Seattle Mariners history
Seattle's expansion club began play in 1977 and first called the Kingdome home. Since July 1999, home has been T-Mobile Park in the SoDo neighborhood, with room for 47,929. The name reflects the city's strong ties to the sea, and fans often call the club the M's. Royal blue and gold were the original colors until navy, teal and silver took over before 1993.
A first winning season arrived in 1991. The best stretch followed, with playoff trips in 1995, 1997, 2000 and 2001, led by Hall of Famers Randy Johnson, Edgar Martínez and Ken Griffey Jr.. In Game 5 of the 1995 division series, Martínez hit a double in the 11th inning that sent Griffey home from first to beat the Yankees, a moment credited with helping keep baseball in Seattle.
