It's a great win for Nalbandian (particularly coming off the heels of his title in Washington), but I now have serious questions about his fitness once again. Just as in years past, Nalbandian has the shots and ability to hang with anybody, but his level of play seems to severely drop as the match lengthens. I am now convinced that he is not a contender for the USO, as there is no way that he could off multiple best of five set match wins against the top players in his current shape. It's a shame too, as I am a tremendous fan of Nalbandian's clean ball striking.
We should be appreciative of Federer though, because we will never see anything like him again. The fact he can still compete for slams ever after the erosion of his physical skills is really a greater testament to the natural talent he has than the period of time when he was dominating the tour.
