With a final-round 4-under 66 at East Lake Golf Club, Rory McIlroy overcame a six-stroke deficit to defeat World No. 1 Scottie Scheffler and win the Tour Championship.

Rory McIlroy makes an incredible comeback to win the Tour Championship and FedEx Cup.

By pulling off the biggest final-round comeback in Tour Championship history on Sunday, he beat Scheffler and Sungjae Im by one stroke and finished at 21 under.

What a day and what a week. "Scottie deserves at least half of this today, in my opinion," McIlroy declared. "I kind of feel awful that I beat him to the punch.

By hitting his first tee shot of the competition out of bounds on Thursday and making triple bogey at the first and bogey at the second to fall 10 strokes behind, McIlroy gave him an even bigger advantage.

McIlroy stated, "I got off to the worst start possible. I was thinking of Tom Kim from South Korea, who opened the Wyndham Championship with a quadruple bogey and won.

According to McIlroy, who recovered to shot 67 on Thursday, "anything can happen." "That will be the main thing I remember about this week.

On a hot, sunny day, McIlroy made another mistake at the first hole but recovered by making four birdies in a span of five holes starting at the third.
