I used to, like, hit for a half hour and then go eat Cheetos the rest of the day, come out and drill forehands. Now I'm really trying to make it happen, being professional, really going for it, and I miss my Cheetos.

It's pretty high up there on the list. Being able to return a serve at that speed is one of the biggest things that separates the professionals from the recreational players.

Is that the longest fifth set ever? It was? So, no, I've never played one longer than that!

I'm not the savior of men's tennis in America. I'm just a kid trying to win a few matches.

I had a very detailed retirement plan, and I feel like I've met every aspect of it: a lot of golf, a lot of carbs, a lot of fried food, and some booze, occasionally - I've been completely committed... The results have shown.

I don't know that I've ever been someone who's interested in existing on tour. I have a lot of interests and a lot of other things that excite me.

I'm just glad to see that Pete (Sampras) shut everyone up last year. That was satisfying. You can't bag on guys like Pete or Tiger (Woods) or Michael Jordan. They can play as long as they want, they can do whatever they want. Nobody should be able to tell them differently.
