He was joined atop the leaderboard by Brett Quigley. Quigley fired a 6-under 66 and was one of the few players from the afternoon wave of tee times to complete his second round.
The third round is scheduled to start at 11:00 a.m. Saturday with players teeing off split tees in threesomes.
Bo Van Pelt (66) and Jeff Sluman (67) share third place at 11-under-par 133. Joe Durant, Harrison Frazar, Jim Furyk and Robert Allenby all completed their second rounds and share fifth place at 10-under-par 134.
First-round leader Mike Weir, Stephen Ames and Woody Austin are also at minus-10 having completed 15 holes of the second round. Scott Verplank and two-time defending champion Vijay Singh have finished 13 holes of the second round and are also minus-10.
Woods played the front nine first Friday and started with a birdie on the first. He poured in back-to-back birdies from the fourth to move to minus-9.
The world's No. 1 player then birdied the par-3 eighth. Around the turn, Woods ran off three straight birdies from the par-four 12th to get to 13 under. Play was called for the day after he parred the 15th.
Quigley, who is still looking for his first PGA Tour win, got going with consecutive birdies from the first. He picked up another birdie at the seventh to make the turn at minus-10.
The 36-year-old birdied the 10th, but gave that stroke back as he bogeyed No. 13. Quigley atoned for that mistake with a birdie on 14. He collected birdies on 16 and 18 to gain a share of the lead.
Van Pelt carded a bogey-free 66 with four of his six birdies coming on the front nine.
Sluman started on the 10th tee and birdied three of his first six holes. Around the turn, he birdied the first but tripped to a bogey at six. Sluman fought back with consecutive birdies from the seventh to gain a share of third.
Sluman played 30 holes on Friday as the first round was completed earlier in the day. He did so on little sleep as well.
'I woke up at about 2:30 a.m. and have been up ever since,' Sluman admitted. 'I really wasn't feeling well in the morning. We had a nice start so I was pleasantly surprised. I was a little scratchy around the edges.'
Todd Fischer (68) and Charley Hoffman (67) are tied for 14th at 9-under-par 135. Lucas Glover is also at minus-9 through 14 holes of his second round.
