National Association of Professional Baseball Leagues
From BR Bullpen
In 1902, the National Association of Professional Baseball Leagues was formed as an umbrella organization for minor leagues. An agreement between the major leagues and the new minor league association was written. The new document established league classifications, roster and salary limits and a system for drafting players. It recognized reserve lists and created a Board of Arbitration that was given the power to suspend players, clubs, or officials for violations. Patrick Powers was elected first president. The organization changed its name Minor League Baseball in 1999.
