What is the 40 man rule in MLB?

The 40 man rule in Major League Baseball (MLB) refers to the maximum number of players that a team can have on their roster during the regular season. This includes both active and inactive players. The purpose of the 40 man rule is to provide teams with flexibility and depth throughout the season. In MLB, teams typically have 25 active players on their roster for each game. However, during the regular season, teams can have up to 40 players on their 40 man roster. The additional 15 players beyond the 25 active players are known as the expanded roster. Teams often use these extra spots to call up players from their minor league system to gain experience and provide depth. For example, a team may call up a pitcher from the minor leagues to provide relief for the regular starting pitchers or to cover for injured players. It's important to note that the expanded roster only applies during the regular season. Once the playoffs begin, teams must submit a smaller roster, typically consisting of 25 players. This limited roster helps teams to maximize their best players and strategies during the most crucial games. Overall, the 40 man rule allows teams to have more options and flexibility throughout the regular season, ensuring they are equipped to handle injuries, fatigue, and various game situations.
