text: List of Major League Baseball franchise postseason droughts
League division champion droughts -- Longest current division champion droughts
No league division champions were won in 1994 due to the players ' strike that year .
Throughout the history of Major League Baseball (MLB), franchises have had various postseason and World Series droughts. All 16 of the original Major League franchises (i.e., those in place when the first World Series was played in 1903) have won the World Series, with the longest wait for a franchise's first championship being for the Phillies (77 years, ending in 1980). Since expansion began in 1961, six of the 14 expansion teams have never won the World Series. Further, one franchise (the Indians) has a current championship drought that pre-dates the expansion era. The three longest championship droughts in history were ended recently by the Red Sox (85 years, ending in 2004), the White Sox (87 years, ending in 2005), and the Cubs (107 years, ending in 2016). Only one expansion franchise (the Mariners) has never won a pennant (i.e., the league championship, the two winners of which meet in the World Series). The three longest pennant droughts in history were recently ended by the Nationals (51 years, starting with the team's foundation and ending in 2019, and including the franchise's entire 36 years as the Montreal Expos), the Rangers (49 years, starting with the team's foundation and ending in 2010) and the Cubs (70 years, ending in 2016). As the Nationals are the third franchise to be based in the city of Washington, their 2019 pennant also ended a drought of 53 seasons played in Washington since their last pennant, which was in 1933 (here we discount the 33 seasons during which there was no team in Washington). Every MLB franchise has at least been to the postseason, especially since expansion of the playoffs in 1994 made that feat easier. The Mariners have the longest active postseason drought at 18 years. Long postseason droughts were ended recently by the Nationals (30 years for the franchise, 45 seasons over 78 years for the city, ending in 2012), the Pirates (20 years, ending in 2013), the Royals (28 years, ending in 2014), and the Blue Jays (21 years, ending in 2015). This list includes only the modern World Series between the American League (AL) and the National League (NL), not the various 19th-century championship series.
