The best sport ever -
So - why is it good?
You can play it in singles or doubles so it would be even better to play tennis with your friends in a 2v2 match!
The best player in the world!
Rafael's worst game was in 2005 when he played against Novak Djokovic. He played 5 sets of games and lost every single one of them. Even though he lost he was not disappointed because he broke a world record of a 5 hour match.
