I'm thankful to be able to team up with a company like USANA that cares about my well-being and I know we can do great things together.

I start laughing every time because the media talks to me like I'm finishing my career and I only have one year left and time is running out.

The fact is I still have quite a few good years in front of me. I still improve.

I'm the type of player I am.

It's very expensive to be a professional tennis player with all the travel and the flights and the hotels and everything.

I try to be myself and, of course, be a good role model. I don't really find it hard, but you think about what you do and that other people look up to you.

I do my best, and that's all I can do.
