When a game is protested, what must the protesting team do?

When a game is protested, it is essential for the protesting team to immediately inform the umpire of the protest. This action establishes the official recognition of the protest at the time it occurs, allowing the umpires to address the situation in real-time and potentially resolve the issue on the field. Immediate notice ensures that there is a proper record of the protest and the circumstances surrounding it, which is crucial for any follow-up actions that may need to be taken later by league officials or governing bodies.

Other options may involve steps that could be taken after the game or through formal channels, but they would not fulfill the immediate requirement of notifying the umpire. Without this initial step, the validity of the protest could be compromised, and proper protocols might not be followed.
