The 1919 World Series featured the Black Sox Scandal, involving charges against several members of the Chicago White Sox and various gamblers for allegedly conspiring to throw the World Series games.
The underdog Cincinnati Reds beat the heavily favored White Sox to win the best-of-nine World Series five games to three. Two years later, eight players from the White Sox were banned from baseball for allegedly fixing the series even though they were acquitted of any criminal charges.
