In 1979 a fourth Triple-A league started up business, joining the International League, Pacific Coast League and then-still-existing American Association. It was called the Inter-American League. It had no big league affiliations, but it was sanctioned by Major League Baseball.
Former big leaguers like Tom House, Mike Cuellar and Cito Gaston all played for Inter-American League teams which included one American team (the Miami Amigos) and five franchises based in the Caribbean: San Juan, Puerto Rico; Caracas, Venezuela; Maracaibo, Venezuela; Santo Domingo, Dominican Republic; and Panama City, Panama. It was the brainchild of Bobby Maduro, who worked as an assistant to MLB commissioner Bowie Kuhn. The plan was to play a 130-game schedule stretched over five months.
It’s quite a story. One team had a nice new tarp but didn’t know how to put it on the field. Another team forgot to send in box scores to the league office, so they couldn’t keep track of the stats. One team had a blank scoreboard sometimes because they only had one scoreboard operator and sometimes he worked nights. Many pitchers got special permission to only show up on days they pitched because they had day jobs selling shoes and stuff.
Obviously, the league folded. But Markusen’s story breathes new life into a long gone, quite weird little corner of baseball history. Go read it.
