Instant replay! aka shotspot Federer has publicly made statements against the instant replay rule. If the USO does employ this new feature, Federer will lose his edge at bullying the linesmen, umpire, and in general, he'll lose more points than he would have gained when he's balls are called out.. This is why Federer has been so against the instant replay rule. Hewitt will simply say.. "Instant replay it mate!"... and Federer in his headband will have to replay the point of which he'll eventually lose! I predict federer out by semis.. anyone want a wager?
