Roger Federer hits his signature move, the SABR, on a 132 MPH serve. Amazing!!!! Federer last hit this shot at the Match for Africa 4 where he defeated the American Jack Sock. That event raised million of dollars. Federer is currently competing at the Laver Cup with legends like Novak Djokovic or great players such as Nick Kyrgios. We will see how the Swiss will do in this event, it will definitely be a show.
