I think I would have viewed it as the batter stepping out of the box caused the pitcher to deliver an illegal pitch and thus called time/no pitch as soon as it became illegal.

But can you give a NFHS (Fed) ruling that would have allowed you to do this?
I haven't got my rule book handy, its in the office but I am pretty sure I got it right.

I need some rule references
