The "minor leagues" refer to a system of professional sports leagues that serve as a developmental stage for athletes, particularly in baseball and hockey. These leagues provide young players with the opportunity to gain experience and improve their skills before potentially moving up to the major leagues, where the competition is more intense and the stakes are higher. In addition to baseball and hockey, minor leagues exist in other sports, such as basketball and soccer. Teams in these leagues are often affiliated with major league franchises, allowing players to be called up when needed. This system helps maintain a steady flow of talent into the major leagues.
