Marvelous Marvin Hagler, who dominated boxing's middleweight division in the 1980s, has died at the age of 66, his wife Kay Hagler said on Saturday.
Hagler, who legally changed his name to Marvelous in 1982, posted a record of 62-3-2 and ruled supreme until his reign as undisputed middleweight champion came to a controversial end in 1987 with a loss to Sugar Ray Leonard.
"I am sorry to make a very sad announcement. Today unfortunately my beloved husband Marvelous Marvin passed away unexpectedly at his home here in New Hampshire. Our family requests that you respect our privacy during this difficult time," Kay Hagler posted on the Marvelous Marvin Hagler Fan Club page on Facebook.
Regarded as one of boxing's great champions and best pound-for-pound fighters, Hagler was knocked down just once in 67 professional bouts while 52 of his wins came by way of knockouts.
