CHARLOTTE, N.C. - On a day when the steamy South felt more like late fall in New England, Tiger Woods and Vijay Singh tied for the lead at the Wachovia Championship.

Woods took his only bogey of the round when he drove into the trees on No. 9 at Quail Hollow and had to settle for a 4-under 68. Singh played the final three holes in 3 under to salvage a 71 and join Woods at 6-under 138.

Also tied for the lead was Arron Oberholser, who made birdies on his last three holes for a 69. They had a 1-shot lead over Ted Purdy (69) and Jason Bohn (72).
