He was at No. 9 in the Ryder Cup standings. Woods briefly led last month's British Open and moved to four-under, just six shots off the lead, after completing his second round on Saturday.
He made a long birdie putt at the next hole, knocked his approach close at the fifth and again at the seventh, then two-putted for birdie at the par-5 eighth. "It's just you can't possibly have firm, fast bent-grass greens with this climate". You don't see that every day. He was playing with Kisner, who shot 29 on the back nine and was in the middle of the ninth fairway - his final hole - needing a birdie to become the first player to shoot 62 in the PGA Championship.
A birdie on the last would have seen Koepka or Schwartzel equal Branden Grace's Major record of 62, set during the third round of The Open at Royal Birkdale previous year. But dropped shots at the 14th and 15th have set the scene for what promises to be an exciting final round. Woods did it in 2000 to join Jack Nicklaus, Ben Hogan and Gene Sarazen as only the fourth player to accomplish that double.
Prior to this week he had made the cut at all three previous majors this year and also won his first title since winning The Open, at the WGC-Mexico, but rounds of 73, 71 weren't good enough.
"I'm in a lot better position than I was when I came out here this morning, which is great", Thomas said.
To get his body ready for Sunday, Woods is likely slated for more ice baths and deep-tissue massages. But I've given myself a shot at winning and I'm excited about that. "I've been so in the zone, you don't know where you are". But after the first three rounds of this event and really the entire season Woods has strung together, it doesn't much matter if he gets it.
Digging even deeper reveals a disparity between even his front- and back-nine scoring: He's 10 (34.75) on the front nine and 120 (35.56) on the back. For the tournament, he is ten under going out and two over coming home.
Woods, whose earlier charge on the easier front nine raised the massive gallery's excitement to fever pitch, was among a logjam of six trailing by four shots.
"I played really well", Koepka said.
Here's a look at some of the standout players to have missed the cut from both sides of the Atlantic and its impact...
He sure didn't damage his chances. He had completed the 11th hold. There the excitement ended for the Northern Irishman.
Schwartzel, the 2011 Masters victor, didn't threaten the lead with his run at 62 but sank a seven-foot birdie putt at the par-3 16th to reach 7-under.
Woods disappointingly closed his back nine with in 35 for a 4-under 66 overall. It nearly goes without saying that until he can find some consistence with his scoring clubs - namely his wedges and his putter - he will continue to fall short in the majors.
