Jordan Spieth capped a brilliant season in sensational style as he scored a four-shot victory at the Tour Championship on Sunday that also won him the FedExCup playoffs title for a $10m bonus and an overall pay day of $11.48m.
Spieth shot a closing one-under-par 69 at East Lake Golf Club for a nine-under total of 271 and his fifth win of the season, including the Masters and US Open.
The prize money haul included the $10 million jackpot bonus for winning the season's FedExCup points competition and virtually clinched him Player of the Year honours.
With Jason Day finishing joint 10th, the victory also took the 22-year-old above the Australian and Rory McIlroy to the top of the world rankings.
Spieth carded a closing 69 at East Lake to finish nine under par, four shots clear of Henrik Stenson, Justin Rose and Danny Lee.
"This is incredible. This is an event that we approach like a Major championship because we know this is possible at the end of it," said Spieth afterwards.
"I got frustrated. I missed two cuts in a row, had never done that, lost the number one ranking. I was watching Jason Day just dominate golf," said Spieth.
"I got to work, put my head down a little more than I did right after the PGA, knowing that we could still peak this week and that's what we did."
Spieth took a one-shot lead over Stenson into Sunday's final round and had doubled his advantage by the turn, although the 22-year-old was not having it all his own way.
The Masters and US Open champion, who was also fourth in the British Open and second in the US PGA, initially moved two shots clear by holing from 10 feet for birdie on the second, but then failed to get up and down following a poor approach to the fifth and followed that error with a three-putt bogey on the sixth.
After depositing the offending ball into the lake which surrounds the green, Spieth quickly regained his composure and holed from 20 feet on the eighth as playing partner Stenson made bogey after finding trees off the tee and a bunker with his approach.
It looked as though Stenson would reduce the gap to a single shot after leaving himself a tap-in for birdie on the par-five ninth, only for Spieth to hole from 18 feet.
The final pair both bogeyed the 10th before Spieth, who had described his short game as "magic" on Friday, produced more evidence to back up such claims.
With Stenson again within a few feet of the hole on the 11th, Spieth holed a curling birdie putt from 45 feet to maintain his two-shot cushion, Stenson looking at the American with a mixture of admiration, resignation and no doubt more than a little irritation.
A bogey from Stenson on the 12th then eased the pressure on Spieth, who crucially saved par on the 15th from eight feet after Stenson left his long birdie attempt inches short.
Stenson had held a three-shot lead after 36 holes and his miserable weekend was capped off by a dreaded shank on the 17th which resulted in a double-bogey six, although the 39-year-old did at least hole from almost 60 feet across the 18th green for a closing birdie.
McIlroy finished on one over par in a tie for 16th after carding a final-round 74.
After birdieing the 16th the Holywood man double-bogeyed the par-five 17th to finish his weekend on a disappointing note.
