> It's the bat because something has to stop it. Try this:
> Take and axe and swing it like you are felling a tree but don't hit a tree. There are two ways to stop the axe. One is to keep rotating in the arc in a 360 as you try to slow it down. Since hitters look silly and can't run to 1st base if they are spinning in a circle, they let the bat go into a large arc, almost forward, after contact. This will pull the batter forward off their back foot. Weight has shifted but it was the head of the bat's weight, not the hitter's weight.


If this was the case the foot would come off the ground after contact but in real life it comes off the ground before contact so it could not be the bat and extension. The back foot coming off the ground can be caused by a few factors and in come instances good and others bad. If the back foot is off the ground caused by lower body mechanics they are usually good and if caused by upper body mechancis then they are always bad.
