Bradley, 32, outlasted newly-minted World No. 1 Justin Rose to win the BMW Championship, the third leg of the FedEx Cup Playoffs.
Rose, who reeled off nine consecutive pars to finish round three on Saturday after an outward nine of 29, also finished runner-up in this event past year albeit at another venue. Play was also suspended Saturday morning as players watched rain pelt the course.
Tiger Woods, meanwhile was five shots behind after a 66 in the third round that didn't allow him to make up any ground on the lead.
Rose could have won in regulation but lipped out on the last hole to force the playoff.

At the 425-yard par-4 11th, Cantlay got on in 2 and missed his par putt from 5 feet, finishing with a 3-putt bogey.
Bradley two-putted from just off the green for the victory, which sees him jump to 6th in the FedEx Cup standings.

"We are trying to play today and if we do play and happen to get finished so be it but the weather doesn't look promising", White said.
Keegan Bradley is 30th and would be exempt for the first three major championships in 2019.
"I just wish I could have enjoyed the moment maybe, and this just slightly dampens it".
"I'm very proud of it, it's been a good stretch of golf, I've really played solidly for over a year".
The first tee time was scheduled for 7:30 a.m.
"It's a game changer for a player like me that's not in the top 50 to get in the Tour Championship", he said. This year he did not add a new event, and the Ryder Cup - which counts - will give him just 24. They are exempt from the policy by playing 25 events.
"I obviously accept whatever fine it is and move on and try and add one every year, but it's kind of tough", Spieth said.
