I wonder if this could be the beginning of a changing of the guard in Men's tennis. Murray beat Djokovic and Federer relatively easily. Del Potro played Federer evenly and also beat Djokovic (it should be noted grass is Del Potro's worst surface by far).
Can they carry this momentum to the regular tour? It'll be interesting to watch.
By the way, Usain Bolt might be the most freakish athlete I've ever seen. Happy to see him win. I think, particularly in America, his accomplishments were glossed over in Beijing thanks to Phelps. The dude is every bit as dominant.
Also, kudos to Phelps, who is still the best swimmer in the world. Ryan Lochte and his "my time" prediction... not so much.
