Watch Rafael Nadal hit a ball straight into the press booth after his quarter final match with Diego Schwartzman. The Spaniard said: "I think I had stable character during all my life, all my career. That helps to be normally in stable -- I mean, mentally focused, mentally relaxed and mentally always ready to respect every opponent, to play every point, to play every game, to play every set and every match until the end, no? So that's one of the keys of the success.
But honestly, is not everything. I think my success is not only because of the spirit of fight. There is lot of things after this."
