Cuba's Lazaro Alvarez, the world champion in the men's bantamweight (52-56 kg) boxing category, beat Brazil's Robenilson Vieira 16-11 on Sunday and was the only one of five Latin American boxers to ensure himself a chance for a medal.

Alvarez had to battle hard against an opponent who put up a lot of resistance, but his better punching combinations saw him through and landed him a place in the quarterfinals against Ireland's John Joe Nevin, who had defeated Mexico's Oscar Valdez 19-13.

The other two Latinos were in the heavyweight division, with Argentina's Yamil Peralta losing 13-10 to Bulgaria's Terver Pulev and Cuba's Jose Larduet losing 12-10 to Italy's Clemente Russo in a pair of tight bouts. EFE
