Pivotal Works & Achievements

He holds the record for the sixth longest reign as champion in middleweight history. Nicknamed "The Marv" and annoyed that network announcers often did not refer to him as "Marvelous", Hagler legally changed his name to "Marvelous Marvin Hagler" in 1982. Hagler is an inductee of the International Boxing Hall of Fame and the World Boxing Hall of Fame. He was twice named Fighter of the Year by The Ring magazine and the Boxing Writers Association of America, as well as Fighter of the Decade (1980s) by Boxing Illustrated magazine. As of May 2026, BoxRec rates him the eighth greatest boxer of all time, pound for pound.
