Woods led throughout the final round and finished at 11-under-par 269 at East Lake, where he carded a closing 71 for his 80th PGA Tour victory. Justin Rose of Great Britain, on the strength of a 18th hole birdie, won the FedEx Cup playoffs, making him the season-long champion of the PGA Tour.

His season-ending Tour Championship victory sent social media into frenzy, much like it had the raucous crowd around the 18th green.
Woods' 2018 season was nearly inconceivable previous year. But by the end of the tournament, Woods' odds had been trimmed to 9-1, ahead of Spieth's, at the Westgate SuperBook in Las Vegas.
"I guess it's different now because the art of clapping is gone, right?"
Woods opened with a birdie, while Rory McIlroy made bogey from the bunker on the fourth hole.
"The up and down at 17 was huge", added Woods, who was flying to Paris later Sunday with the U.S. team for week's Ryder Cup.
Tiger Woods seized the headlines and ended five years of frustration Sunday by winning the Tour Championship by two strokes over Billy Horschel. In order to win the cup, he needed to win the event - which was close to a lock all day - and Rose needed to finish in a three-way tie for fifth or worse.
