It was 1975 when our league was created using a hi-low format for 12 teams. Each team was assigned two Major League Baseball teams that assigned first year carded players. In 1990 we decided to improve our rookie draft by allowing just one MLB affiliation for first year carded players. In 2000 we eliminated the MLB affiliation format and placed all first year carded players in our annual draft. As Major League Baseball expanded we did too and currently we have 15 teams in a three division format. We continue today as one of APBA's oldest leagues and as always we only use the APBA Basic game with cards and dice. You can learn more about our league by using the links at the top of this page to view our history, records, constitution plus sounds of the game of baseball. On our tribute page you will see why we honor Roberto Clemente and our three division namesakes.
