In the case of a courtesy runner for the catcher, what is required for this arrangement to proceed?

In the context of using a courtesy runner for the catcher, the rule requires that any such arrangement must receive approval from the state association governing the sport. This is because the use of courtesy runners can vary by state and specific rules may be in place to ensure fair play and maintain the integrity of the game.

The necessity for state association approval ensures that there is uniformity in how rules are applied, avoiding discrepancies that could arise from individual teams' or coaches' preferences. By seeking this higher-level approval, the gameplay remains consistent with state regulations and guidelines, which is crucial for maintaining standards across competitions.

Other choices, such as approval from the opposing team's coach or a consensus among players, do not provide the same level of governing authority as the state association. These informal agreements could lead to misunderstandings or conflicts during the game. Furthermore, requiring an umpire ruling before the game starts is meant for game-specific rule clarifications, but it does not address the overarching authority that the state association holds over the rules in question.
