Play was suspended in the afternoon because of thunderstorms, so the second round will be completed Saturday morning.
While officials sounded the horn just after 3.30pm local time on Friday, Scott had fired a five-under-par 65 at Bellerive Country Club in Missouri hours earlier to earn a 36-hole score of five under.
Australia's Adam Scott and South African Charl Schwartzel, Masters champions who haven't often contended for major titles in recent years, climbed into the hunt Friday at the 100th PGA Championship. After two holes in his first round, he was three-over par.
Woods, however, lamented two bogeys that were the result of makeable par putts from the 5-foot range.
Woods lowest score was a second round 63 en route to victory in 2007 while his highest round was an opening day 77 in 2011, the very first time he missed the cut.
Woodland, who teed off the back side at 8:01 a.m., wasn't about to get caught up in whether his lead would withstand the day with so many players still on the course and others still waiting to start their rounds.
Rickie Fowler, who says he's playing with an oblique strain, is also a 7 under through 10 holes. Organizers said the third round will be played in threesomes and off the first and 10th tees starting 30 minutes after the second round ends.
Woods' back nine was more mixed as he suffered bogeys on 10 and 12, but the 14-time major victor countered that with two further birdies after hitting four on the front nine for a 66, which took him to four under overall.
"And on top of that, if you hit the ball well enough, then you're going to leave yourself in the right sections".
Bellerive is getting battered with low numbers, as the 36-hole cut record of 141 is in danger. Round One leader Gary Woodland shot a four under par 66 to get to 10 under for the tournament and hold on to the lead. "The key is to get the ball in the fairway and attack from there". Kevin Kisner shot a six under par 64 to sit at 9 under par, one shot out of the lead. The golf course is gettable and I'm holing a few putts.
"I feel safe because I feel safe where my game is", Woodland said. "If they were firm, I don't think I would have a chance with the way the greens are situated and the places they're putting the flags". With a front pin on the seventh hole, he went some 25 feet beyond the flag and holed the putt, and then got up-and-down from a bunker on par-5 eighth. "I've been so in the zone, you don't know where you are". I was hitting a lot of drivers.
