Brazilian fighter Adriana Araujo will have to be content with a bronze medal after losing to Russia's Sofya Ochigava here Wednesday in the women's lightweight boxing semifinal at the 2012 London Olympics.

Araujo started out attacking the current world No. 2 and the first round ended with the pair tied on points.

But Ochigava took the lead in the second round and went on to win, 17-11.

The Russian, who will go on to face reigning world champ Katie Taylor of Ireland in the final, was quicker on her feet and a more effective puncher than Araujo.

"Bronze is not what I wanted, but I'm leaving happy," Araujo said after the fight. "The next Olympic games will be in my country," she added, referring to Rio de Janeiro's role as host of the 2016 games, "but I won't be there because I'm going professional."

Araujo is the only Latin American competitor to win a medal in the debut of women's boxing as an Olympic event.

U.S. fighter Marlen Esparza lost in the women's flyweight semifinals to Ren Cancan of China, a three-time world champion.

Esparza, the 23-year-old daughter of Mexican immigrants, was the subject of an extensive profile last month in The Atlantic magazine. EFE
