It's awesome to have the crowd on your side.

In a tiebreaker, you generally have a lot of adrenaline running through. It's all about just holding your serve, trying to hold two serves at a time, trying to stay ahead in the tiebreaker, constantly put pressure on my opponent.

I know where I'm ranked, but I don't look at it that much, I don't study it that much. You really can't look at it that way, you've got to try to win as many matches as you can, and it's cliche, but you've got to take it one at a time.

I'd love to have Trump come watch me. That would be awesome.

The best thing about being 6'9'' is that it helps with my tennis game, especially with my serve.

My marriage and my career are my two top priorities.

My favorite tournament is the U.S. Open because the atmosphere is great.

You cannot just play tournament after tournament like maybe I did when I was 23, 24 years old.

I had no idea I was going to be this tall. Had I known that, I honestly would have stuck to basketball.

Prior to our daughter being born, I think getting married is another big step. That definitely settles things down personally.

I was always a late bloomer.

In any match, making a lot of first serves is very important, especially for me.

Everyone works so hard on their game and on their body. Most of the time, it comes down to who is more relaxed mentally; on the court while playing and off the court.

I'm not really focused on my ranking.

I try to bring a lot of water on the plane with me and eat a really good meal.

There's a lot of times I'll just play too passive and since I'm not going to play defense as well as most guys can, I can't get away with passive play.

For the most part I consider myself a mentally strong player.

I didn't know I could even be a professional tennis player, honestly. All this is actually very, very unexpected.

My coaches, trainer and agency have all helped make me the player and the business that I am today.

Everyone wants to start the year off well.

You can't not love it here in Paris. It's amazing.

It is very hard to stay up there in the Top 20.

I've always stayed hungry.

When you're out on the court, you're fighting against yourself and it can be tough.

I grew up in a nice neighborhood in Greensboro, N.C., which is not too big, but definitely not a small town.

I always ask for the exit row when flying. Airlines are pretty accommodating and most of the time I'll get it.

I think college tennis makes you tough.

I was playing 60, 70 matches a year in college. In the pros, unless you're winning, you're not playing that many.

My confidence sort of comes and goes very quickly.

I stopped eating airplane food; it's not that good.

I was always so big, it took me a long time to grow into my body.

I almost went with basketball over tennis.

I can't beat guys consistently playing like I'm 5-foot-10.

People seem to think when you lose a match it's because you are not working hard.

Playing four years of college, when you're playing for someone other than yourself, I think it makes it a lot more fun.

That would be a huge honor, if I ever were to become the No. 1 American. It's something that I've always wanted to, you know, achieve that. For me, if were to happen, it'd be great. I'd try to hold onto that spot as long as possible, but I know there'd be a lot of people nipping at my heels to try to get to that No. 1 spot.

When I travel to a grand slam, I need to look for a place to stay for me, my family and my team.

For me, I relish playing tournaments in America.

That's the most fulfilling thing I've experienced ever, being a father.

As anyone who is a father or mother out there can tell you, it's pretty amazing.

Practicing hard doesn't guarantee you anything.

Being able to travel with family and friends so they can cheer me on as I play is something it's hard to put a price on; my point is simply that for all of this, there is indeed a price.

People often come up and tell me how much money I make in a year, which is funny because I don't think it's something I've ever said to someone.

The way I see it, the prize money is a reflection of my on-court performance, but the sponsorships are something more personal, connected more to people and fans, and to my values.

The mental part of the game, being able to free up on the tennis court, is much easier said than done.

At 19, I didn't have a hair on my face. When I was 20, I looked 14.

Tennis is not really a traditional Olympic sport.

The coaches that I have have done an incredible job with me, obviously the stuff we work on on the court.

I haven't really worked with, like, a mental coach or anything.

Yeah, certainly you want to try to save your energy at a Grand Slam.
