Midway through Roger Federer's championship match at the French Open on Sunday, a most bizarre event occurred: a spectator waving a flag climbed through the photographer's pit and onto Federer's side of the court.
Federer backed away toward the backstop, but the fan caught up with him and tried to put a hat on Federer's head. Security personnel seemed slow to react before chasing the man to the other side of the court, and he was tackled, then carried out.
There was silence from the stunned crowd, then the familiar chant of "Ro-ger! Ro-ger!" when the bizarre episode ended. Federer readjusted his headband, Soderling gave him a thumbs-up sign and play resumed.
