We do more ready-to-wear and ath-leisure, things you would wear everyday. I never close my mind to anything and eventually want to branch out. But for now, tennis is still number one for me.

My fridge is really just vegan: coconut water, Gatorade (my favorite!), cucumbers, mint, kale, vegetables, ginger, and wheat grass.

If I'm not playing well, I do get down on myself because I am a perfectionist. [So I need] someone who believes in me more than I believe in me, someone willing to work as hard as I work. I don't understand what no means or what failure means; I only understand what yes means and try again means.

I've been involved with Berlei for almost my whole career. I actually discovered them well over 10 years ago, probably 2002 at least. My mom introduced me. She said, "Listen, you should try these bras." And I was like, "Really?" So I tried it and since then I've never worn another bra.

Luck has nothing to do with it, because I have spent many, many hours, countless hours, on the court working for my one moment in time, not knowing when it would come.

It's so great to have that opportunity with so many young American players coming up now. It's just so exciting. We have to root for the home country.

I'm a big supporter of this product for women. And [my relationship with the brand Berlei] was so organic. I would go to the store and buy 40 or 50 bras every year because I could only get them in Australia at the time. And then eventually they heard that I would come and take all the stock.
