Not even one bad hole could keep Tiger Woods from a share of the 36-hole lead for the first time in more than five years.
Never before has Woods failed to convert when he had such a big advantage through three rounds.
Rory McIlroy, who will join Woods in Sunday's final group, and Justin Rose are his closest pursuers.
Woods was in the middle of a sparkling third-round at The Tour Championship when his odds at the Westgate SuperBook in Las Vegas shortened to 9-1, making him the favorite to win the Green Jacket in April. "That helps. I don't have to shoot 63 or 64 and hope I get help".
There were days during Woods's prime when we could all have gone home at this point, knowing exactly what would happen in the final round.
But even with the wattage lighting the top of the leaderboard, it is not a question of who will win this tournament but rather, more simply, whether or not it will be Woods.
Barring a Sunday bottoming-out that other guy will nearly surely claim this year's FedEx Cup, as even a Woods victory will not be enough to close the gap that now has him 20th in the standings. Bryson DeChambeau, the No. 1 seed, shot 75 and was 13 shots behind.
Paul Casey, Tony Finau and Billy Horschel are seven off the lead on five under.

It warned that prices could rise above $80 unless producers compensate for lost supply from OPEC members Iran and Venezuela. China, one of the world's largest oil consumers, on Tuesday added $60 billion of US products to its import tariff list.
Also vintage was Woods's reception, an outpouring chorus of support that greeted and trailed him on either end of every shot. A flip wedge to 12 feet and two putts later, he was back in a tie with Rose.
Rose is coming off a playoff loss at the BMW Championship last week, and as the No. 2 seed in the FedEx Cup is in the best spot to win the $10 million bonus. It was a misplayed chip late on the back nine at The Open and a collection of missed putts at the PGA Championship, although in his defense it's unlikely anyone could have caught Brooks Koepka at Bellerive.
'It's the flawless place for me to open my campaign, ' he said in January, 'but the landscape has shifted dramatically.
"Simple math says that if I play a clean card, the guys behind me have to shoot 67 to force it into extra", Woods added.
"It's obviously exciting for the tournament, it's exciting for golf in general that he's up there but for me, all I can do is concentrate on myself". The game is hard enough without having to. without looking at other people. "Go out there and take care of my business and hopefully that's good enough".
Woods has the 54-hole lead for the first time since his last victory in 2013 at the Bridgestone Invitational. He opened with a 62 at Aronimink two weeks ago on a rain-softened course and stayed within five shots of the lead the rest of the way until he tied for sixth.
"I was still trying to figure out how to play", he said.
