Woods missed a 6-footer for birdie at the seventh hole but when he birdied the ninth, he turned in 31 and was just one stroke back of the leaders.
PGA officials intend to finish 72 holes at the rain-hit BMW Championship even if bad weather takes the U.S. tour's penultimate playoff event into Tuesday, organizers said Sunday.
Tiger Woods, who celebrated his return to the United States Ryder Cup team by earning a share of the lead after the first round, was joint sixth alongside compatriot Webb Simpson on 17-under, while England's Tommy Fleetwood shared eighth place with Tony Finau, Rickie Fowler and Open champion Francesco Molinari.
Final-round tee times at Aronimink Golf Club were originally moved up to 7am in the hopes of beating the weather - but it only ended up meaning an extra long day of waiting for the players. Woods, coming back from injury, made the Tour Championship for the first time since 2013.
Bradley began the day three shots behind Rose but moved up the leaderboard with a six-under-par 64 as Rose shot a 67.
By the end of the day, the tournament came down to three players. His chances to represent USA teams in worldwide play had dried up, his preferred putting method was banned, and the confidence that once put him on the cusp of greatness was shot.
He was tied with Xander Schauffele on the 18th hole of the third round Saturday when Schauffele's 8-foot par putt rimmed around the high side of the cup, giving him a bogey and Rose the lead. Look at the quality of players just outside the top 30, Jordan Spieth among them, and there you'll see what an fantastic year this continues to be for Woods.
For Spieth, it's more than just missing the Tour Championship for the first time. "The quest to get better is what I really wake up for in the morning. and what gets me out of bed".
"I just wish I could have enjoyed the moment maybe, and this just slightly dampens it".
The first tee time was scheduled for 7:30 a.m.
Perhaps most important of all to Woods - the Tour Championship offers another chance for a victory, where he will need to defeat just 29 players.
No one needs to play Monday as much as Spieth.
That means he will have played only 24 tournaments this season. The requirement can be waived if a player competes in 25 events in either the previous or current season. Switching his driver shaft going into the Northern Trust was the last piece of the equipment puzzle, he said.
