Guys, one must also not forget Fedex's mental strength. Against almost anyone except Nadal or Djoko (and perhaps even against these two), Fedex has an inherent belief that he can defeat players. Against Roddick, the match was very tight, but Fedex NEVER had any doubts about winning the TIEBREAKS even, forget the set. He always knows that he can find that extra gear. Especially against Roddick who came with a game-plan circa??-1999 ?Roddick should know by even if he uses a power-based approach, that will quickly break down in 1 or 2 sets, and Roddick is NOT a good defensive player at all (by Coach Connor's own admission).So Fedex waited just for the right moment and seized it, like the 5-4 point in the 2nd set tiebreak. He knew he had 2 serves of his own, so he took 5-4 and held his serve to take the tiebreak 7-4. And the rest of the match for Roddick, being 2 sets to love down was like facing a death sentence, in the words of none other than Andre Agassi, who was the expert commentator on USA network.
