The Seattle Mariners have not made the postseason since 2001. It is the longest active streak of futility in Major League Baseball. Along with the Washington Nationals, they are also the only club to not have appeared in a World Series.
However, in 2018 the Mariners have a chance to end the curse that has grasped them for 17 grueling seasons. The good news is that with a 60-40 record through Jul. 24, the Mariners currently hold the second American League Wild Card spot. The bad news is that their grip on that spot is tenuous at best thanks to an upstart A’s squad that has been on a roll as of late.
