The Bambino
After winning the 1918 World Series, the Boston Red Sox shocked the baseball world by selling their star player Babe Ruth to their arch rivals, the New York Yankees. With this acquisition, the Yankees became a better team over the years, and the Red Sox would go an incredible 86 years without winning another World Series. Many blamed the sale of Ruth to New York for Boston's long lasting post season misfortunes, eventually referring to it as 'The Curse of The Bambino'.
In 2004 the curse would be finally broken, with Boston overcoming an 0-3 deficit and defeating the New York Yankees in four straight games. Boston would face St. Louis in the World Series, winning the series 4-0. Cardinals shortstop Edgar Renteria, who wore #3, which was Babe Ruth's number with the Yankees, hit into the final out of the game giving the Red Sox the Championship, finally putting 'The Curse of The Bambino' to rest.
