Seattle Mariners

The Seattle Mariners represent the Pacific Northwest from T-Mobile Park, a state-of-the-art retractable-roof stadium that has become one of baseball's finest venues since opening in 1999. The Mariners have built a devoted fanbase in a region known for its coffee culture, tech innovation, and outdoor lifestyle, with Seattle's isolation from other MLB cities creating a fiercely loyal following. The franchise's teal, navy, and silver colors reflect the Pacific Northwest's maritime heritage, while the organization has emphasized player development and building through the draft. T-Mobile Park's intimate design, quality sightlines, and retractable roof ensure great baseball regardless of Seattle's famously unpredictable weather. The Mariners continue their pursuit of the franchise's first World Series appearance, with recent playoff runs having rekindled hope in one of baseball's most passionate but title-starved markets.

Founded in 1977 alongside Toronto, the Mariners endured 14 losing seasons before Ken Griffey Jr.'s arrival transformed the franchise and made Seattle baseball must-see entertainment. The 1995 team's miraculous playoff run, featuring 'The Double' by Edgar Martínez that scored Griffey and saved baseball in Seattle, remains one of the sport's most iconic moments. The 2001 team won 116 games—tying the American League record—behind Ichiro Suzuki's historic rookie season, though they fell short in the playoffs. Randy Johnson's dominance, Félix Hernández's perfect game, and the sustained excellence of Martínez and Griffey created lasting memories despite the franchise's failure to reach a World Series. The 2022 playoff appearance ended a 21-year drought, and Julio Rodríguez's emergence has given Seattle hope for its first championship run.
