Jordan Spieth wins the Emirates Australian Open

Jordan Spieth used a course-record 8-under 63 Sunday to separate himself from the pack at The Australian Golf Club and win the Emirates Australian Open by six shots.

 "It's the best round I have ever played, especially considering the conditions," Spieth told the Associated Press. "It was just kind of one of those rounds when you're in the zone and you're not sure what you're at. It's nice that it came on a Sunday.

"Being able to spread out from the field was a pretty awesome experience. I didn't think the round was out there but the putts just kept going in. Boy, we had a good time out there today."

Spieth, who finished at 13 under in Sydney, entered Sunday's final round tied for the lead at 5 under with Australians Greg Chalmers and Brett Rumford.

Spieth, 21, shot the best round of the day by four strokes, going bogey-free for his second professional win. He became the first American to win the event since Brad Faxon in 1993. His round came as a record for the course that was recently redone by Jack Nicklaus. It was being played as a par 71 for the first time in a professional event.

Rod Pampling carded a 3-under 68, taking second at 7 under. He was followed by 54-hole co-leaders Rumford and Chalmers and 6 under and 5 under, respectively. Adam Scott, the native Australian and Masters champion, rounded out the top five at 4 under after shooting even par on Sunday. Scott struggled early, making bogey and double bogey on holes four and five. he would go on to make three bogeys and a double on the day.

World No. 1 Rory McIlroy competed in the event and was in contention through two rounds, but a third-round 5-over 76 put him out of the race. He shot one over Sunday and finished T-15 at 2 over.
