LAKE PLACID, N.Y. — Katie Uhlaender has given the United States its second gold medal at the skeleton world championships since the women's competition debuted in 2000.

Uhlaender, of Breckenridge, Colo., finished the four heats over two days at Mount Van Hoevenberg in 3 minutes, 42.33 seconds. She beat Mellisa Hollingsworth of Canada by 0.17 seconds on Friday.

Uhlaender also won silver at worlds in 2008 in Altenberg, Germany, and bronze the previous year in St. Moritz, Switzerland, when teammate Noelle Pikus-Pace won.

Elizabeth Yarnold of Britain took the bronze, 0.36 behind and just ahead of teammate Shelley Rudman, the World Cup champion. Olympic champion Amy Williams of Britain was fifth and two-time defending world champion Marion Thees of Germany was sixth.

Annie O'Shea of Port Jefferson Station, N.Y., finished 10th.
