Defending champ Keegan Bradley, with a 71, was another shot back along with Miguel Angel Jimenez, who put up a 65. Rounding out the top 10 were 2011 Bridgestone winner and reigning Masters champ Adam Scott and Zach Johnson.
Woods has overwhelmed everyone in a glittering field that includes 48 of the top 50 players in the world ranking.
Much like he did a day earlier, Woods started out fast. He birdied the first two holes (he had also eagled No. 2 in the second round). He rolled in a 12-footer at No. 1 and then two-putted from 40 feet at No. 2, most likely causing the rest of the players to just shake their heads.
From there, however, he proved merely human. He parred the next six holes and then drove into the sheer face of a fairway bunker and took a bogey at the ninth hole.
He played the back nine 1-under par — including yet another shot for the highlight reel.
At the par-4 13th, he airmailed his iron shot over the green and into heavy, grabby rough. But he got a sand wedge under the ball, popping it straight up. It landed on the green and rolled right to the pin, clanging off it and into the hole for birdie from 40 feet away.
"Certainly, it wasn't a shot I was trying to make. I was just trying to get it down there where I could get a par and get out of Dodge and dodge a bullet," he said. "It just happened to go in."
Of course, the ball often happens to just go in for Woods at World Golf Championship events like the Bridgestone.
He has won 17 times in 41 starts — a success rate of 41 percent — while finishing in the top 10 an amazing 32 times in WGC events.
At Firestone, he's had winning streaks of four (2005-09) and three (1999-2001), and also has a tie for second and two fourth-place finishes.
Woods looked back on his round and gave it a thumbs-up.
"It ended up being a dead push for the day," he said about hanging on to the same lead he began the day with. "That's not too bad, either."
Not too bad at all.
