Rose, who shared the 18-hole lead with Tiger Woods, made four birdies on the back nine and holed a six-foot birdie putt on the 18th for a 68.
Woods went the other direction. He a muffed pitch from a bad lie on No. 8 that led to double bogey and had a series of bad swings that put him in bad positions on the back nine and led to four bogeys and put him 6 shots behind. He had to scramble for par on the 18th for a 73, his worst score at East Lake in 14 years.
"I didn't play very good today. Didn't hit it very good, and definitely didn't putt well," Woods said.
Rory McIlroy, who is leading the FedEx Cup and has the best shot at the $10 million bonus, had a 68 and was only 4 shots behind. He was fortunate not to tumble down the leader board: He scrambled for par on three of five holes at the start of his round, but made up plenty of ground with a 40-foot eagle putt on the 15th.
"I just have to try to think of my standing in this golf tournament, not really think about anything else," he said.
Bo Van Pelt made three bogeys on the last four holes and still had a 68 that put him 2 shots behind at 135, along with Masters champion Bubba Watson (66). Dustin Johnson had a 67 and was another shot back, along with Georgia Tech alum Matt Kuchar (69).
Furyk hasn't won since he turned his cap around in the rain, saved par from a bunker, and won the Tour Championship in 2010, along with the FedEx Cup.
