In a situation where the pitcher appeals that R2 missed third base after a play, what is the ruling?

The ruling that the appeal is legal aligns with the rules governing baseball and softball regarding base running and appeals. In this scenario, if a runner (specifically R2) is believed to have missed touching a base—third base in this case—the defense (represented by the pitcher) is permitted to make an appeal regarding that infraction.

For an appeal to be valid, it must be made by a player on the defensive team, and it can be made by any player, including the pitcher. The essence of the appeal is that it draws the attention of the umpire to a potential rule breach concerning the base-running of R2. As long as the appeal is made in accordance with the rules, such as by properly notifying the umpire and doing so before the next pitch or play, the appeal stands as legal.

This understanding is critical for maintaining the integrity of the game and ensuring that all players are aware of and adhere to the rules regarding base running. When the pitcher appeals, it highlights the importance of player awareness and adherence to base-running protocols, which are foundational elements of the sport.
