People thought it was asinine for me to change my swing after I won the Masters by 12 shots. ... Why would you want to change that? Well, I thought I could become better. If I play my best, I'm pretty tough to beat. I'd like to play my best more frequently, and that's the whole idea. That's why you make changes. I thought I could become more consistent.

Most players I play with, I don't look at their swing when they're over the ball or anything like that.

I've been going to chiropractor for as long as I can remember. It's as important to my training as practicing my swing.

I started changing my swing in late 1999.

My dad was a big believer of having a golf club that fit me. Always have a golf club that fits you, so you don't have to make any swing compensations for that particular golf club.
