67.
"You can't afford to make any bogeys," said Woods, who has only one through three rounds. "To have one is pretty good. I'm starting to play a little better now."
Singh has tried to supplant Woods atop the world rankings and last year topped Woods on the PGA Tour money list.
Singh shared the 36-hole lead with defending champion Jim Furyk and Billy Andrade.
