(straight and inline forward) during launch, what is causing the bat-head to
accelerate in an arc back toward the catcher?

there is a difference of 2-3 ft in the contact point. I disagree, as I have 4
extremely good clips of Rodriguez pulling the ball, and he is making contact
just a little in front of his lead foot. I have over a 100 clips of Bonds, and
actually can find some where he is making a good swing and pulling the ball
where he is up to 8-10" in front of his lead foot. Bonds, in the past 3-4 years
has moved farther from the plate......he was at one time about 3" from the plate
and now is about 8-9" off. A-Rod is about 13-15" off the plate. Bonds made the
move, because at the time, his only weakness was a little up and on the
inside corner.....he now has that handled.
> > I feel that A-Rod is a glider who is a rotational hitter. We can put a bunch
of rules out that say this and that has to be done or you are not rotational, but
that is just arguing for the sake of arguing. For someone to say that A-Rod
would be better if he changed is just a wild guess....he is the best hitting
shortstop of all time, and if he stays healthy, his stats will prove it. Jack,
doesn't the bat head accelerate back towards the catcher on all swings?
Where else would the bathead go? A-Rod also will many times make contact
with his back foot off the ground too, which means that he has transfered
weight over to the front side and was not striding to a balanced position and
then rotating. He also has a flexed lead leg at contact.

> I'm guessing that he strides to a balanced position and the shear speed of
his bat pulls his back foot up...bat comes around and the foot is back down. he
doesn't fly forward.... think? Rich

Rich-

I think some of these are reactive forces,more prominant when the back foot
bears less weight.This is analagous to the situation in pitching,but less
complex.See in the case of pitching:
