In the event an illegal player is involved in a game-ending double play, when must the offense report the discovery?

The correct response pertains to the specific timing of when the offense is required to report the discovery of an illegal player involved in a game-ending double play. Reporting this before all infielders have crossed the foul lines is crucial because it allows the umpires to take appropriate action in accordance with the rules of the game.

If the offense waits until after all infielders have crossed the foul lines, it may hinder the ability to address the situation correctly. Once the infielders are beyond these lines, the play is considered completed, and the opportunity to rectify the illegal player's involvement diminishes, leading to a potential loss of the right to protest the ruling.

Thus, timely reporting ensures that all procedural avenues remain open for the offense to leverage. It reflects the importance of proper game management and adherence to rules, facilitating fair play and maintaining the integrity of the game.
