Vonn, a part-time Park City resident, captured her milestone 50th World Cup win in a downhill on the same slope a day earlier. But she was forced to wait for her start for about three minutes while officials fixed a gate, and Vonn could not hold her line Sunday after hitting a bump midway down the icy piste. She was looking for a record 18th career super-G win.
Mancuso produced a clean run in freezing conditions, with bright sunlight and deep shadows alternating on the Kandahar course and making for poor visibility. She won on the same slope where she clinched the super-G silver medal at last year's World Championship.
"I thought when I crossed the finish line, 'If that wasn't good enough, then I don't know what is,' " Mancuso said.
Mancuso finished in 1 minute, 20.50 seconds. Anna Fenninger, of Austria, super-combined world champion here last year, was second, 0.13 seconds behind, and Tina Weirather, of Liechtenstein, was third, 0.45 back.
Weirather was also third in Saturday's downhill, while Maria Hoefl-Riesch, of Germany, last season's overall World Cup champion, finished fourth for the second straight day.
Men's super-combined • In Chamonix, France, Romed Baumann held off a strong challenge from promising Frenchman Alexis Pinturault to win Sunday's World Cup super-combined race for his second career victory. Baumann led Pinturault by a comfortable 3.27 seconds after posting the fastest time in the morning's downhill run on the La Verte des Houches course, and the Austrian held firm in the afternoon slalom session to win by 1.10 seconds.
Women's ski jumping • In Hinzenbach, Austria, Daniela Iraschko, of Austria, won her second straight women's World Cup ski jump event. The world champion, who also placed first in a shortened event Saturday, earned 238.4 points to beat World Cup leader Sarah Hendrickson, of Park City, by 5.2 points. Park City's Lindsey Van took third, eight points behind Iraschko.
Hendrickson leads the standings with 589 points, followed by Iraschko with 473 and Van with 302 points.
