Every player gets frustrated on the court. Accordingly, every player seems to have developed his or her own signature move to deal with said frustration. Andy Murray starts yanking things. Maria Sharapova looks forlorn. Andy Roddick and retired former world No. 1 Marat Safin, among others, destroy rackets. Serena Williams, well, I'm going to leave that alone.
