Under NFHS rules, courtesy runners are not allowed for designated hitters (DH).

• A. They are allowed if the opposing coach agrees.
• B. They are allowed for the DH at any time during the game.
• C. They are allowed if the umpire marks the courtesy runner and informs the opposing team.
• D. They are not allowed for the DH.

Answer: (D)

In NFHS baseball, courtesy runners are used to replace players who are currently on base and who would normally run, but there are limitations on who can be a courtesy runner. The designated hitter is a batting-only spot and does not participate in the field, so the rule does not allow a courtesy runner for the DH. This keeps the DH’s role simple and preserves the intended lineup structure without introducing an extra runner for the batting side. Therefore, courtesy runners are not permitted for the DH, regardless of any agreement or umpire action. The other options imply allowances that the NFHS rules do not provide for the DH.
