Is there a penalty for F3 or F5 not having BOTH feet in fair territory when F1 delivers the pitch to the batter? FED and NCAA both specify that only one foot must be in fair territory but I can find no such clarification in OBR. I see in OBR Rule 4.03a where it is a balk if the catcher is not in the catchers box at the TOP. Does this penalty apply to a fielder for not being in fair territory also? And if it is not a balk, how do you handle the situation when the OC complains about it?
