The woman, whose name was not immediately available, approached Furyk near the green with the roses before being apprehended, a USGA official said. She had an advertisement for a Web site printed on her front and back.
''I was definitely caught off guard,'' Furyk said. ''I turned around and she was already up on top of me. I just wanted to back off from the situation and get back to playing golf.''
The woman was being held by local police, and was expected to be charged with disorderly conduct.
Furyk shot a 2-over 72 Sunday to win his first major championship.
