Atlanta ? Tiger Woods put together his best back-to-back rounds in more than four years. The result was a share of the 54-hole lead.

Playing his best golf of the year in the season-ending Tour Championship, Woods ran off four straight birdies Saturday at East Lake for a 5-under 65, leaving him tied with 50-year-old Jay Haas.

Woods is ruthless when he has at least a share of the lead going into the final round, with a 30-2 record on the PGA Tour. Trouble is, he hasn’t been there lately.

The last time he held the 54-hole lead was last year at the American Express Championship just north of Atlanta. That was 19 stroke-play tournaments ago, which also is the last time Woods won such an event.

Haas recovered from two early bogeys and shot 68, making a 6-foot par putt on the final hole to join Woods at 9-under 201. They will be paired together, two guys born 22 years apart with nothing in common but a strong friendship.

U.S. Open champion Retief Goosen also made four straight birdies playing with Woods and had the outright lead until he failed to save par from two bunkers on the back nine. He shot 69 and was four shots behind, along with Mike Weir (67) and Stephen Ames (70).

Vijay Singh’s bid to finish the year with 10 victories crashed with an indifferent round of 70 that left him 11 shots out of the lead.
