The Mariners and Rays were both eliminated in the first two rounds, and after their 4-3 loss to the Phillies in Game 5 of the National League Championship Series, the Padres' playoff run also came to an end. All have tasted success over the years, but none has won it all.
Here is a look at the half-dozen clubs whose fans are still waiting to celebrate, in order of how long each has been in its current home market.
The Rays don't have a lengthy history like some of the other clubs on this list, although they have reached the World Series twice. They won their first AL pennant in 2008 before bowing out to the Phillies in a five-game World Series. Tampa Bay claimed its second pennant in '20, but lost in six games against the Dodgers.
The Rockies clinched consecutive postseason berths for the first time in franchise history in 2017 and '18, but they didn't win a single playoff game in either run. In fact, over their three playoff appearances (they also reached in '09 as the National League Wild Card) since reaching the World Series in the well-revered "Rocktober" of '07, Colorado has only one won postseason contest since its NL-pennant clinching win against Arizona; the Rox were swept by the Red Sox in that year's World Series. The Rockies have never won the NL West, though they did force a Game 163 against the Dodgers in '18 for the right to win what would've been their first division title.
The Mariners have not only never appeared in a World Series, but they were riding the longest playoff drought in any of the four major pro sports, at 20 seasons, before snapping that this year. Seattle has had some of the game's biggest superstars through the years -- Ken Griffey Jr., Alex Rodriguez, Randy Johnson, Ichiro Suzuki and many more -- but it has also had some of the postseason's biggest disappointments, most notably in 2001, when the Mariners set an MLB record with 116 wins (a feat some suggest may never been matched), yet lost to the Yankees in the ALCS in just five games.
Rangers fans have had some of the most agony lately among clubs on this list, particularly given that their five postseason appearances since 2010 have failed to produce a title. Prior, they had made the postseason only three times -- including their time as the Washington Senators, who were founded in 1961. Texas was twice a strike away from winning the title in Game 6 of the '11 World Series against St. Louis, and the Rangers lost in five games to a Giants team that simply got hot at the right time in 2010. They also lost the 2012 AL Wild Card Game at home to the Orioles and were knocked out of the ALDS by the Blue Jays in '15 and '16.
The Brew Crew has made it to only one World Series -- a memorable seven-game loss to the Cardinals in 1982 with the "Harvey's Wallbangers" team -- and that was when they were in the AL. They nearly made it back in 2018, taking the Dodgers all the way to Game 7 of the NL Championship Series.
The Friars have reached the World Series twice, but both times they ran up against buzzsaws. The first was a dominant Tigers team that beat Tony Gwynn and Steve Garvey's Padres, 4-1, in the 1984 World Series, and the second was a sweep at the hands of the incredible '98 Yankees, who won 114 games in the regular season and are considered among a handful of teams as the greatest of all-time.
