Page Notes  
Major League Baseball Franchises have working agreements with minor league teams (known as affiliates) across North America. These teams mostly operate independently but are stocked with players from the Major League organization as decided by the General Manager and the Baseball Operations department of a team. Player movement between teams (Promotions/demotions) are also managed by the MLB parent.

Select a franchise to view their history of minor league affiliates (1977 or later)
