This trick shot by Roger Federer was most definitely real. He's even hit it before. The five-time U.S. Open champion was up at the net when his first-round opponent, 96th-ranked Brian Dabul of Argentina, lofted a lob. Federer spun around to sprint toward the baseline. A couple of steps before reaching the wall behind the court at Arthur Ashe Stadium, and with his back to the net, Federer swatted the ball between his legs. The shot landed in a corner beside Dabul, who raised his eyebrows and shrugged.
