"I skied aggressively and that's exactly what I wanted to do, not only for today, but also to give me confidence going into Vancouver," Vonn said.

With 440 points to 220 for Swiss Fabienne Suter, the two-time defending overall champion assumes an insurmountable lead in the discipline with only two events remaining on the World Cup calendar post Olympics.

"It's nice to have it out of the way," said U.S. Women's Head Coach Jim Tracy. "None of us gave that any thought whatsoever today. Lindsey didn't even realize it. Still, it's nice to get a crystal globe at the end of January."

A bigger motivation for Vonn was missing the podium in downhill for the first time in seven straight tries Saturday, when a late mistake cost her time and she took fifth.

"It goes back to the last race a bit," Tracy said. "She was a little disappointed, she could have won if it wasn't for that bobble, so she came out today and let her rip."

"I think I bounced back pretty strong," Vonn said. "I just stayed positive. I didn't give up and I fought hard."

Vonn's ninth win of the season ties her own American record and leaves her one short of Bode Miller's still-active mark for most wins by a U.S. skier (32). Vonn also expanded her overall lead to 137 points over Germany's Maria Riesch.

The women's team will arrive in Vancouver Feb. 9 with the opening event on Sunday, Feb. 14 with the Olympic super combined.
