Great Britain's Luke Campbell beat Ireland's John Joe Nevin to win the men's bantamweight final in front of a home crowd.

Campbell beat Nevin 14-11 to highlight five title fights Saturday night at the London Olympics, saying afterward the crowd of 10,000 people inspired him to the victory.

"You can't describe the feeling. It's once-in-a-lifetime to be part of the Olympics and represent Great Britain," said Campbell.

World champion Oleksandr Usyk of the Ukraine beat Italian Clemente Russo 14-11 for the heavyweight gold medal, while No. 1 seed Zou Shiming of China defended his Olympic gold in the light flyweight with a 13-10 victory over Thailand's Kaeo Pongprayoon.

Cuba's Roniel Iglesias Sotolongo routed Ukrainian Denys Berinchyk 22-15 for the light welterweight title and Japan's Ryota Murata edged Brazil's Esquiva Falcao Florentino 14-13 for the middleweight gold.

Boxers who lost semifinal bouts in the weight classes both earned bronze medals.

Gold medals will be decided Sunday in five more weight classes, including the super heavyweight category.
