But it was another round that featured a couple of big mistakes that cost Woods a chance of posting a really low number.
"It was kind of a mixed bag as far as the results, but the fact I had total control of the golf ball was nice," he said after making six birdies and three bogeys.
Woods hit 11 of 14 fairways, 15 of 18 greens and took 29 putts on a hot and sunny day along Lake Manassas.
Unlike the first three days, his round didn't feature any nasty hooks off the tee. And, yes, that can be considered progress for a guy with 14 majors.
But perhaps more importantly, Woods said after four rounds at Robert Trent Jones Golf Club he feels like he's turned a corner with his new swing under instructor Chris Como.
"I'm getting some speed back, which is nice," he said. "I'm starting to pump the ball out there again, and I know the lofts on my irons are very weak compared to today's standards. I'm hitting the ball up there with some of the bigger guys again ... I was able to make some putts, and the short game's becoming good again like it used to be."
Starting the day nine strokes off the lead, Woods got the crowd going with birdies on 3, 4 and 5, and then he raised the putter on the par-3 9th after dropping a 42-foot putt for birdie to make the turn at 9 under and five strokes back.
He continued the charge with a birdie on the par-4 10th to reach double digits, but his 3-foot par putt on the par-3 11th spun around the hole for a momentum-killing bogey. He dropped another shot at 12 when his drive found the pond right of the fairway. And on the par-5 14th he got one more punch to the stomach when his third shot spun back into the water for yet another bogey.
Woods hit the ball solid coming in and added a birdie on 17, but he was tied for 21st when he finished on a weekend that could have turned his season around.
The tournament host would have punched a ticket to next week's WGC-Bridgestone Invitational with a win here, and he could have gotten into the FedEx Cup playoffs.
"It's a great golf course," he said. "Pete Dye intimidates you with the visuals out there, but he gives you a lot more room than you think."
