Called strike

[Fastpitchnutz]

I should have stated that this is ASA, 2nd year 12s. When she throws it she is within the pitchers mound. If it was to hit the batter it would be on the back side as it tails to the batter. If she can throw it as a strike (per ASA) even if it hits the batter after going through the strike zone, why would it be called a ball?

Thanks,
