Minor League Baseball

Minor League Baseball (MiLB) is a hierarchy of professional baseball leagues in the Americas that compete at levels below Major League Baseball (MLB) and help prepare players to join major league teams. All of the minor leagues are operated as independent businesses. Most are members of the umbrella organization formally known as National Association of Professional Baseball Leagues (NAPBL), which operates under the Commissioner of Baseball within the scope of organized baseball. Several leagues, known as independent baseball leagues, have no official links to Major League Baseball.
