Marvelous Marvin Hagler, boxing's middleweight champion for most of the 1980s, died "unexpectedly" at home in New Hampshire, his wife, Kay Hagler, said Saturday on social media. He was 66.
"Today unfortunately my beloved husband Marvelous Marvin passed away unexpectedly at his home here in New Hampshire," Kay Hagler said on her husband's Facebook fan page.
The cause of death was not disclosed. His official website Saturday was dedicated to his memory.
Hagler, who was born in 1954 in Newark, New Jersey, and raised outside Boston, got his first shot at the middleweight title in 1979 but was unsuccessful.
Then, in 1980, he knocked out champion Alan Minter for the title, which he would keep through 1987. He successfully defended it 12 times, notably against Roberto Duran and Thomas Hearns. His three-round war with Hearns in 1985 was dubbed fight of the year by The Ring magazine.
In 1987, he faced Sugar Ray Leonard and lost a split decision. When Leonard wouldn't grant a rematch, Hagler retired, according to the International Boxing Hall of Fame, which inducted him in 1993.
He had 62 wins, three losses and two draws when his career ended, according to Hagler's official site. He racked up 52 knockouts.
"Marvelous Marvin Hagler was among the greatest athletes that Top Rank ever promoted," Bob Arum, chairman of boxing promoter Top Rank, said in a statement. "He was a man of honor and a man of his word, and he performed in the ring with unparalleled determination. He was a true athlete and a true man. I will miss him greatly."
