Michael Campbell will not be in the field next month when the U.S. Open returns to Pinehurst No. 2, site of his 2005 major triumph.
Campbell announced in a blog post that he will be stepping away from competition after recently separating from his wife, Julie.
"As I do not feel that I am either fully physically or mentally ready to play tournament golf at the highest level, after much deliberation, I have decided not to play in the BMW PGA Championship, the U.S. Open or the events in between," he wrote. "I want to get back to my best and I believe this is the best strategy to achieve this."
Campbell was a surprise winner at Pinehurst nine years ago, when he shot a final-round 69 to erase a four-shot deficit and finish two shots ahead of Tiger Woods. He continued to play well throughout the 2005 season and added a win at the HSBC World Match Play Championship that September, but has not won since. The Kiwi has made the cut only once in eight U.S. Open appearances since Pinehurst, tying for 58th at Oakmont in 2007.
Currently No. 520 in the world rankings, Campbell has not played since missing the cut at the Abu Dhabi HSBC Golf Championship in January. In his update, he cites problems with a "tendon in my left ankle" that sidelined him 2-3 months, but says he is now back to playing 18 holes.
