I think you have to state that you saw a swing. "Yes! She did!" or "That's a swing."

This lets people (especially coaches) know that while the ball was out of the strike zone, you have a swing, and therefore a strike.

Simply just calling a strike will get you in trouble if a pitch is up around the batter's eyes. If you don't somehow acknowledge it was a swing, coaches will be on you for your crappy strike zone.
