Input: Question: How old was the fighter that De Leon beat in a comeback fight in 1983? Passage:De León, a native of Trujillo Alto, Puerto Rico, first won a world title when faced with WBC world champion Marvin Camel on November 25, 1980, at the undercard of Sugar Ray Leonard and Roberto Durán's second fight in New Orleans. De León outpointed Camel over 15 rounds. After he knocked out Camel in 8 in a rematch, countryman Ossie Ocasio won the WBA world title, becoming the second pair of Puerto Ricans to share world titles in the same division at the same time, after Alfredo Escalera and Samuel Serrano had achieved the feat in the 1970s at Jr. Lightweight. De León lost his title in a shocking upset to former Gerry Cooney victim S. T. Gordon by a knockout in round 2 at Cleveland in 1982, and won a comeback fight versus former world Heavyweight champion Leon Spinks by a knockout in round six in 1983. After that, he and Gordon boxed a rematch in Las Vegas, and De León dropped Gordon once in the first round and once in the twelfth, en route to a unanimous decision win in a history-making bout: De León had now become the first boxer to win the world Cruiserweight title twice.
