There used to be a lot more politics in the Olympics, when the Soviet Bloc committed a lot of resources for propaganda purposes.

I knew I was the second-best tennis player in the state of Florida and No. 8 in the United States of America when I was 12 years old and I couldn't tell you what I was in baseball, but I liked my chances in tennis of getting a scholarship to college.

It's really easy to find your friends when you're playing away. You have a close-knit group with you and everyone else is cheering hard for their side. There's more satisfaction coming away with a road victory.

Sports for me is when a guy walks off the court, and you really can't tell whether he won or lost, when he carries himself with pride either way.

There is a lot of pressure on tennis players like other sports that are singular like you're not on a team. When all the pressure rides on your shoulders, it can be a lot different. Team sports you share those moments with the teammates. You share the pressures. You share the wins. You share the losses. You have a coach that can change the course of matches. But in tennis you're out there by yourself. There are no caddies. There are no coaches. You do it alone in the arena and I think that ups the ante a little bit.

Flying has opened up new horizons for tennis.

The first thing I would do is create one office that controlled all of pro tennis so you had one central voice that spoke for tennis. Central governance is something that's really held the sport back and will continue to do so.
