Vonn iced the overall title with her year's best showing in the slalom. She was 25th after the first run and jumped up to 11th with the best second run of the day. She only needed to be in the top 15 to close out Maria Riesch, who was the only skier who could catch Vonn in the overall standings.
Marlies Schild won the slalom with a two-run total time of 1 minute, 52.78 seconds, just ahead of Veronika Zuzulova, who was clocked at 1:52.85. That allowed Schlid to win the season's slalom championship.
Vonn's total time was 1:54.93, but it was her second-run time of 59.70 that put the overall title away.
Vonn is the first U.S. woman to take the overall title since Tamara McKinney did so in 1983
Bode Miller won the men's overall. It is the first time U.S. skiers won both the men's and women's crowns sinced Phil Mahre and McKinney were champions in 1983.
