Which of the following is a responsibility of the official scorer?

• A. Substitutes.
• B. Time delays.
• C. Reason for ejection.
• D. The batter-runner's advance due to error or base hit.

Answer: (A)

The official scorer’s job is to maintain the official scorebook, including tracking every substitution and logging who enters and leaves the game. Keeping an accurate record of substitutes is essential to preserve the correct batting order, eligibility, and the overall game record as it unfolds.

Time delays are handled by the umpires and game management, not the scorer. The reason for an ejection is decided by the umpire and then noted in the game report. While the scorer records outcomes of plays—like a batter-runner’s advancement on a base hit or an error—the explicit, ongoing responsibility to log substitutions is the clearest and most vital duty of the official scorer.
