In 1958, Moore had 10 fights, going 9–0–1 during that span. His fight with Yvon Durelle in particular was of note: defending his world light heavyweight title in Montreal, Quebec, Canada, he was felled three times in round one, and once again in round five, but then dropped Durelle in round 10 and won by a knockout in the 11th. 1959, his last full year as uncontested champion, was another rare low-profile year; in his two fights, he beat Sterling Davis by a knockout in three, and then Durelle again, also by a knockout in three, to once again retain his World Light Heavyweight title.
