He drove the ball with superb control in the third round on his way to a 3-under 69 to build a four-shot lead after three rounds. He lost control with his driver in the fourth round and still managed three birdies in seven holes.
"All we can do tomorrow is go out and try to make him think about it a little bit and see what happens," said Nick Watney, one of two former winners at Torrey Pines who faced the tough task of trying to make up six shots on Woods.
The other was defending champion Brandt Snedeker.
"I've got a guy at the top of the leaderboard that doesn't like giving up leads," Snedeker said. "So I have to go catch him."
Woods was at 17-under par for the tournament and will resume his round on the par-3 eighth hole.
Snedeker played 13 holes of the final round. Watney played eight holes. Both were at 11-under par.
Woods played seven holes of the final round. He started with a two-shot lead and tripled it before darkness suspended play.
"It was a long day ... and I played well today," Woods said. "Overall, I'm very pleased that I was able to build on my lead."
Thick fog washed out all of Saturday, forcing players to go from sunrise to sunset Sunday. They finished the third round, took about 30 minutes for lunch and went right back onto the golf course.
Woods finished 54 holes at 14-under 202 and was four shots ahead of Canadian rookie Brad Fritsch. It was the 16th time in his PGA Tour career that Woods had a 54-hole lead of at least four shots.
Snedeker was seven shots behind after three rounds, the same deficit he faced a year ago. Only now he's trying to chase down Woods, already a seven-time winner at Torrey Pines with a daunting record from in front. Woods is 38-2 on the PGA Tour when he has the outright lead going into the last round.
"I've got to make some more birdies," Snedeker said. "I've got a long way to go."
