The disappointment of not winning the tournament at Aronimink was eased by Rose's rise to the top of the rankings for the first time, where he surpassed American Dustin Johnson.
Rose, like Bradley, failed to par the last in regulation as a 20-footer lipped out and he also bogeyed the hole in the play-off after a three-putt.
And when it finally ended, a day late, with rain still falling on Aronimink Golf Club, it was Bradley celebrating on the 18th green, raising his arms in victory after defeating Justin Rose in a playoff.
The rain-plagued event concluded Monday and Woods made another run at his 80th PGA Tour title, coming up three shots short of a playoff won by Keegan Bradley.
"I'm delighted to be world No. 1", Rose said. "I've been to the top of the game, and that's definitely some consolation. Because for a little while, I didn't know if I was going to be able to get back to this spot, and today I did it".
"I'm disappointed right now". There are no guarantees that the waterlogged course will be playable, meaning the event may be reduced to 54 holes, which Rose would win with a 17-under-par total of 193.

Mayors of barrier islands in the storm's path warned that their communities might get cut off from the mainland. The tropical storm continues to approach the Gulf Coast.
"But obviously it's a big consolation being world No 1". Xander Schauffele was two back, and looked ready to pounce on any opportunity he was given.
"We've got kind of a mess out there", he said. The Englishman could become the world number one with a victory, even if the event were declared complete after three rounds. "It's a dream that we've all thought about at some point in our lives or as young aspiring golfers thinking about it". The body has changed significantly since I first started, so trying to get used to equipment. The process led to setbacks, but he got better each month.
Rose's runner-up finish ensured he would arrive at next week's season-ending Tour Championship in second place in the FedExCup standings, and he is relishing the challenge of attempting to overhaul Bryson DeChambeau and land a $10m bonus as FedExCup champion at East Lake in Atlanta.
"We will do everything we can to play tomorrow (Monday) but we'll just see what Mother Nature gives us", PGA competitions vice president Carlton "Slugger" White said.
