Which scenario describes a legal substitution?

• A. A player re-enters the game in the wrong position in the batting order.
• B. A player eligible to enter or re-enter the game does so without reporting.
• C. A player for whom the DH is batting enters the game as a batter in a different position than the DH.
• D. None of the above.

Answer: (B)

Substitutions are allowed whenever the entering player is eligible to participate and the change fits the lineup and DH rules. In this scenario, the player who is eligible to enter or re-enter the game takes part in the game. Since the player is entering as allowed by eligibility and is filling a legal role in the lineup, this counts as a legal substitution. The other situations disrupt the batting order or the designated hitter rules, which would make substitutions illegal.
