WELLINGTON, May 2 (Reuters) - New Zealander Michael Campbell, who famously held off Tiger Woods to win the 2005 U.S. Open, has decided to retire from professional golf at the age of 46 because he has lost the motivation to play.
Campbell followed his major victory with a tie for fifth at the British Open and a tie for sixth at the PGA Championship in the same year.
Campbell won 15 tournaments over his career, most of which was spent on the European Tour, but his last title came when he won the World Match Play Championship at Wentworth a few months after his Pinehurst triumph.
