Marvelous Marvin Hagler Marvelous Marvin Hagler (born Marvin Nathaniel Hagler; May 23, 1954) is an American former professional boxer who competed from 1973 to 1987. He reigned as the undisputed middleweight champion from 1980 to 1987, making twelve defenses of that title, and currently holds the highest knockout percentage of all undisputed middleweight champions, at 78%. At six years and seven months, his reign as undisputed middleweight champion is the second longest of the last century, behind only Tony Zale, who reigned during World War II. In 1982, annoyed that network announcers often did not refer to him by his nickname, "Marvelous", Hagler legally changed his name to Marvelous Marvin Hagler.
