Georgia requested (through the proper channels) a ruling from Mary Struckhoff, rules editor for NFHS, and was told that a courtesy runner absolutely could and should be allowed for F1 or F2 in the ITB.

The language "(or earn their way on base)" is an either/or statement, and is to be used as an alternative to "must bat and reach base legally". F1 and F2 earn their way on base the absolute same way every other player does in ITB; by virtue of being the player scheduled to bat 9th in the new inning. The language "must bat and reach base legally" is language meant to make clear that entering F1 or F2 to run for a DP or a sub cannot then lead to a courtesy runner; in that case, F1 or F2 met neither condition of the either/or statment.
