Just like many great players, Roger Federer has a switch which he can turn on to go that extra inch to get back in a game or to turn it up when needed.

I watched a little bit of his semifinal match against Nalbandian and realized that he was listless, almost disinterested in the first set which he lost and then went down 0-3 in the second. Then, all of a sudden, he flipped that switch and started making unbelievable shots, much to David’s dismay.

He convincingly won the second set and from the scores I see that he won the match when Nalbandian had to default because of some injury.

But it was amazing to see how quickly Federer went from a pathetic display of tennis to a champion’s display. Now that Nadal has crushed his Ljubicic and reached the finals, it will be damn interesting to see how the finals play out.
