Day's reputation in Australia--he won the 2004 Queensland amateur and, as a 17-year-old, was runner-up in the 2005 Queensland PGA Championship--initially helped him receive five sponsors' exemptions on the PGA Tour. Day made the cut in four of those tour events, tying for 13th at the U.s. Bank Championship in July and tying for 11th at the Reno-Tahoe Open in august.
