“The grass is very specific. I think we did a great decision that I played two tournaments before Wimbledon so I get few more matches to feel better on the grass.”
“I'm nearing 30, I really got to enjoy the time that I have. Obviously tennis is very important to me, but I have a life outside of that.”
“Oh, wait, wait. Can I practice here whenever I want? Is that one of the perks? Okay. Got to lock in.”
“Oh my gosh, I was nervous. I was very nervous. As you said, she's unbelievable. We've played so many times... you can't lose that focus. You have to still keep going and play every point.”
