US Open: Exit Nadal.

The second player in the world, Rafael Nadal didn't look at his best yesterday as he was defeated in four sets by David Ferrer (15). The final score: 6-7 (3-7), 6-4, 7-6 (7-4) and 6-2. A match that ended in the wee hours of the night. So Ferrer surprizingly qualifies himself for the quarterfinals with this upset victory.

In another very disputed match yesterday, Novak Djokovic (3) also qualfied himself for the quarterfinals as he defeated Juan Monaco (23) by 7-5, 7-6 (7-2), 6-7 (6-8) and 6-1.
