SoCal, I stand corrected. NFHS 3-7-1 penalty reads a little vague. "After three charged conferences in a seven inning game, or for any conference in excess of one in each extra inning, the pitcher shall be removed as pitcher for the duration of the game." This could be written to clearly state that three defensive conferences are allowed in seven innings. Any further conferences will result in the removal of the pitcher as pitcher for the duration of the game. Or, Any defensive conference in excess of three in a seven inning game, or one per extra inning shall result in the pitcher being removed as pitcher for the duration of the game.
