When must defective equipment be repaired or replaced?

Defective equipment must be repaired or replaced immediately to ensure the safety of the players and the integrity of the game. When an umpire determines that a piece of equipment, such as a bat or helmet, does not meet the required standards or poses a risk, it is crucial for the issue to be addressed at once. This urgency reflects the importance of maintaining a safe environment during gameplay, as continued use of defective equipment can lead to injuries or unfair advantages.

Prompt attention to defective equipment also helps maintain the flow of the game, avoiding unnecessary delays that could disrupt the players' focus and the overall pacing of the match. Therefore, the immediate response is vital for upholding the rules and standards of play in baseball.
