(Undated) -- Major League Baseball is attempting to trim down its labor force in the minor leagues. ESPN reports that the league wants to reduce the size of the Domestic Reserve List, which currently allows clubs to have up to 180 players in their minor league systems. The MLB is trying to gradually decrease the number of players to below 150 throughout the next collective bargaining agreement. In December of 2020, the league got rid of 42 minor league teams when it restructured the farm system.
