The Vallejo Admirals were founding members of the Pacific Association in 2013 and have been one of just two franchises, alongside the San Rafael Pacifics, to play all of the circuit's seasons. However, they almost did not complete their very first season, as they were dropped from the league for a spell in July because of financial troubles. They were able to clean things up, rejoined the league a short while later, and have been one of the most stable franchises in the circuit since then.
