Seattle Mariners Overview
The Seattle Mariners are a Major League Baseball team based in Seattle, Washington. Established in 1977, they compete in the American League West Division and play their home games at T-Mobile Park. Known as the M’s, the Mariners sport team colors of navy blue, metallic silver, Northwest green, royal blue, yellow, and cream. The franchise has won four division championships in 1995, 1997, 2001, and 2025 but has yet to secure a World Series title. Owned by John Stanton, the team is recognized for its strong fan culture, iconic players, and the mascot Mariner Moose.
Founding and Organizational Origins
The Mariners were created following a lawsuit by the city of Seattle and the state of Washington after the Seattle Pilots relocated to Milwaukee in 1970. Confident that Major League Baseball would return, King County built the Kingdome, which became the Mariners’ original home. The team name was selected from over 600 submissions in a contest, with the winning entry submitted by Roger Szmodis of Bellevue, Washington. The Mariners began play in 1977, initially wearing blue and gold colors and playing at the Kingdome.
Growth Into American League Competition
The Mariners joined the American League as an expansion team in 1977. Early years were marked by struggles, with the team not posting a winning record or finishing above fourth place in their division for 14 seasons. Ownership changes occurred in the 1980s and early 1990s, culminating in Nintendo of America purchasing the team in 1992. The hiring of Lou Piniella as manager in 1993 marked a turning point, bringing stability and competitive success. The Mariners adopted their current team colors and began building a competitive roster.

The Mariners fielded their first winning team in 1991, setting the stage for playoff appearances in 1995, 1997, 2000, and 2001.

The 2001 season was historic, with the Mariners winning 116 games, setting an American League record and tying the Major League record for most wins in a season. Ichiro Suzuki’s MVP and Rookie of the Year awards highlighted this era.
Modern Program and Current Direction (2002–Present)
After the 2001 peak, the Mariners experienced a playoff drought until 2022. Ownership transitioned to John Stanton in 2016, with Jerry Dipoto as president of baseball operations and Justin Hollander as general manager.
