I was reading the explaination that is decribed on the http://www.batspeed.com/tf09.html page and am have difficulty understanding the possible cause of this "uppercut swing" flaw. (Earlier vs. Later drop of the lower forearm?) My son has a muscle memory issue and has a tendancy to dip. I am now using a large mirror at my batting club so that he can see himself.I have been over emphasizing staying level through the rotation. I have seen numerous photos, to include my Batspeed DVD, where batters are lowering their shoulder.
> 1. Please explain the earlier drop of forearm theory.
> 2. At what point is dipping to far?
> 3. Is over emphasizing shoulder level correct?

For more data,download and view Griffey and Castilla clips from this site:

The angle needs to stay in the back elbow as it slots and assists in continuing to coil the body,then the angle stays in the elbow as the torso uncoils to drive the handpath bat,then only later,once this is underway does the angle come out of the back elbow approaching contact,moreso for outside location.

Another key question(see truism and fallacy you linked)

Can the back shoulder dip and the front shoulder come up without collapsing the back side ?

I think so IF the weight(center of gravity) gets forward and down first,then when the front shoulder comes up,the axis is stabilized as the front side firms up and coiling of the body is actually accentuated instead of the backside collapsing.Actually,this may be desirable.

You can see some of this (joint angles/path of body parts) in the clips.
