Everett Aquasox

Following the 1983 season, Bob and Margaret Bavasi purchased the struggling Walla Walla, Washington, based Blue Mountain Bears. Antiquated facilities compounded by dwindling attendance in Walla Walla prompted the new owners to move the franchise. The Bavasis, who had secured affiliation with the San Francisco Giants, ultimately selected Everett as the relocation destination. Playing as the Everett Giants, the club was affiliated with San Francisco for eleven years until 1994. After the 1994 season, Everett signed a player development contract with the Seattle Mariners as their Class A Short Season affiliate and adopted a new unique name, the AquaSox. Since the 2021 season, the team has played at the High-A classification as a Mariners affiliate, initially in the High-A West. In March 2022, the High-A West was rebranded back to the Northwest League, as MLB moved to revert all of its Minor Leagues to their historical names.
