>> The United States four foot nine dynamo Simone Biles showed the world who's on top, vaulting her way to her first individual Olympic gold in the women's all-around competition. Teammate Aly Raisman took silver and Russian gymnast Aliya Mustafina bronze, just edging out China's Shang Chunsong. But first place for the sport's top athlete wasn't always a sure thing.
Mustafina briefly took the lead after Biles' performance on the uneven bars. The slightly rattled American though showed why she's a three-time world champion. And ended her day with a smashing floor routine that earned a 15.9, the highest score of the day. Alexandra was there.>> I was at Simone's first Olympic appearance on Sunday, and she was all smiles, grinning from ear to ear, waving at the audience the whole time, kind of her giggly 19-year-old self.
Tonight she was much more serious. She didn't smile as much. She was very focused, talked a lot with her coach. And then she won and once she won and climbed onto the podium and started crying, and it all kind of came out. And she told us afterwards, she had so many emotions and feelings running through her head, mostly I've done it.
>> This is Biles' second medal of the games. Earlier this week, she helped the US defend their 2012 team gold. And the 19 year old could still pick up three more before the competition's over. Biles joins the ranks of Mary Lou Retton, Carly Patterson, Nastia Liukin, and Gabby Douglas as American all-around winners.
