"I contend that tennis is the toughest sport in the world. It is emotional by its very nature, and it's the only sport that demands so many different types of physical and mental skill sets. And it all takes place while you stand alone in a gladiatorial ring thinly disguised as a simple tennis court. But there is nothing simple or serene about it. Competitive tennis is a battle!"
