Rory McIlroy gave an impressive performance on the course and expressed his unwavering backing of the PGA Tour off it.

McIlroy became the first three-time winner of the FedEx Cup with a stirring comeback in the final round of the Tour Championship at East Lake Golf Club in Atlanta on Sunday.

He overcame a six-stroke deficit to slip past No. 1 seed Scottie Scheffler and claim the $18 million first prize.
