Just as the Suggested Speed-Up Rules for courtesy runners are found in the back of the rule book, the case book plays for courtesy runners can be found in the back of the NFHS Case Book. Also, keep in mind that each state association can adopt any, all, or any part of the suggested speed-up rules. Here are three case plays to illustrate the rules.
CR 1 SITUATION: Team A’s courtesy runner runs for F1 and later in that same half-inning runs for F2. RULING: The courtesy runner can run for one or the other, but not both. This is an illegal substitution and shall result in the courtesy runner being declared out and restricted to the bench/dugout.
CR 6 SITUATION: McCormick is a courtesy runner for F2 in the first inning. He then is a courtesy runner for F1 in the sixth inning. RULING: Illegal. The same player cannot be a courtesy runner for both positions. The illegal substitute is declared out and restricted to the bench/dugout.
CR 14 SITUATION: Cook is a courtesy runner for the pitcher. He then pinch hits for the uninjured shortstop in the same half-inning. RULING: Cook is an illegal substitute and is declared out. He is restricted to the dugout for the remainder of the game. If he had previously been restricted to the dugout, he is out and ejected.
