What is the ruling if C1 is a courtesy runner for the catcher and then runs for the pitcher in the same game?

In this situation, the ruling is that the player, C1, is called out and restricted for the remainder of the game. This is because the NFHS rules specify that a courtesy runner may be used only once per inning for the designated player. C1, having originally been designated as a courtesy runner for the catcher, cannot then be used again to run for another player, in this case, the pitcher.

Using a courtesy runner more than once in a single inning for different players violates the established protocol, which is designed to ensure a fair and regulated flow of the game. Therefore, invoking this rule leads to the decision that the player must be called out for violating the courtesy runner rule, and they cannot participate further in that capacity until the game is over.

This ruling helps maintain the integrity of the game by prohibiting the inappropriate assignment of a single player to multiple relief roles in a way that could provide an unfair advantage.
