Seattle Mariners

At a Glance

Introduction

The Seattle Mariners joined Major League Baseball as an expansion franchise in 1977, bringing the sport back to Seattle after the Seattle Pilots departed for Milwaukee following the 1969 season. The Mariners struggled to find sustained success during their early years, but the franchise’s fortunes began to change dramatically in the 1990s with the emergence of stars such as Ken Griffey Jr., Edgar Martinez, Randy Johnson, and Jay Buhner. Seattle reached the postseason for the first time in 1995, producing one of the most memorable playoff runs in baseball history and helping secure the long-term future of Major League Baseball in the city.

The Mariners have remained in the American League West throughout their history and have produced some of baseball’s most accomplished and distinctive players. Ichiro Suzuki became an international icon after arriving from Japan in 2001, the same season Seattle won an American League-record 116 regular-season games. Félix Hernández later became one of the premier pitchers of his generation, highlighted by his 2010 Cy Young Award and perfect game in 2012. Although the Mariners are still pursuing their first World Series appearance and championship, their history includes record-setting teams, Hall of Fame players, and some of the most recognizable stars of the modern era. This hub brings together the franchise’s greatest players, historic seasons, statistical leaders, all-time rosters, and other resources covering the history of the Seattle Mariners.
