Wimbledon wasn't the only tennis tournament on over the weekend. At the Winnekta Challenger tournament in Illinois, Russian player, Alex Bogomolov walked off the court in a semi-final after a spectator appeared to call a shot out.
Bogomolov approached the chair umpire apparently telling him that he could no longer continue. He calmly packed away his equipment, rose from his chair, told the umpire to "go fuck yourself" and left the court.
