As a tennis player, or any professional athlete, our career has a shelf life. I don't want to waste any opportunities, I don't want to look back on it when I'm 45 and think I could have done a lot more.

A lot of times when I'm confident and relaxed on the court, I'm going to be a pretty tough out. But when I'm not so confident and not so relaxed, I tense up and my balls fall short and everything. It just sort of unravels.

In the past, I've played where I only just rely on my serve.

I've played with Prince racquets my entire career.

Family's first, and that's what matters most. We realize that our love goes deeper than the tennis game.

I owe a lot to playing on the street. And what was even better than playing on the street was playing football with my friends in the local graveyard. It was fantastic. We forgot what the time was and didn't even go home for our meals.

First Take' is known for the hot sport debate, which we'll continue to have. But also, I think another important aspect of the show is having the big-time interviews and the big-time guests, and being in New York gives it that feel.

It's tough to be a 15- or 16-year-old athlete competing around the country. There's tension, there's media. I had no idea what I was getting into.
