The New York State Public High Schools Athletic Association passed a pitch-count rule for baseball, effective this season, that will force pitchers to not pitch in a game until they have had a required number of nights off.
The days of rest varies based on the level of play and the number of pitches. For example, a varsity pitcher who throws between 1 and 30 pitches must take one night off, 31-65 pitches requires two nights off, 66-95 pitches forces pitchers to take three nights off, and 96-105 pitches must be followed by four nights off. Junior varsity and modified games have even stricter rules.
The numbers are eased slightly in postseason; a Varsity pitcher may throw up to 125 pitches in a game in the playoffs. Any team violating the rule must forfeit the game.
