On the surface, it appeared to be a great day for the United States, picking up the silver and bronze medals in the bobsled.
However, after taking the lead into the fourth and final run, the United States could not close the deal and allowed Canada to take home the gold medal.
Lauryn Williams and Elana Meyers had an excellent push to start their final run, but they quickly ran into trouble at the top of the Sanki Sliding Center, and their lead over Canada's Kallie Humphries and Heather Moyse quickly evaporated. When Williams and Meyers continued to bang their sled into the sidewalls, their fate as non-gold medal winners was sealed.
Humphries and Moyse finished with a time of 3:50.61, and that gave them an edge of .10 over Williams and Meyers. The U.S. team of Aja Evans and Jamie Greubel finished in 3:51.61, and they took home the bronze medal.
The third American team of Jazmine Fenlator and Lolo Jones finished in 11th. That teams was expected to do the best of the three American bobsled teams, but they struggled during the first day of competition and could not climb in the standings.
Gold: Kallie Humphries and Heather Moyse, Canada, 3:50.61
Silver: Lauryn Williams and Elana Meyers, United States, 3:50.71
Bronze: Aja Evans and Jamie Greubel, United States, 3:51.61
Update by Steve Silverman
The highly publicized transition of American Lolo Jones from Summer Olympics star to Winter Games competitor created headlines, but it's her U.S. teammates who are in premier position to reach the podium.
Lauryn Williams and Elana Meyers lead all contenders through the first two of four total runs. "Lauryn has had so much Olympic experience, and I'm so confident in her abilities," Meyers said, via ESPNW's Jim Caple. "It will be fun to go out No. 1 and throw something down."
Fellow U.S. racers Aja Evans and Jamie Greubel secured the third-fastest time.
Jones settled for an 11th-place effort on Tuesday.
Canada's Kaillie Humphries and Heather Moyse are sandwiched by the Americans in second place. Humphries earned a gold medal at the 2010 Vancouver Games.
Veteran Sandra Kiriasis leads Germany. The 39-year-old hopes to recapture the magic of her 2006 gold medal in Torino.
Kiriasis begins Wednesday in fifth place.
Gold: Lauryn Williams and Elana Meyers, United States
Silver: Aja Evans and Jamie Greubel, United States
Bronze: Kaillie Humphries and Heather Moyse, Canada
