Make it a pair of golds for Gabby Douglas, who added the all-around title to the one she won with the U.S. team two nights ago.
Douglas became the third straight American to win gymnastics' biggest prize, taking the lead on the very first event Thursday night and never really letting anyone else get close. She finished with a score of 62.232, less than three-tenths ahead of Viktoria Komova of Russia.
Aly Raisman of the United States finished fourth.
Douglas brought the house down with her energetic floor routine, and U.S. teammates Jordyn Wieber, McKayla Maroney and Kyla Ross jumped to their feet and cheered when she finished. Douglas flashed a smile and coach Liang Chow lifted her off the podium.
