The qualifications also served as a team and individual AA qualifier for the 2020 Olympics. Former UCLA standout Danusia Francis qualified as an AAer. Update: The FIG has thus far confirmed 20 women in the AA. They will name more after the event finals, with Simona Castro of Chile (ex DU) and Ariana Orrego of Peru (Iowa State) in position.
Besides the US, China and Russia, who had previously qualified, France, Canada, the Netherlands, Great Britain, Italy, Germany, Belgium, Japan and Spain made the cut. There are additional methods of qualifying extending into 2020, including the World Cup series and the Continental Championships. The biggest surprise in the prelims was that Brazil failed to make the cut, with injuries to key athletes, including at the meet itself.
