Here is a look at the first day of the women's singles luge competition, which saw Natalie Geisenberger take a commanding lead in Sochi. American Erin Hamlin, who is in third place, will enter Sunday's competition with the chance to win the United States its first-ever medal in a luge event.
Erin Hamlin was third after the second run. No U.S. luger -- male or female -- has ever won a medal in a singles event.
Russian Natalia Khoreva finished the second run in fourth place, 0.216 seconds behind Erin Hamlin.
Geisenberger held a commanding lead -- 0.764 seconds -- over teammate Tatjana Huefner after the second run. Geisenberger and Huefner won bronze and gold, respectively, in 2010.
