The Major League baseball rule Pete Rose violated is: “Rule 21 MISCONDUCT, (d) BETTING ON BALL GAMES, Any player, umpire, or club or league official or employee, who shall bet any sum whatsoever upon any baseball game in connection with which the bettor has a duty to perform shall be declared permanently ineligible.”
Pete Rose voluntarily accepted a permanent place on baseball’s ineligible list. Rose accepted that there was a factual reason for the ban; in return, Major League Baseball agreed to make no formal finding with regard to the gambling allegations. According to baseball’s rules, Rose could apply for reinstatement in one year but Bart Giamatti said, “There is absolutely no deal for reinstatement. That is exactly what we did not agree to in terms of a fixed number of years.” Rose, with a 412–373 record, was replaced as Reds manager by Tommy Helms. Rose began therapy with a psychiatrist for treatment of a gambling addiction. Rose’s ban has prevented the Reds from formally retiring his No. 14 jersey.
