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.
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.
People wrote me off, but I believed in myself. I got the confidence back, and it grew and grew. I won my first major and my last at the place that changed my life.
All I cared about in tennis was winning.
I could be a jerk and get a lot more publicity, but that's not who I am.
