LENZERHEIDE, Switzerland (AP) — Lindsey Vonn won her sixth straight World Cup downhill title after thick fog forced the final race to be canceled Wednesday. Five weeks after her season was ended by a serious knee injury, Vonn retained her title by beating Tina Maze of Slovenia by one point. Fog hung on the lower slopes all day and earlier forced the International Ski Federation to cancel the men's downhill. The women's race was canceled at 2:30 p.m. (1330 GMT), three hours after its scheduled start.

In a strange twist, Vonn was denied a fourth straight overall title in 2011 by the weather in Lenzerheide.
