I think what Nadal really does best is hitting passing shots. He can consistently pass anyone from either side even when he is way out of position on the full run. I don't think anyone can do that as well as he does in tennis history. His strategy is very simple. At the baseline he has the advantage by using his lefty forehand to hit heavy topspin to his opponent's backhand. If his opponent comes to the net he will get passed 8 out of 10 times. It is a no win situation (for his opponent) especially on clay.
