looks good for any rules. I especially try to do the last sentence, although I usually call the out on any caught third strike or "1st occupied" out.

NCAA says to NOT routinely call the "out" on caught third strike; the contrast in not calling it on a drop is considered tipping the offense to the play. That's why they suggest you only call it when they appear confused.
