What should occur if the defense appeals an improper batting order?

If the defense appeals an improper batting order, the proper action is to allow the correct batter to come to the plate. In this case, B4 can take the place of B5. This resolves the situation by ensuring that the batting order is corrected without penalizing the team improperly.

The rationale behind this is that when an appeal is made regarding a batting order infraction, it is typically to rectify the situation rather than impose severe penalties like voiding actions or losing baserunners. Allowing B4 to replace B5 maintains the continuity of the game and honors the fundamental rules regarding batting order while addressing the mistake. This approach ensures that the game proceeds fairly and according to the established rules governing the order of batters, thus emphasizing the importance of having proper adherence to the lineup during play.
