Seventeen-year-old American Claressa Shields won the Olympic women's boxing middleweight gold medal on Thursday, capping her swift rise to the top of women's boxing with a 19-12 victory over Russia's Nadezda Torlopova.
Shields shuffled, danced and slugged her way past her 33-year-old opponent and even stuck her tongue out at Torlopova after ducking a few punches.
Torlopova took the silver while semi-final losers Marina Volnova of Kazakhstan and and China's Li Jinzi got bronze medals.
Shields won the 12-member American team's only gold medal in London. The most successful nation in Olympic boxing history got no medals from its men's team for the first time, and flyweight Marlen Esparza won a bronze.
