At a certain point in the [golf] tournament, it becomes a match play event and becomes a match play event against who is on the leaderboard, so you have to know who is there to do what you're going to try to do.

There is no room in your mind for negative thoughts.

I don't believe in philosophies. I believe in fundamentals.

You can win tournaments when you're mechanical, but golf is a game of emotion and adjustment. If you're not aware of what's happening to your mind and your body when you're playing, you'll never be able to be the very best you can be.

I've had a lot of majors where I didn't play well until the last round. Keep yourself in contention; that's the name of the game. I usually ended up shooting a good round and all of a sudden, somehow, I won.

I never hit a shot, not even in practice, without having a very sharp, in-focus picture of it in my head.

But if I played well and prepared myself properly, then all I had to do was control myself and put myself in a position to win.
