As long as I feel like I can win majors and contend, I'll continue to play.

Anything can happen out there on any court.

I made it look so easy on court all those years. No one realized how hard I had to work. No one realized how much I had to put into it. They underestimated my intensity.

In tennis, you can make a couple of mistakes and still win. Not in golf.

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.

Golfers are forever working on mechanics. My tennis swing hasn't changed in 10 years.

I'm not going to give in to the critics. I'm going to stop on my own terms, not on when someone else thinks I should.
