Security guards quickly grabbed the protester and dragged him to the locker rooms as a surprised Nadal looked on. The unidentified man was one of several shirtless men who donned masks to protest France’s same-sex marriage law, which went into effect several weeks ago.
Two other protesters were escorted off the grounds after they unfurled a banner reading, “Help! France tramples on the rights of children!”
Nadal won the match, securing his eigth French Open win.
