Many times people will peg genius as being to near to insanity. Some are called savants because they have a talent that holds the rest of the world awestruck. Nadal has this kind of talent in tennis. He burst onto the scene by defeating Roger Federer in a Grand Slam final when Nadal was just 19 years old. At the time Federer was considered by many to be unbeatable, but Rafael proved them all wrong. However, he has never been linked to autism and it seems that his focus is saved for the tennis court. And he remains one of the greats.
