What is the requirement for baseballs provided to the umpire-in-chief?

The requirement that at least three new baseballs must be provided to the umpire-in-chief is essential for ensuring the game is played with high-quality equipment. New baseballs are crucial for maintaining play standards, as they ensure consistent performance in terms of grip, flight, and overall playability. The umpire-in-chief carefully manages the condition of the baseballs throughout the game, and having new balls readily available helps facilitate this.

Providing a minimum number of new baseballs allows for easy substitutions during the game, addressing any issues such as wear or damage that may arise. This provision supports the integrity of the game, as it minimizes interruptions and maintains a level playing field for both teams. While the specifics about which team supplies the balls or whether they are used are important, the key focus here is on the necessity of new baseballs being available for the game, making this requirement fundamental to the conduct of the match.
