When I first came up, the bullpen was pretty much where they put the guys who couldn't start.

But through experience I learned to control my body and locate the ball.

My career spanned the era when relievers started to become more important

That first year in Chicago was one of the most memorable in my career. Getting traded rejuvenated me, and I had something to prove. I wanted to show them what I could do

You aren't going to stick around long with just two pitches

Later, I could take something off my slider and I could make my fastball sink, so I really had four pitches.

I also think that I had great mechanics.
