Nathan Andrew Green is an Australian professional golfer. Born in New South Wales' second-most-populous city, Newcastle, Nathan Green turned professional in 1998. During his early career, he played mostly on the PGA Tour of Australasia, and the Canadian Tour during the Australian winter. In 2000 he won the Queensland PGA Championship in Australia, and the Benefit Partners/NRCS Classic in Canada. Having failed to gain his PGA Tour card through the qualifying school, Green competed on the second tier Nationwide Tour in the United States in 2002, 2004 and 2005. He ended the 2005 season 18th on the money list, which enabled him to graduate directly to the PGA Tour for 2006. He finished 5th in his first event on the PGA Tour, and in his second, the Buick Invitational, he made his way into a playoff for the title against Tiger Woods and Jos� Mar�a Olaz�bal, but was eliminated at the first extra hole. He finished the year ranked inside the top 50 on the money list. Green's victory at the New Zealand Open in December 2006 raised him into the top 100 of the Official World Golf Ranking for the first time.
