What happens if the plate umpire forgets to notify of a lineup change?

If the plate umpire forgets to notify about a lineup change, the lineup change is considered unofficial. In softball, the official lineup serves as an essential part of the game, as it defines who the players are and their positions throughout the match. When a team makes a change to the lineup, it is vital for both the umpire and the opposing team to be aware of these changes to ensure fair play and accurate record-keeping.

An unofficial lineup change can lead to confusion during the game, affecting the strategy and play of both teams. If the change is not officially acknowledged by the umpire, the game may continue without the new players being recognized properly, leading to potential discrepancies in how the game is played. Therefore, the role of the umpire in notifying of any lineup changes is crucial to maintaining the integrity of the game.
