He eventually signed for 66, tied for the second-best round of the day, and his total of 12 under par will give him a two-shot cushion in Round 4.
Woods was among 77 players who returned early on Saturday to complete the weather-delayed second round. The greens would be slightly smoother, the course slightly longer, the approach unchanged - see flag, aim at flag.
Woodland would rather be leading, but in some ways it might be less pressure coming from behind.
Finau played the front nine in 2-under with a pair of birdies, but despite two more birdies on the back side, also had three bogeys, including holes 16 and 18.
In stark contrast, the tee was moved forward to make the par-five 17th play 550 yards and that led to three eagles, 42 birdies and just four bogeys from the 80-man field.
Koepka was at 12-under 198, and even with his major pedigree - the first player with back-to-back U.S. Opens in 29 years - he will play in the final group of a major for the first time. This one missed, and only later did Koepka realize it was for 62. Koepka's sturdy frame seems ready to shoulder the load, but if he falters at all, it should be absolutely bananas at Bellerive with the 100th PGA Championship at stake. I thought I played really clean cards, really clean rounds. "You never know what can happen on the weekend".
That par was the most disappointing of the 10 straight Woods made to finish his third round Saturday at the PGA Championship.
"The greens were getting fuzzy, they're getting slow, and I didn't hit the putts quite hard enough, " Woods said. The only thing they've seen is my struggles and the pain I was going through.
On Friday when Bellerive was virtually defenceless - after thunderstorms halted the second round - those carrying the stars and stripes marched to positions of prominence.
"I just have to make birdies".
He'll be around for two more days of golf. Kisner is not. He relies more on a clean hit with his irons and a great short game.
Showing up to the golf course with a tail might not be for everyone, but Brown was glad to show his support for the competitor everybody's talking about at Bellerive. "But being receptive, that's my only hope".
Ten years removed from his 14th and most recent major title, he displayed shades of his pre-back surgery greatness with a near-flawless front nine on the rain-soaked layout.
Jordan Spieth's chances of claiming the win he needs to complete the career grand slam effectively disappeared as he suffered a nightmare triple-bogey seven on the 12th. After the slow start on Thursday saw him play the first two holes in 3 over par, he has played the remaining 52 holes in 11 under.
He put a handsome swing on it, ending with a pose that would make a flawless photo in a book on golf fundamentals on the page showing what a finish is supposed to look like.
"A little frustrated at this place in general", Spieth said.
