Will I have to explain to my daughter that her brother is gonna make more money doing the exact same job because he's a man? If they both played sports since they were three years old, they both worked just as hard, but because he's a boy, they're gonna give him more money? Like, how am I gonna explain that to her? In tennis we've had great pioneers that paved the way - including Venus [Williams], who fought so hard for Wimbledon to pay women the same prize money they pay men, and Billie Jean King, who is one of the main reasons Title IX exists.

I want it to be more natural. Right now it feels really forced. Seems like I've never done a curtsy before, which may be true. But I'm looking forward to nailing it.

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

I never close my mind to anything and eventually want to branch out. But for now, tennis is still number one for me.

We're sisters, we're roommates, we're all that.

I am lucky that whatever fear I have inside me, my desire to win is always stronger.

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