The franchise arrived in 1973 as the Bellingham Dodgers, affiliated with the Los Angeles Dodgers for four seasons. They changed to the expansion Seattle Mariners in 1977 (Bellingham Mariners, or the "Baby M's" as they were popularly known), which lasted for 18 seasons, through 1994. The final two seasons in 1995 and 1996 were as the Bellingham Giants, the affiliate of the San Francisco Giants.
After three seasons in Medford and one season in Spokane in 1972, the Dodgers moved their NWL affiliate to Bellingham for 1973. The team gained unwanted national notoriety in 1975 when it opened the season with 25 straight losses; they finished at 17–61 (.218).
In 1987, 17-year-old Ken Griffey, Jr. hit his first professional home run while on the road at Everett Memorial Stadium on June 18. A plaque was placed on the sidewalk outside the stadium where the ball landed.
Following the 1994 season, the Mariners moved their affiliation to the Everett AquaSox. After the 1996 season, the Bellingham Giants moved south to Keizer, Oregon, and became the Salem-Keizer Volcanoes in 1997.
