I enjoy hitting tennis balls. I haven't lost any of the innocent parts of tennis. I just do it in front of less people..

At one point in your life, you'll have the thing you want or the reasons why you don't..

I'm not going to go run and hide because I'm catching some heat. I'm not going to stay at home and pout..

I don't know that I'll ever be the guy who needs to go to a tournament to be seen and to spectate. I feel like I can accomplish spectating from home..

I don't want to live and die with every point that's being played out there now. I'm going to let my coach live and die with every point..

I've been good about keeping my nose to the grindstone..

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

In the States, tennis is sixth or seventh on the totem pole as far as sports go..

I've become better at the net. I've got a 135 mph serve so I'd be stupid not to follow that in. Overall I'm a better player than I was last year..

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..

There's no doubt there are issues with clay. Our issues have issues that are issues right now. That's not a secret..

I'm gonna have to start winning some of the matches to call it a rivalry!.

I still don't believe I won the U.S. Open. It's so far-fetched for me..

I don't think I'm one of those guys who won't pick up a racket for three years...I love hitting tennis balls..

Stay in school kids or you'll end up being an umpire..

Why would I get a wild card into an American tournament, (as the) top-ranked American? Why would that happen? That makes too much sense. Maybe I shou….

Umpiring, the only job in the world where you can screw up on a daily basis and still have one!.

I don't really rate press conferences. It's not as though I leave the room fist-pumping my way down the corridor after a good one..

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

I got to play in a crowd, play in Wimbledon finals, be the guy on a Davis Cup team for a while. Those are opportunities not a lot of people get..

The only pressure I feel is what I put on myself..
