In the middle of Roger Federer's exhibition match with Grigor Dimitrov at the BNP Paribas Showdown in New York, a kid in the crowd challenged Roger Federer and stepped in for Dimitrov for a point. The kid proceeded to work Federer, using both his forehand and backhand to draw him into the net for the dagger. As soon as Fed got to the net, bam, a perfectly placed lob shot that he could only watch and hope went long. It didn't and the point went to the Kid/Dimitrov.It's just an exhibition, but Federer does look a little salty when that ball drops in.h/t The Cauldron[ESPN]
