The USGA says the caddie for Sei Young Kim was removed from the U.S. Women's Open for taking photos of internal notes on the course setup.
Paul Fusco will not be allowed to caddie this week at Lancaster Country Club. The Women's Open starts Thursday.
A USGA spokesman says Fusco was found to have taken pictures of a USGA document. Such matters as hole locations are not available to players until the day of the tournament.
Kim is a top LPGA Tour rookie and was runner-up in the last major. She will have to find another caddie for the week.
Fusco previously has worked for Paul Casey and Steve Flesch on the PGA Tour, and for Na Yeon Choi on the LPGA Tour.
