Thanks for good write up. It's not really to far off from where my views are. Question: when you said previously that the hands are directing to a location, when does that occur? Is it in conjunction with the body or is it at a later time?
That will depend on the hitter's timing and the location of the pitch. As the stretch is built, one of the muscles that becomes stretched is the serratus anterior. That muscle along with others will be involved in delivering the barrel to the ball via the "hands to the ball" cue. Again, I wouldn't take the cue literally... The hitter is connected (hands near shoulders in space) throughout the first 1/2 of the clip (roughly...). Then his hands move 'out from' his body to a location where the barrel can contact the ball.
This process is going to vary based on pitch location. In each of the Miggy clips below, his hands are moving 'out from' or away from his body in a direction towards the incoming ball.
Some view this as a two step process. First you do this and then you do that. I don't see it that way. I see it as one fluid movement that will have some variations based on timing and pitch location. Some will also say that direction is determined much earlier and that the rest of the system is essentially on auto-pilot. I'm not really a fan of that thought process either. In my opinion the answer lies between those two extremes.
