No!. In Major League Baseball, the Mariners are one of six teams who have never won a World Series championship, and they are the only club that has never participated in a World Series game.
The Seattle Mariners are an American professional baseball club headquartered in Seattle, Washington. They play in Major League Baseball as a member of the American League West division. In 1977, the franchise became an American League expansion team and played its home games at the Kingdome. T-Mobile Park, in Seattle’s SoDo area, has been the Mariners’ home field since July 1999.
Not only have the Mariners not participated in a World Series, but they also have the longest playoff drought of any of the four major professional sports, having gone 19 years without making the postseason. Through the years, Seattle has produced some of the game’s biggest stars, including Ken Griffey Jr., Alex Rodriguez, Randy Johnson, Ichiro Suzuki, and many others.
However, the city has also produced some of the sport’s biggest postseason disappointments, most notably in 2001, when the Mariners set an MLB record with 116 wins (a feat that some belief may never be matched) but were defeated by the Yankees in the American League Championship Series in five games.
