Kitsap BlueJackets a West Coast League team. In 2017 he moved the WCL franchise to Port Angeles and they became the Port Angeles Lefties. The Kitsap BlueJackets became a semi-professional team, who compete in the Pacific International League (PIL) starting in 2017. The West Coast Guns were also members of the PIL. Thurston County Senators, an affiliated team who play a full league schedule, are not eligible for PSCL playoffs.
