Hagler was one of the greatest boxers in the 70’s and 80’s, and was the undisputed middleweight champion from 1980 until his loss to “Sugar” Ray Leonard in 1987. American Hagler fought 67 times over 14 years as a pro out of Brockton, Massachusetts, finishing 62-3-2 with 52 knockouts. His wife, Kay, made a post confirming his death on a Facebook page for her husband’s fans. “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,” she wrote.
