What must an umpire record regarding team warnings during a game?

Recording all warnings for future reference is important because it ensures a comprehensive account of the game's officiating decisions. This is essential in maintaining the integrity of the game and providing a clear historical record that can be referenced later if necessary.

By documenting each warning, umpires can track repeated offenses by teams or individual players, which can help enforce rules consistently and fairly throughout the game. This practice also serves as a safeguard for the umpire's decisions, as it allows for transparency in officiating. In instances where disputes may arise regarding warnings issued, having a detailed record can clarify what transpired during the game.

Overall, the documentation of all warnings enhances the professionalism of the officiating process and aids in the smooth conduct of future games.
