Mickelson discloses at PGA he has form of arthritis that sent him to Mayo Clinic

Prognosis good after Lefty reveals health issue

SHEBOYGAN, Wis. — Phil Mickelson is being treated for a form of arthritis that surfaced just before the U.S. Open and left him in so much pain he couldn’t walk.

Mickelson, who could take over the world No. 1 ranking for the first time in his career at the PGA Championship this week, disclosed the condition Tuesday.

He says he went to the Mayo Clinic in Rochester, Minn., after the British Open, and is on medication that brings the illness under control. There shouldn’t be “any” issues long term, Mickelson said, and he is back to his normal practice schedule.

The arthritis is the latest health scare for Mickelson, whose wife and mother are battling breast cancer.
