Question: In high school softball, if a substitute is not listed on the lineup card, is she allowed to enter the game?
Answer: Inaccurate lineup card is penalized with an initial warning to the head coach; sub is added to the card and allowed to play. For a subsequent lineup error, the head coach will be restricted to the bench but the subs may play. (SB-Rule 3, Sec. 1, Art. 3)
