Seattle Mariners

The Seattle Mariners play at T-Mobile Park, a retractable-roof ballpark celebrated for its view of the Seattle skyline and Puget Sound. The Mariners have been home to some of the greatest individual talents in baseball history, from Ken Griffey Jr. to Ichiro Suzuki. Seattle's Pacific Northwest fan base is known for its loyalty even through long playoff droughts. The franchise's teal-and-navy identity is a fixture of the American League West.

Founded as an expansion team in 1977, the Mariners set the American League record for wins in a season with 116 in 2001, powered by Ichiro's rookie MVP campaign. The franchise also produced the 1995 "Refuse to Lose" team that saved baseball in Seattle and helped secure funding for a new ballpark. Despite Hall of Fame-caliber players like Griffey, Ichiro, Randy Johnson, and Edgar Martinez, the Mariners are the only original MLB franchise never to reach a World Series. The team snapped a 21-year playoff drought in 2022.
