Claressa Shields, the youngest member of the United States boxing team, is the only one left standing at the London Olympics.

The 17-year-old from Flint, Mich., beat Kazakhstan’s Marina Volnova in the semifinals of the middleweight division on Wednesday to advance to Thursday's gold-medal match, where she will face 33-year-old Russian Nadezda Torlopova.

Shields, a senior-to-be at Northwestern (Flint, Mich.) who has been boxing since she was 9, beat Volnova 29-15.
