TOKYO (AP) — Mykayla Skinner won a silver medal on vault in the women's gymnastics event final to fulfil a lifelong Olympic dream. But she wasn't supposed to be there. She had the fourth-highest score during qualifications. But the rules allow each country a maximum of two athletes in the finals. Simone Biles and Jade Carey finished first and second to push Skinner from the competition. She was preparing to get on a plane to go home when Biles struggled at team finals last week. Skinner subbed in for her and now she's heading home with a silver medal.
