Hi guys, I am trying to visualize "scap loading" and "top hand torque". What I see today is that too many young players have what I call a dead start approach to hitting. The hands are still and then IMO it is hard to create any kind of loading. Oldtimers started with a hitch that had their hands going down, back and up, where they could then feel their bicep tighten,and in the words of some fine old hitters, "get your top hand in a position to punch" which helps create scap loading and THT, but the player does not have to think about it or try to accomplish scap or THT, it will just happen if you load (hitch) the bat properly.
