I used to hear a lot that all I could do was hit a serve, I couldn't volley, I can't hit a backhand, I don't return well, and then people would turn round and tell me I'm underachieving.

I think I have a lot of room for improvement. My serve is okay, but I need to work on a lot of things: return, transition game, backhand.

When you come off something really disappointing, you want to come back and kind of regroup and get involved in something positive right away.

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

I used to go to the US Open on my birthdays and sit in the nosebleeds.

I always said if I had to pick one Grand Slam to win, it would be the U.S. Open.

Call me All-American, but I love Ham and Cheese sandwiches. And not just any old ham and cheese sandwich... My mother's is the best. I've tried many times to make these sandwiches on my own, but it's never the same.
