1. The Red Sox Sell Babe Ruth To The Yankees
The franchise-cripplingest of franchise-crippling moves, the Boston Red Sox’s sale of Babe Ruth to the New York Yankees in January 1920 sent the team into a tailspin that’d take, according to the “Curse of the Bambino” superstition, a ridiculous 86 years to recover from. With the Yankees, the Babe led the American League in home runs 10 times and won four World Series.
