An emotional Tiger Woods completed an astonishing comeback to win the season-ending Tour Championship by two shots and record his first win in five years.
The 42-year-old's victory in Atlanta was his 80th PGA Tour title - only fellow American Sam Snead has more - but his first since August 2013.
Less than a year ago he was 1,199 in the world after spinal fusion surgery - the latest of multiple operations.
"I was having a hard time not crying on that last hole," Woods said.
"I just can't believe I've pulled this off."
Thousands of fans spilled on to the 18th fairway to follow Woods to the green chanting "U-S-A" and "Tiger, Tiger" after his approach found a bunker on the edge of the green.
Woods holed out for par to complete a final round of 71 for an 11-under total before holding his arms aloft in celebration of a brilliant win just days before the Ryder Cup gets under way in Paris.
England's Justin Rose lost his world number one ranking as a result of finishing tied fourth but secured the overall FedEx Cup which determines the season-long PGA Tour champion - the first Englishman to do so.
Rose birdied the 18th at East Lake for a 73 to finish on six under and seal the top-five finish he needed to win the $10m (£7.6m) bonus on offer as FedEx Cup champion.
'I loved every bit of it'
Woods, who was two clear of compatriot Billy Horschel, said: "I had to suck it up and hit some shots. Once I got the ball on the green, it was done. I could handle it from there."
The 14-time major champion's last tournament victory was in August 2013 at the WGC-Bridgestone Invitational, since when he has had surgery on his back four times
"It was just a grind out there," Woods added. "I loved every bit of it, the fight, the grind and the tough conditions.
"At the beginning of the year, it was a tall order but as the year progressed and I proved I could play, I knew I could do it again."
He came into the final day of the tournament - the last of four FedEx Cup play-off events - with a three-shot lead over Rose and Northern Ireland's Rory McIlroy, who faded from contention with a 74 to finish on five under in a tie for seventh.
Woods birdied his first hole - one of two birdies and three bogeys - with his place at the top of the leaderboard in little danger during the final round.
"It's been tough. I've had a not-so-easy last couple of years," he said. "I've worked my way back. I couldn't have done it without the help of all the people around me.
"Some of the other players knew what I was struggling with. It was really special to see them at the green on 18. It's just hard to believe I won the Tour Championship."
