CHICAGO - Middleweight Matvey Korobov defended his 2005 title with a 29-4 win over Venezuela's Alfonso Blanco as Russian fighters contested six finals and came away with three titles at the World Boxing Championships on Saturday.
Bantamweight Sergey Vodopyanov beat Mongolia's Enkhbat Badar-Uugan 16-14 and featherweight Albert Selimov downed Ukrainian Vasyl Lomachenko 16-11 to round out the Russian medals.
Light-flyweight Zou Shiming of China and light-welterweight Serik Sapiyev of Kazakhstan repeated as champions. Shiming was a 17-3 winner over Harry Tanamor of the Philippines, and Sapiyev beat Russia's Gennady Kovalev 20-5.
Italy ended on a strong note, with heavyweight Clemente Russo narrowly outpointing Russia's Rakhim Chakhkeiv 7-6 and super-heavyweight Roberto Cammarelle beating the Ukraine's Vyacheslav Glazkov 24-14.
Flyweight Rau'shee Warren and welterweight Demetrius Andrade became the first Americans to win gold medals at the world championships in eight years with convincing victories.
Warren beat Thailand's Somjit Jongjohor 13-9 despite having two front teeth knocked out and Andrade's bout with Non Boonjumnong, also of Thailand, was stopped in the second round due to an injury.
Traditional power Cuba did not participate in this event.
Ukrainian light-heavyweight Abbos Atoev outpunched Artur Beterbiev of Russia 20-17 and Frankie Gavin of England beat Italy's Domenico Valentino 18-10 for the lightweight title.
Andrade went right at his opponent, landing combinations that resulted in a 6-0 lead and a standing eight count after the first minute, and he led 10-1 at the end of the round. He was ahead 11-3 late in the second when Non came up clutching his right arm, which had been bothering him.
Chicago hoped to use the World Boxing Championships as a boost in its bid for the 2016 Summer Games. Chicago did not get the championships until May after they were pulled from Moscow. - Sapa-AP
