CHARLOTTE, N.C. -- Arron Oberholser felt like he was going to pass out from the steamy heat. Instead, he passed everyone and wound up alone atop the Wachovia Championship.
As temperatures approached 90 degrees, Oberholser holed a 20-foot eagle putt to jump-start his back nine, then surged past a pack of contenders and left Tiger Woods far behind.
Oberholser finished with a 4-under 68 on Saturday for a one-shot lead and another chance for his first PGA Tour victory.
"I was half in a fog because my blood sugar was so low," said Oberholser, a Bay Area native whose idea of warm is something around 70. "I know the folks around here are like, 'This is nothing.' It's tough on my body."
A three-putt bogey on the 18th left Oberholser at 11-under 205. Geoff Ogilvy matched the best round of the day with a bogey-free 66 and was at 206, along with Notah Begay (69).
Woods was running hot, too, but that had more to do with his temper.
His two-shot lead was gone in 30 minutes, and his swing was not far behind. By the end of the day, Woods resorted to a safe slice off the tee with hopes of keeping the ball somewhere on the property. Even that wasn't entirely successful, and he wound up with a 75 that left him five shots behind.
It was his highest score in 24 previous times when he had the second-round lead.
"I didn't have it at all," Woods said.
Ochoa, Kerr lead LPGA stop
On a windy day when only five players shot under par on the River Course at Kingsmill, Lorena Ochoa and Cristie Kerr grabbed the lead at 7-under 206. Ochoa shot the day's best round, a 3-under 68, and Kerr had a 70 after a finishing bogey.
Ochoa closed with a winding 40-foot par putt on the par-4 18th.
