Rose has as a result reclaimed his world number one ranking after emerging as a winner in the Turkish Open.
The 38-year-old handed out defeat to Li Haotong of China in a play-off after both finished on 17 under par.
And that was also for him to achieve his 19th career win while returning to the top of the rankings.
He initially made it there in September, 2018 and holding the position for seven days before Brooks Koepka replaced him.
This is the first time ever Rose has defended a tour title after winning in Belek in the year 2017.
Rose, an ex-US Open winner posted a final round of 68, three under par to finish at par with Li.
And that was on the Regnum Caya course before the 23-year-old Chinese man bogeyed the extra hole in the play-off.
Li had actually gone ahead to have the lead by three shots heading into the last day.
Rose in great delight following FedEx Cup success
England’s world number one, Justin Rose says he is presently in great delight following his success in the FedEx Cup.
Rose whose only 2018 PGA Tour victory was at the Forth Worth Invitational in May entered the tournament’s play-offs fourth.
And that was on the points list behind the trio of three others, Dustin Johnson, Justin Thomas and Brooks Koepka.
After missing the Northern Trust competition, he finished second in both the Dell Technologies Championship and the BMW Championship.
Rose, Tony Finau, Johnson, Bryson DeChambeau, defending champion, Thomas and Woods all came into the Tour Championship.
And that was with an opportunity to pick up the FedEx Cup bonus with a win at East Lake.
With Woods looking almost very certain to win the tournament, a top-five finish for Rose was going to be enough.
And that was for the world number one to come out as the overall title winner.
However, bogeys on the 11th, 14th and 16th saw Rose make a drastic fall from the top five.
And Woods was then set to go ahead and secure the FedEx Cup in addition to the Tour Championship.
Rose, 38, required a birdie on the par-five 18th to finish joint fourth with Japan’s Hideki Matsuyama, claiming the title.
