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.

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

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.

When you're picking a basketball team, you'll take the brother over the guy with the yarmulke. Why? Because you're playing the odds.

What I'd most highlight about Leo Messi is his huge sense of responsibility for the team. It shows in every game in every competition.

Anyone who loves football can also be involved in music; the two aren't mutually exclusive.

My time off is usually spent working out and getting better at football. When I come home and spend time with my little brother, we're out on the football field. We're working out or playing Madden. We're spending time with each other, but our quality time is football.
