I let my racket do the talking. That's what I am all about, really. I just go out and win tennis matches.

I still feel like my game is very dangerous. I always will have my serve.

In tennis, you can make a couple of mistakes and still win. Not in golf. I played three rounds in that Tahoe event, and I was drained. Mentally, not physically.

There is no doubt about how hard it is to stay on top in any sport, but to do it in an individual sport for the majority of your career, it is not easy.

Tennis is seen all around the world; if I am home or anywhere in the country, United States, people will stare.

I may be a step slower than I was before reaching 30, but I'm doing all the right things. I guess there are some guys who would take it easy in the latter part of their careers, but I'm stepping it up.

Golfers are forever working on mechanics. My tennis swing hasn't changed in 10 years.
