The reason I didn't take the baseball route is because they don't have rankings for baseball players.

Us going out there and performing our best. That's how I define success. I'm not going to define it for us by the wins and the losses as much as by the effort and how we handle ourselves.

Many books have been written about what the X-factor is, what separates people who win big matches versus those who struggle. Some of it's innate, but there's a piece of it that's learned, embracing those moments.

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.

I will do everything in my power to make sure people are aware that our team is out there fighting the good fight for the tennis fans of the United States.

I think all of us are shaped by the choices we make.

When I turned professional, what I was really aiming for was to be in the top 100, try to hold the top 100 for ten years, and just be in the show, and have a nice career. It's more than I could have ever hoped for. I worked awfully hard for it, but there are other people who worked just as hard and didn't get the breaks. I recognized that I've been lucky and being able to live this life that I wanted since a young age. I really went after it with everything that I have and somehow it worked out.
