He laid up, then speared a majestic 150-yard wedge to within three feet.
Woods shot five-under 66, while Norris carded a respectable two-under 69 in an atmosphere unlike any other he had experienced before. "You're in a scenario nearly like the U.S. Open this year at Shinnecock, like that Saturday at the U.S. Open-type scenario".
However, the 14-time major victor immediately posted back-to-back birdies to return to level par where, after going bogey-birdie immediately after the turn, he remained through 12 holes.
Tommy Fleetwood-inspired British hooligans take shifts throughout the night playing ding-dong-ditch and leaving flaming bags of excrement, Billy Madison-style, on the front porch of the "frat house" that's home for several contenders this week, leaving sleep-deprived co-leaders Spieth and Kisner off their game.
As he finished and walked off the green at No. 18, playing his third major this season after missing eight in a row, the man who has won 14 major titles but none since 2008 looked absolutely younger than his 42. He is even par overall.
Three-time major victor Rory McIlroy is a shot further back after a second successive round of 69 but it was a score that was compiled in a very different manner.
Then there is Tiger Woods, who shot 66 Saturday, at 5-under and tied for sixth with a list of players including Rory McIlroy, Zach Johnson, Tommy Fleetwood, Matt Kuchar, Webb Simpson and Alexander Noren. His presence creeping up the leaderboard nearly overshadowed the fact Spieth has positioned himself to become the first player to defend his Open Championship title since Padraig Harrington did it in 2007-08. He missed an 8-footer on No. 5 for the outright lead.
Scoring conditions were ideal on a warm day with little wind and greens softened by rain the day before.
First, Justin Rose set the tone with a stunning 64. Woods hit six birdies, with only a bogey at the 16th dampening his charge.
It is also the first time he has led at any point of a major since 2012, when he shared the 36-hole lead at the PGA Championship.
When a 25-foot birdie putt trundled across the ninth green and into the cup things to get very interesting. He made double bogey for a 70 that cost him a two-shot lead, but not his outlook. I didn't want to be too far back if the guys got to 10 [under] today.
Woods trails Jordan Spieth, Xander Schauffele and Kisner by four shots. "I didn't let the conditions get to me". Kisner and Chappell have a 9:35 a.m. tee time.
It could also lead to early players leapfrogging over the group of players - and there are seven in all - tied with Woods for sixth place and making it even more hard to move up the leaderboard. Even fellow golfers were excited for him, with Ian Poulter describing Woods joint leader as the "stuff dreams are made of".
"Walking up, I thought I was in big trouble, no swing, right in the trees, based on the way the crowd was moving around the tree", Spieth said.
