Roger Federer just won tennis with this shot in Brisbane, Australia, on January 2. In a doubles game with partner Nicholas Mahu he beat the pair of Dimitrov/Chardy at the Brisbane Invitational, but everybody will be talking about this shot rather than the match.
It may have been a mishit, but it's pretty amazing nonetheless. The forehand shot spins high into the air, bounces on his opponents side of the court (winning the point) and then bounces back on to Federer's side.
Did he mean to do it? You decide!
