Milwaukee Brewers Reverse World Series Curse
The Milwaukee Brewers Reverse World Series Curse (or the Brewers World Series Curse) is a baseball-related superstition that derives from the fact that every baseball team that the Milwaukee Brewers lost to in the postseason made it to the World Series. The reverse curse is notable for its ironic twist, where the team defeating the Brewers is propelled to the World Series.
