Our APBA league was created in 1975 using a hi-low format for 12 teams. Each team selected two Major League Baseball teams that would assign first year carded APBA players. In 1990 we improved 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 have 15 teams, in a three division format. We are proud to be not only one of APBA's oldest leagues but also to honor the great Roberto Clemente. We only use cards & dice in our league. 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 we honor the great Roberto Clemente and our three division namesakes.
