Just looking back on all of Fed's many Grand Slam wins, there's only been one person to take Federer to 5 sets in a Grand Slam Final, and that was Nadal. All other competitors (Agassi, Gonzalez, Baghdatis, Roddick, Soderling, Safin, Djokovic, Murray, Hewitt) have tried to put up fights, but either lost in straight sets or only 4 sets. It's like Fed turns up the gas in the final, it's kinda scary to watch how agressive he plays in finals and hammers through them. And if they do make it to 4 sets there is at least one set Fed wins where they only get 2 games off of him (6-2 or 6-1 or even 6-0 set). Nadal has been exempt from that except at the Wimbledon 2006 final. Other than that he's at least taken Fed to 5 sets every time or even withstood the assault and beaten Fed. That's crazy to think about. Hoping for a speedy recovery for Nadal's knee. And congratulations to Federer.
