Became the first Challenge Tour graduate to win a Major Championship in 2005 when he won the U.S. Open Championship after holding off the challenge of Tiger Woods at Pinehurst No.2. Was the first New Zealander to win a Major since Bob Charles in 1963, prompting wonderful celebrations in his homeland.

Followed that by becoming only the fourth player to win the U.S. Open and the World Match Play Championship in the same year.

Not surprisingly, was named 2005 European Tour Golfer of the Year and given Honorary Life Membership of The European Tour in recognition of his US Open triumph. Previously honoured in the Queen’s Birthday Honours List in 2001 where he received an Officer of the New Zealand Order of Merit Award for his services to golf.
