UPDATE 1-Golf-McIlroy pockets $15 million after winning Tour Championship and FedEx Cup

Rory McIlroy won the Tour Championship and the FedEx Cup in style in Atlanta on Sunday, collecting the biggest first prize in the sport, $15 million.

Northern Irishman McIlroy emphatically outduelled Americans Brooks Koepka and Xander Schauffele with a four-under-par 66 in the final round at East Lake. He finished at 18 under par, four shots ahead of Schauffele to claim the season-long FedEx Cup points competition for the second time on the PGA Tour, after his 2016 win.

It was a sweet stroll up the final hole for McIlroy, who last year had to make the walk alongside a victorious Tiger Woods as the heaving gallery chanted, "Tiger, Tiger." This time the chants were for McIlroy.

"It was pretty cool," McIlroy said in a greenside interview. "I must say I didn't enjoy that walk last year like everyone else did. I never took the fight to Tiger.

"It's amazing how different things can be in a year." McIlroy took the fight to Koepka just four weeks after being given a lesson by the American when they were paired in the final round at a World Golf Championships event in Memphis.

"Going up against the number one player in the world today, he got one over me in Memphis and I wanted to get some revenge," McIlroy said. "To play like that alongside Brooks, get the win, win the FedEx Cup, it's awesome."

Schauffele shot a closing 70, while Koepka was unusually error-prone in a 72 to tie for third with Justin Thomas, five shots behind.
