Tiger Woods was 6-under par for the day Sunday at the Farmers Insurance Open and led by six when play was suspended due to darkness.
Woods carded a 3-under 69 in the third round, and was 3-under par through seven holes of the final round to reach 17-under par for the tournament.
Defending champion Brandt Snedeker was 4-under par in his final round and had moved into a share of second at 11-under. He stands alongside Nick Watney, the 2009 winner, who was minus-3 for his final round.
Brad Fritsch, Steve Marino and Casey Wittenberg share fourth place at minus-9.
Phil Mickelson, a three-time winner, shot 3-over 75 in round three and was even-par in the final round. He is tied for 72nd place at plus-2 for the championship.
Fog canceled all but 10 minutes of Saturday's play. The lead groups got through 33 holes on Sunday on the South Course at Torrey Pines, while Woods and his group finished 25 holes.
The final round will resume Monday afternoon at 2:10 p.m. (et).
Woods got off to a quick start in the third round with back-to-back birdies at two and three to push his lead to four. He tripped to a bogey on the fifth, but got that shot right back with a birdie on the par-5 sixth.
Around the turn, Woods birdied the 10th and 13th to extend his cushion to six strokes. He parred four in a row before stumbling to a bogey on the par-5 18th.
Woods' lead was down to four at that point. At the start of his final round, Woods hit his tee ball well left on the first and second, and hit wild drive at four as well. He saved par on the first two holes.
The six-time winner rolled in an 11-footer for birdie at the par-3 third, then chipped in for birdie at the fourth to go five clear of Snedeker and Watney.
Woods 2-putted for birdie on No. 6 to stretch his lead to six for the second time on the day. After his group teed off the seventh, the horns blew to suspend play.
His group all chose to finish the hole. Woods' second stopped 32 feet from the hole and he 2-putted for par.
"Overall, I'm pretty pleased that I was able to build on my lead. As of now, I have a 6-shot lead, so that's a positive," Woods said. "I drove it great in the morning. I just drove it on a string, at least all morning.
"We had a little wait before we teed off again, and I hit it left at one and two, and hit one right at four. I was able to play those holes in 2-under par, and from then on I hit three great drives in a row."
Snedeker, who was in the third group out, mixed five birdies and two bogeys in his third-round 69. In the final round, he scattered four birdies over his front nine to get to 11-under. Around the turn, he stumbled to a bogey at 12, but erased that mistake with a birdie on No. 13 before play was call with him looking at 10-foot birdie putt on the par-4 14th.
Watney poured in four birdies in a 5-hole span from the sixth to jump to 11- under in the third round. However, his run stopped with bogeys at 11 and 12. Watney dropped another stroke at 18 to end round three at minus-8.
At the start of the final round, Watney had three birdies in the first four holes to jump back to minus-11. He parred his next four before play was called for the day.
NOTES: Woods, who led Fritsch by four entering the final round, has won 18 of the last 19 times he owned at least a piece of the 54-hole lead and is 49- of-53 in his career ... The threesome of Luke List, Charley Hoffman and Tom Gillis had a great par-5 13th. Gillis made birdie, Hoffman had an eagle and List holed a 3-wood from 255 yards out for double-eagle ... That was the first albatross of the season on the PGA Tour.
