How should R1's new uniform number be handled after he changes jerseys?

When a player changes their jersey number, it is essential that this change is documented properly in both the scorebook and lineup card. This practice supports transparency and fairness in the game, ensuring that everyone involved, including officials, coaches, and scorekeepers, can accurately track the player's participation and contributions during the match. Recording the new number helps to avoid confusion and allows for proper identification of the player throughout the game.

Ensuring that changes like this are officially noted helps maintain the integrity of the game. Miscommunications regarding player identification can lead to disputes or issues with play. The option addressing only the umpire needing to be informed, or that the opposing coach's approval is necessary, does not cover the requirement for maintaining clear and organized records that benefit all teams involved in the competition.
