Pitching Inside | Talk Pitching | TopVelocity Baseball Forum

I am doing research on pitching inside. Mainly looking for the intent of pitching inside to move a hitter's feet, his hips, and his hands.

What tendencies of a hitter provoke the need to move any of these 3 areas on the hitter and how it sets up pitches throughout the at bat.
I heard Orel Hershiser break this down masterfully once during a game he announced a few years ago, just can't recall the exact words.

Can't seem to find this info anywhere.

Thanks
