Early batspeed is not only quick acceleration, BUT being able to start this acceleration well behind the batter so as to provide maximum read time and cover the strike zone well.

Tom. No offense, but I just could not get into that mechanical view. Nevertheless I appreciate you taking time out to involve yourself in the discussion. (But I have seen a similar video with Pete Rose and Johnny Bench.)

NOTE. I am not disagreeing with Jack's overall concepts. I just do not believe Sosa is applying them.

It is unfortunate that we cannot get a better side view of Sosa. Unfortunately it looks like another unresolved discussion.
