permanently banned

A ban from Major League Baseball is a form of punishment levied by the Office of the Commissioner of Major League Baseball (MLB) against a player, manager, executive, or other person connected with the league as a denunciation of some action that person committed that violated or tarnished the integrity of the game. A banned person is forbidden from employment with MLB or its affiliated minor leagues, and is forbidden from other professional involvement with MLB such as acting as a sports agent for an MLB player. Since 1991, all banned people – whether living or deceased – have been barred from induction to the Baseball Hall of Fame.
Major League Baseball has maintained a list of "permanently ineligible" people since Kenesaw Mountain Landis was installed as the first Commissioner of Baseball in 1920. Although the majority of banned persons were banned after the establishment of the Commissioner's office, some were formally banned prior to that time while a few others were informally "blacklisted" by the Major League clubs. Most persons who have been banned (including many who have been reinstated) were banned due to association with gambling or otherwise conspiring to fix the outcomes of games; others have been banned for a multitude of reasons including illegal activities off the field, violating some term of their playing contract, or making disparaging remarks that brought the game into disrepute.
