I'm uncomfortable with it. When I thought of playing baseball, I never thought of that. It was never important to me. I am a little tired of it, and I've had enough.
In '05, '06, '07 and '08, I wasn't throwing any changeups at all. Maybe two or three per game. In '09, I started playing with the grip, started throwing it in the bullpen and playing catch. It came out really good.
