The unannounced player will not have officially entered the offensive lineup and is therefore still available.
    1. In case of injury, if this will bring you below 9 players and you have already made substitutions, a player who was substituted is able to re-enter the game. If you are batting 10, and a player is injured, you have to drop down to 9 players. No out is call on the 10th batter.
