Carlos De León, also known as "Sugar" De Leon, (born May 3, 1959) is a Puerto Rican former boxer who made history by becoming the first Cruiserweight to win the world title twice. Subsequently, he kept breaking his own record for the most times as Cruiserweight champion by regaining it twice more.
He defended his title against Álvaro Yaqui López by a knockout in four at San Jose, California, and with decisions over Anthony Davis, José María Flores Burlon, and Bashiru Ali. The Davis and Burlon bouts took place in Las Vegas and the fight with Ali was in Oakland, California. De León next lost his title in Las Vegas to Alfonzo Ratliff by a decision. Ratliff was in turn beaten by Bernard Benton, who defended against De León on March 22 of 1986, once again in Las Vegas. De León joined the likes of Sugar Ray Robinson and Muhammad Ali in becoming one of the few boxers ever to win one division's world championship at least three times, defeating Benton by decision. He made a couple of defenses in Italy and then in 1988, lost his title in an unification bout with WBA world champion Evander Holyfield, by a knockout in eight, also in Las Vegas.But Holyfield soon left the division to pursue the world Heavyweight championship, and De León was left with an open door to break his own record and win the title for a record fourth time. He went to London, where he beat the WBC's number 2 challenger, Sammy Reeson (boxer), by a knockout in the Ninth round, breaking his own record and crowning himself world Cruiserweight champion once again. This time, he held on to the title for two years, until losing it to Massimiliano Duran in Italy by an 11 round disqualification.
During the 1990s, De León ran afoul of the law a number of times, once while he was carrying a rifle. Today, he concentrates on helping the career of his son Carlos De León Jr.
