When I committed to playing a little tennis in some exhibitions, it was the best thing for me. It got me in shape. It got me out of the house. It got me doing something I love to do.

Players aren't quite as intimidated by my name.

Retirement is a work in progress. I try to figure out my day, and what I know about myself is that I need structure.

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.

Winning is about taking your opponent's heart out and squeezing it until all the blood has come out, even the very last drop. There are no prizes for a funny loser.

I hate to lose, and I do whatever I can to win, and if it is ugly, it is ugly.

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