Alex Rodriguez's suspension, announced Monday by the Commissioner's Office, is assuredly historic. It isn't quite unprecedented.
Bans of a season or more are not all that common in major sports, but they do occur. In hopes of providing a bit of context for Rodriguez's situation, MLB.com compiled a list of notable major suspensions in sports.
The list is not intended to be comprehensive, but instead to highlight some of the more prominent, noteworthy, lengthy suspensions in major sports over the years.
1921: The "Black Sox": Eight members of the 1919 Chicago White Sox were first suspended, and then permanently banned, for throwing the World Series against the Reds. The players, most prominent among them "Shoeless" Joe Jackson, were acquitted in a trial, but subsequently banned by Commissioner Kennesaw Mountain Landis nonetheless.
1947: Leo Durocher: The fiery, controversial manager of the Dodgers was suspended for the entire 1947 season by Commissioner "Happy" Chandler for "the accumulation of unpleasant incidents," including his association with people involved in gambling.
