Rory McIlroy, 27, edged out play-off opponent Ryan Moore, 33, with a birdie on the fourth hole to seal his victory in Atlanta, resulting in the Northern Irishman winning the FedEx Cup, the PGA's season-long points competition.
McIlroy pipped US Open Champion Dustin Johnson, 32, to the post, with the American posting a score seven shots off the lead at East Lake Golf Club.

He said: "I couldn't control what anyone else did. I needed to come out here and play a really good round of golf. I just wanted to go out and play the way I have been playing."
"I feel my game is really coming together at the right time, and two wins in the last three feels pretty nice."
McIlroy's fight to get in contention for the FedEx Cup was worthy of any championship title.
He looked down and out with just three holes to play, three off the pace, but a spectacular 137-yard eagle drove him straight back into the contest.
After a closely fought play-off, that saw both McIlroy and Moore play some sensational golf, McIlroy won the championship, producing a fine birdie to down his determined opponent.
It's fair to say that he was pretty happy with his win, especially if his celebration is anything to go by.
What a finish to a brilliant tournament.
Great timing too, as this surely leaves McIlroy with a great amount of confidence heading into the Ryder Cup, which begins September 30.
