throwing bat at ball

[scyguy]

we have two separate rulings whether his foot is inside or outside box when contact is made. My confusion is whether or not leaving the hands to CREATE the contact is the same as having bat in your hands when contact is made.

For example,
RH Batter squares to bunt, right foot is on plate or out of box. Pitch is outside, he tosses his bat at the ball and makes contact. Ruling? It would seem to me that the batter is out for making contact with the ball while his foot is on the plate.
