The shortstop is a perfectly conditioned athlete. You're running out on relays all the time. You're covering second base. On every pitch, you're moving.
Playing shortstop is 75 to 80 percent anticipation, knowing the hitter and the pitch being thrown.
As far as sleeping goes, you're up and ready to go at six in the morning. Spring training was always a combination of relaxing and working, and I missed that quite a bit. I missed being around the ball field. A baseball. A bat. The smell of the uniform, you might say. Talking baseball. Seeing opponents as well as the Cubs.
