Seattle Mariners

The Seattle Mariners are a professional baseball team based in Seattle, Washington. Enfranchised in 1977, the Mariners are a member of the Western Division of Major League Baseball's American League. Safeco Field has been the Mariners' home ballpark since July 1999. From their 1977 inception until June 1999, the club's home park was the Kingdome.

The "Mariners" name originates from the prominence of marine culture in the city of Seattle. They are nicknamed "the M's", a title featured in their primary logo from 1987–1992. The current team colors are Navy Blue, Northwest Green (also known as dark cyan), and Metallic Silver, after having been Royal Blue and Gold from 1977–1992. Their mascot is the Mariner Moose.

The organization did not field a winning team until 1991, and any real success eluded them until 1995 when they won their first division championship and defeated the New York Yankees in the American League Division Series. The game-winning hit in Game 5, in which Edgar Martinez drove home Ken Griffey, Jr. to win the game in the 11th inning, clinched a series win for the Mariners, and has since become an iconic moment in team history.

The Mariners won 116 games in 2001, which set the American League record for most wins in a single season and tied the 1906 Chicago Cubs for the Major League record for most wins in a single season.

The Mariners are one of eight Major League Baseball teams without a World Series title, and one of two (along with the Washington Nationals) to never have appeared in a World Series.

Owned by Nintendo of America, the Mariners are one of three Major League Baseball teams under corporate ownership; the other two are the Atlanta Braves and the Toronto Blue Jays.
