I am watching Rafael Nadal's first-round match at the U.S. Open--his inaugural outing as the world's #1 player. It doesn't look like he is playing particularly well, I have to say. Bill Macatee made an interesting point, though: in May, Nadal was just a match away from dropping to #3 in the rankings. He has certainly put together an incredible summer of tennis since then. It would be a shame if fatigue catches up to Nadal such that he doesn't go deep into the second week of this year's Open. Obviously there would be tremendous interest in another Federer/Nadal showdown.
