US Middleweight Claressa Shields defeated Kazakhstan’s Marina Volnova in the semis to advance to the gold medal bout against Russia’s Nadezda Torlopova in the Olympics first-ever female boxing competition, according to AP.

Shields defeated Volnova 29-15 in the fight.

"I'm still kind of shocked," Shields said. "I'm thinking in my head, 'Is it really true? Am I fighting for a gold medal tomorrow?'"

Shields is the last American boxer left standing in London after flyweight Marlen Esparza lost 10-8 to Chinese world champion Ren Cancan. Esparza will take home the bronze medal.

The Shields v Torlopova bout will take place on Thursday.
