It's an extremely disappointing day. Frankly, I thought Nadal was the favorite going into Wimbledon given how well he was playing and that Djokovic hasn't been on the same level he was last year.
If Federer wins, he will not only add a 17th major title to his resume, but he will also become #1 in the world again. That means he will tie and then pass Pete Sampras for the most weeks at #1. Currently, Sampras is at 286 with Federer at 285.
The draw is now wide open. All of a sudden, Andy Murray has a legitimate path to the championship. Tsonga has been playing exceptional tennis and had been in Nadal's quarter. Del Potro and Raonic have the ability to hit anybody off the court. Federer now has a chance whereas he really didn't before because he'd have to have gone through Nadal, who owns him. Maybe Rosol will win it all...just kidding, I think.
