The U.S. women, heavy favorites for the Olympic gold medal, scored 181.863 points early Sunday afternoon, then waited to see if Russia, Romania or China could match it.
Not even close.
Russia, runner-up to the Americans at last year's world championships, was 1.4 points back with a score of 180.429. Beijing Olympics champion China was third (176.637), followed by European champion Romania (176.264) and Britain (170.656). Japan, Italy and Canada rounded out the top eight.
The team final is Tuesday night.
While the Americans were on top, world champion Jordyn Wieber was not. In the biggest shocker of the day, the gold medal favorite failed to qualify for the all-around final after finishing behind U.S. teammates Aly Raisman and Gabby Douglas.
