The only one I feel pressure from is myself to go and give my all for every match and, obviously, I'm a competitor.

I like to be with my friends and my family, listen to music and read books. Things like that relax me.

To be the world No. 1 has always been a dream for me.

Golf can be tougher than tennis when things go wrong, because you can't explain things by saying that your opponent played better than you. It's a cruel sport in that way.

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

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.

There are a lot of things to my game I can still improve, but everyone can.
