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.

I'm definitely not at my best. Honestly, I'm under 50 percent. But I've won stuff under 50 percent before.

I like to wear classic silhouettes and add a punch to it. I'll wear a high-waist legging and a super-crop top or a see-through top with a nice bra underneath. And I just always try to mix it up with heels or something.

You can't underestimate anyone.

I'm an athlete and I'm black, and a lot of black athletes go broke. I do not want to become a statistic, so maybe I overcompensate. But I'm paranoid. Oprah told me a long time ago, 'You sign every check. Never let anyone sign any checks.'

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 never thought about leaving a tennis legacy. I always thought about leaving a legacy of fulfillment, living out your dreams, and giving back.
