Corrales entered the ring. His heart and determination could not be matched. One of the fiercest fighters of his time, he was a never-say-die warrior who consistently thrilled legions of fans with action-packed fights. A two-division champion, Corrales will be remembered most for his stunning come-from-behind knockout victory of Jose Luis Castillo to unify the lightweight titles on May 7, 2005 in an epic slugfest that was named Fight of the Year and hailed as one of the greatest fights in boxing history. Diego lived life to the fullest, as if every day was his last.
