played the best round of an already impressive career with an 8-under 63 on Sunday to win the Australian Open by 6 strokes in Sydney, making his first trip Down Under a successful one.
Spieth's 72-hole total of 13-under 271 at the tough, windy Australian Golf Club made him the first American to win the Australian Open since Brad Faxon in 1993, when the 21-year-old Spieth was 4 months old.
Spieth birdied four holes on the front nine - three of them in a row - to lead by 3 strokes after nine holes, then made light of the challenging, windy conditions by adding four more on the back nine, never threatening to lose his lead.
Adam Scott shot 71 and finished fifth, 9 strokes behind. Defending champion Rory McIlroy, who shot 76 on Saturday, finished with a 72 and was 2-over, 15 strokes behind Spieth.
