Ugly tennis... And Djokovic's game is completely sterotyped. He also has a hard time finishing the points.
Nadal is moving well, defending in squash shots, etc.
Actually, he was playing excellent in the first few games, with good length, pace, and agressivity, but then started to play more passively, with high balls...His shots became a bit shorter by the end of the first set, but Djokovic was not even able to take advantage of this. In fact, he looks a bit scared to hit some shots sometimes, and is missing some easy ones.
Edit: nice matchpoint, it reflects the match: Djokovic self-destructing.
He looked frustrated out there. Maybe he was too sure of himself, hence couldn't bear the fact that Nadal "resisted" him...very strange, he looked like 2 years ago.
