Mancuso 8th on home course

ASPEN, Colo. (AP) - Too anxious, Lindsey Vonn skied too straight and right off the winding course.

On edge, Julia Mancuso conservatively completed her second run after nearly losing a ski up top.

That's the way the day went for the Americans on their home hill.

Vonn failed to finish her first run Saturday in the World Cup giant slalom, while Mancuso, in second place after a flawless opening performance, wound up eighth.

There was no such problems or predicaments for France's Tessa Worley as she used a strong second trip through the course to edge Olympic champion Viktoria Rebensburg of Germany by 0.01 seconds.

Mancuso, from Squaw Valley, Calif., was in prime position to earn a spot on the podium after a nearly flawless first run.

But her ski wobbled on her last trip through the course, causing her to ease off the accelerator. She's recently lost her ski twice in training.

"I don't know if something weird clicked in my head," said Mancuso, who won gold in the GS at the 2006 Turin Olympics. "I backed off a lot."
