Rory McIlroy has bagged a stunning US$15 million pay day by winning a second FedEx Cup title.
McIlroy, the 2016 play-offs winner, carded a four-under 66 at the East Lake Golf Club in Atlanta, to finish at 18-under-par.
His margin of victory four shots - ahead of American Xander Schauffele (70) - at the PGA Tour's season-ending Tour Championship.
Four-time major winner McIlroy was ecstatic to have defeated the big-hitting Brooks Koepka (third), who overcame McIlroy's 54-hole lead to win the WGC-Memphis event last month, and collect the biggest first prize in the sport.
"Going up against the No.1 player in the world today (Koepka), he got one over on me in Memphis, and I wanted to try to sort of get some revenge today," said McIlroy, who moves to No.2 on the world rankings.
"To play like that alongside Brooks and win the FedEx Cup, it's awesome. It's amazing how different things can be in a year."
The Tour Championship win caps a stellar season for the Northern Irishman, who was victorious at the elite Players Championship - which is regarded as golf's unofficial fifth major - as well as the prestigious Canadian Open.
McIlroy appears a lock to claim a third PGA Tour Player of The Year award.
The 30-year-old also finished the PGA Tour season with top-10s in 73.7 percent of his starts - the highest percentage for any player since Englishman Luke Donald posted the same percentage in 2011.
"I think I've given myself so many chances and to win three times is awesome," McIlroy said.
"I feel like I could have won more but to win the FedEx Cup again, to persist the whole way throughout the year, to keep giving myself chances even when I was getting knocked back, I'm very proud of myself.
"I'm going to enjoy this one tonight."
The turning point on Sunday came when world No.1 Koepka, who held an early one- shot lead, lost a ball from an errant tee shot at the seventh hole and made double bogey.
Koepka's final group playing partner McIlroy made a timely birdie on the same hole to steal the lead in a three-shot swing and he never looked back.
