Rory McIlroy of Northern Ireland became the first three-time winner of the PGA Tour's playoff title with a sterling comeback in Sunday's final round of the Tour Championship at East Lake Golf Club in Atlanta.
McIlroy overcame a six-stroke deficit to slip past number one seed Scottie Scheffler and claim the $US18 million ($26.2 million) first prize.
McIlroy shot a 4-under-par 66 in the final round and ended up at 21 under for the tournament, capturing a one-stroke victory over Scheffler (73) and South Korea's Sungjae Im (66).
