(b) Relievers and Reliever/Starters can enter a game fatigued in the 7th inning or after and pitch for a maximum of 1 inning. (c) All pitchers are allowed to pitch fatigued only once in a series (and once during the regular season). (d) Starting lineups must include players eligible at each position. Exception: injuries.
