American Lindsey Vonn extended her dominance at Lake Louise Friday, winning the first of two women\'s World Cup downhills slated for the Canadian resort. In a race disrupted by fog, Vonn clocked 1min 52.61sec to win her 27th World Cup downhill and her 12th at this venue in the Canadian Rockies. American Stacey Cook was a distant second, 1.73sec back with Germany\'s Maria Hoefl-Riesch and Liechtenstein\'s Tina Weirather sharing third, 1.74sec behind Vonn. The race was halted for an hour and a half because of poor visiblity after the run of starter number 25, Austrian Anna Fenninger. Vonn was already in the lead by then. The 28-year-old American, who landed in the hospital earlier this month with a painful intestinal illness, looked quite like her normal self a week after she was clearly exhausted after competing in a giant slalom in Colorado. Slovenia\'s Tina Maze, who seized the World Cup overall lead with two giant slalom victories already this season, settled for 20th place.
