After I went through two years of not winning an event, what kept me going was winning one more major. Once I won that last U.S. Open, I spent the next six months trying to figure out what was next. Slowly my passion for the sport just vanished. I had nothing left to prove.

In tennis, you can make a couple of mistakes and still win. Not in golf. I played three rounds in that Tahoe event, and I was drained. Mentally, not physically.

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

The difference of great players is at a certain point in a match they raise their level of play and maintain it. Lesser players play great for a set, but then less.

Where I fall down is my short game. I don't practice enough, and when I have to take a half swing from 50 yards out, that's trouble.

I don't think it really matters, who plays first. Whatever they do, they do.

When I committed to playing a little tennis in some exhibitions, it was the best thing for me. It got me in shape. It got me out of the house. It got me doing something I love to do.
