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.
Before the 2019 season the league lost two teams, Martinez and Pittsburg, which both folded and replaced by Pecos League teams in 2020. To replace them the Salina Stockade were added to the league as a travel team.
Prior to the 2020 season, San Rafael left the league for the Pecos League and were replaced by the California Dogecoin. The Salina Stockade moved back to The Western League, bringing the Pacific Association back down to four clubs. After the season was postponed by the COVID-19 pandemic, the Dogecoin were removed from the league website without having played a game. The 2020 season was officially cancelled on July 17, 2020. Later, the California Dogecoin joined the inaugural season of the Liberation Professional Baseball League.
