Winning the World Series is the ultimate achievement in Major League Baseball, but not every franchise has experienced that moment. While organizations like the New York Yankees, Los Angeles Dodgers, and St. Louis Cardinals have celebrated multiple championships, others have spent decades trying to capture their first title.
As of now, five of the league's 30 teams have never won a World Series. Some have come agonizingly close, reaching the World Series before falling short. Others have endured historic regular-season success without advancing to baseball's biggest stage.
Here's a closer look at the MLB teams still seeking their first World Series championship, their greatest postseason accomplishments, and the moments that have defined their championship droughts.
The Seattle Mariners hold an unfortunate distinction in Major League Baseball history. They are the only active MLB franchise that has never appeared in a World Series.
Seattle entered the American League in 1977 and spent nearly two decades waiting for its first postseason appearance. That breakthrough came in 1995, when a roster featuring Ken Griffey Jr., Edgar Martinez, and Randy Johnson captured the AL West title. The Mariners defeated the Yankees in a memorable five-game AL Division Series before losing to Cleveland in the American League Championship Series.
Seattle's most remarkable season came in 2001. Led by Ichiro Suzuki, Bret Boone, and a deep pitching staff, the Mariners finished with 116 regular-season victories, tying the all-time MLB single-season wins record established by the 1906 Chicago Cubs. Despite that extraordinary achievement, Seattle lost the ALCS to the Yankees in five games.
The franchise suffered another devastating disappointment in 2025. Seattle reached Game 7 of the ALCS against the Toronto Blue Jays and held a late lead before George Springer's three-run home run helped Toronto secure a 4-3 victory.
The Mariners entered 2026 still searching for their first pennant and ultimately missed the postseason, extending their wait for another opportunity. Based on their history, making MLB predictions on the Mariners to win an upcoming World Series is a difficult position to justify.
The Milwaukee Brewers have experienced sustained periods of success, but their only World Series appearance came in 1982, when the franchise was still competing in the American League.
That Brewers team, nicknamed "Harvey's Wallbangers," featured an intimidating offense led by Robin Yount, Cecil Cooper, and Paul Molitor. Milwaukee defeated the California Angels in the ALCS and advanced to face the St. Louis Cardinals in the World Series. The Brewers pushed the Cardinals to seven games but ultimately lost the championship-deciding contest, ending their best opportunity to capture a title.
Milwaukee moved to the National League in 1998 and has since developed into a frequent postseason contender. In 2018, the Brewers came within one victory of returning to the World Series but lost Game 7 of the NLCS to the Los Angeles Dodgers. The franchise enjoyed another deep postseason run in 2025, advancing to the NLCS before being swept by the Dodgers.
Milwaukee's championship drought is particularly notable because the organization has repeatedly built competitive teams without securing the final postseason breakthrough. They continue to try to earn the NL pennant and World Series title that they desperately want.
The San Diego Padres have reached the World Series twice, but both appearances ended in defeat against historically formidable opponents.
Their first opportunity came in 1984, when a team featuring Tony Gwynn and Steve Garvey won the National League pennant. San Diego faced a Detroit Tigers team that had dominated the regular season with 104 victories. The Tigers won the World Series in five games, leaving the Padres without their first championship.
Fourteen years later, San Diego returned to the Fall Classic behind another outstanding roster featuring Gwynn, Kevin Brown, and Greg Vaughn. Unfortunately for the Padres, their opponent was the 1998 New York Yankees, a team that won 114 regular-season games and went on to sweep San Diego in four World Series contests.
More recently, the Padres made an impressive run during the 2022 postseason. They defeated the New York Mets in the Wild Card Series and eliminated the rival Dodgers in the NLDS. However, their championship hopes ended with a five-game NLCS loss to the Philadelphia Phillies.
San Diego entered the 2026 postseason still looking to deliver the first World Series title in franchise history. But they were cut down by the Milwaukee Brewers in the Division Series. Despite two pennants and several memorable playoff runs, the Padres remain one of baseball's longest-standing championship hopefuls.
The Colorado Rockies joined Major League Baseball as an expansion franchise in 1993 and reached their first postseason just two years later. However, their most memorable achievement came in 2007, during an extraordinary late-season surge remembered as "Rocktober."
Colorado won 14 of its final 15 scheduled regular-season games and then defeated the San Diego Padres in a dramatic tiebreaker to claim the National League Wild Card. The Rockies carried that momentum into October, sweeping the Philadelphia Phillies in the NLDS and the Arizona Diamondbacks in the NLCS.
Their remarkable run included seven consecutive postseason victories and earned Colorado its first National League pennant. Unfortunately, the Rockies encountered a Boston Red Sox team that ended their winning streak and swept the World Series in four games. Colorado has struggled to replicate that postseason success.
The Rockies returned to the playoffs in 2009, 2017, and 2018, but none of those appearances produced another trip to the NLCS. The franchise has also never won the NL West division title, making its 2007 pennant run even more distinctive.
Colorado's 2007 season remains one of the most dramatic championship pursuits by a franchise that has never won the World Series.
The Tampa Bay Rays are the youngest franchise among the five teams without a World Series title. Originally known as the Tampa Bay Devil Rays, the franchise began playing in 1998 and endured ten consecutive losing seasons before its breakthrough in 2008.
That year, Tampa Bay won 97 regular-season games, captured the AL East title, and advanced through the postseason to reach its first World Series. The Rays ultimately lost to the Philadelphia Phillies in five games, but the season established the franchise as a legitimate contender.
Tampa Bay returned to the World Series in 2020 after finishing the shortened regular season with an American League-best 40-20 record. Led by a strong pitching staff and a roster featuring Randy Arozarena, the Rays defeated the Houston Astros in seven games to win the AL pennant.
Their championship hopes ended against the Los Angeles Dodgers, who captured the World Series in six games. The Rays have reached two World Series despite operating with financial resources that have frequently been more limited than those of baseball's biggest-spending organizations. The question is whether that lack of spending will prevent them from ever winning the World Series.
