The league features an 80-game split-season that runs from June to August. First half winners face the second half winner in a one-game playoff (if needed) for the championship. On top of a salary, each player in the league is also provided housing accommodations and two meals a day six days a week.
During the initial season, two Hawaii-based teams, the Hawaii Stars and the Maui Warriors, played inter-league games against the Baseball Challenge League of Japan; California teams played against the Freedom Pro League of Arizona.
Both Hawaii teams, the Stars and the Warriors, ceased operations after playing the 2013 season due to the travel costs of bringing in opponents from Northern California. The East Bay Lumberjacks also did not return for a second season.
In 2017 San Francisco businessman and entrepreneur Jonathan Stone was named league commissioner.
