Current Seattle Mariners domestic minor league affiliate locations

The Seattle Mariners farm system consists of six Minor League Baseball affiliates across the United States and in the Dominican Republic. Four teams are independently owned, while two others, the Arizona Complex League Mariners and Dominican Summer League Mariners, are owned by the major league club.

The Mariners have been affiliated with the Triple-A Tacoma Rainiers of the Pacific Coast League and High-A Everett AquaSox of the Northwest League since 1995, making them the longest-running affiliations in the organization among teams not owned by the Mariners. Their newest affiliate is the Inland Empire 66ers of the California League, which will become the Mariners' Single-A affiliate in 2026.

Geographically, Seattle's closest affiliates are the Tacoma Rainiers, which are approximately 26 miles (42 km) away, and the Everett AquaSox, which are approximately 27 miles (43 km) away. Seattle's furthest domestic affiliate is the Arkansas Travelers, 1,781 miles (2,866 km) away.

1977–1989

Prior to the 1963 season, Major League Baseball (MLB) initiated a reorganization of Minor League Baseball that resulted in a reduction from six classes to four (Triple-A, Double-A, Class A, and Rookie) in response to the general decline of the minors throughout the 1950s and early-1960s when leagues and teams folded due to shrinking attendance caused by baseball fans' preference for staying at home to watch MLB games on television. The only change made within the next 27 years was Class A being subdivided for the first time to form Class A Short Season in 1966. ^[2]

1990–2020

Minor League Baseball operated with six classes from 1990 to 2020. In 1990, the Class A level was subdivided for a second time with the creation of Class A-Advanced. The Rookie level consisted of domestic and foreign circuits. ^[2] The Venezuelan Summer League started in 1997, with the Mariners adding an affiliate in 2002, and folded after the 2015 season. ^{[17] [18]}

2021–present

The current structure of Minor League Baseball is the result of an overall contraction of the system beginning with the 2021 season. Class A was reduced to two levels: High-A and Low-A. The Everett AquaSox, which had been a Class A Short-Season team, were promoted to High-A, and the West Virgina Power lost their affiliated status. ^[52] Low-A was reclassified as Single-A in 2022. ^[53]

The Mariners sold the Single-A Modesto Nuts at the end of 2024, and new owners Diamond Baseball Holdings announced the team would move to San Bernardino and become the Inland Empire 66ers beginning in the 2026 season. ^{[54] [55]}
