I'm not worried about the weekend, I'm worried about Saturday.

Once the US Open is over in the States, mainstream America doesn't really follow tennis, unless you are a true tennis fan.

It's one-on-one out there, man. There ain't no hiding. I can't pass the ball.

There is no doubt about how hard it is to stay on top in any sport, but to do it in an individual sport for the majority of your career, it is not easy.

My goal one day is to be in the same sentence as Rod Laver and Ken Rosewall.

Most of the time after the US Open, it is kind of like you are trying to finish strong. But to do it five years and maybe six is something that has never been done before, so it is a huge challenge.

When you struggle winning matches all year and you don't really get into a groove or rhythm, you just can't expect to just come in here and have it click.
