There's just nothing like playing on Arthur Ashe Stadium. It's truly amazing.

I never give up. Doesn't matter what the score is.

My dad has always been my coach. And I've spent so much time with him. So he's one of my best friends. And I can talk to him about everything.

I have a really wide range of interests and I've still got time to work out my exact direction.

I actually had a small kangaroo - and I'm not kidding this time. I was holding a small kangaroo, baby kangaroo ... it was very nice to me this time. Do you know what it did afterward? I gave it some milk, and it just spit it all over me. I was like, Is this a thank-you for just being nice and petting the kangaroo? I got milk all over myself. I guess I deserved that from the story last year.

My parents just always taught me to be reasonable.

I don't know, I always get the question 'how do you feel after the game today?' and, of course, if you're winning you feel great and if you lose you don't feel good. I think that's a pretty obvious question.
