Who came up with the "Squash Shot"? Earliest I can remember is the famous Federer forehand in the 2006 French Semis against Nalbandian. Even as recent as three years ago, I remember watching a match and the commentators made fun of Azarenka hitting a "granny shot." Now it seems every player has that wide forehand wrist hinge that is now an accepted defensive weapon. Did this shot exist before Federer?
