Extra Player (EP) and/or Designated Hitter (DH)
At the beginning of a game, either the EP and/or the DH may be elected.
The Designated Hitter (DH) provision as covered in the rule book published by the National Federation of State High School Associations(NFHS) applies. The Extra Player (EP) is listed in the batting order and may assume any of the nine defensive positions without being counted as a substitution.
Under all of the following options, there are never more than the standard nine defensive positions. Options are:
1. Use neither the DH or EP, giving nine players in the batting order and the same nine players on defense.
2. Use only the DH, not the EP, giving nine players in the batting order, one of which is replaced by another line up player on defense.
3. Use only the EP, not the DH, giving ten players in the batting order of which nine play on defense.
4. Use both the DH and EP, giving ten players in the batting order, but one of the nine defensive players is replaced by the DH in that batting order. However, the DH can be removed during the game according to NFHS rules.
The same number of players listed in the batting order to begin the game continues throughout the game. If the game is started using an EP and/or DH, the game must be finished using an EP and/or DH.
Players not listed in the starting line-up may serve as substitutes in the normal manner as covered in the rule book.
In case of injury, the NFHS rule book applies except if an EP is being used and injury prevents that slot in the batting order form being filled, an automatic "out" applies in that slot.
