There are several recent threads on Fed's FH with analysis. I would like to focus on a specific point. When Fed hits his whiplike FH his swingplane is essentially parallel to the court, Clearly his face is closed as he begins the forward swing; nearly parallel to the court too. He finishes wrapped around his body BELOW the shoulder. I think he suppinates at or thru contact and then to release tension, pronates to the finish. Do you think he pronates before or after contact ??
