Forget college football: The best battle for No. 1 might be taking place on a golf course outside of Boston.

Vijay Singh -- the No. 2 golfer in the world -- shot 63 yesterday to move to 11 under par and take the second-round lead in the Deutsche Bank Championship in Norton, Mass. With an eagle on the first hole sparking the best round of the tournament, he took the lead from top-ranked Tiger Woods with back-to-back-birdies on Nos. 12-13 and moved into position to take Woods's No. 1 ranking, too.

"It's not going to affect me one way or another if I overtake him," said Singh, who has already won five times this year, including the PGA Championship. "Yeah, if I win this tournament, I'll be number one. Fine. But what would that change for me? I'm going to go out there next week and do it all over again."

Billy Haas and John Rollins were tied with Woods at 9 under, two strokes back, with Ryan Palmer and Shigeki Maruyama at 8 under on the par-71, 7,415-yard TPC of Boston course.

Woods has held the No. 1 ranking for a record 264 consecutive weeks. Singh would take it over if he finishes higher than Woods or, if Woods finishes lower than a tie for seventh, Singh would come out of the weekend No. 1 no matter what.

"The number one ranking takes care of itself just by winning tournaments," Woods said. "If you win consistently, you don't have to worry about that."
