Summer Britcher, the Baltimore-born teenager, finished in 15th place in the women's singles luge event as her American teammate made history.
Britcher, 19, ended with a time of 3 minutes, 24.143 seconds after her four runs, which was 4.38 seconds behind gold medal winner Natalie Geisenberger of Germany (3:19.768).
The United States' Erin Hamlin, meanwhile, won the bronze after finishing in a time of 3:21.145, becoming the first American singles luger to ever medal at the Olympics.
Germany's Tatjana Huefner took the silver medal in a time of 3:20.907. Kate Hansen, the United States' third participant in the event, placed 10th with a time of 3:22.667.
Mark Grimmette, director of the USA Luge Sport Program, said before the Olympics about Britcher's expectations that, "finishing in the top 10 [in Sochi] would be great for her; finishing in the top 15 would be a solid result."
