Aaron Pryor, the relentless junior welterweight who fought two memorable bouts with Alexis Arguello, died Sunday. He was 60.

Pryor’s family issued a statement saying the boxer died at his home in Cincinnati after a long battle with heart disease.

Known as “The Hawk,” Pryor was a crowd favorite who fought with a frenetic style, rarely if ever taking a step backward. His fights in the early 1980s with Arguello, the great Nicaraguan champion, were both classics that are still talked about in boxing circles.

But Pryor was a troubled champion, and his career would unravel because of an addiction to cocaine.
