For Americans this has become the year of defending champions not performing to expectations. World-class gymnast Jordyn Wieber was edged out by her two teammates in the all-around performance, missing the finals by four-tenths of a point.
In 2011 Wieber defeated Russian super-gymnast Viktoria Komova in the all-around, making this Olympiad a much-anticipated rematch. Now the defending-champ will have to watch from the sidelines as her teammates advance on.
