In the team final, Eaker competed a hit routine on balance beam and did not attempt the switch ring leap, helping the USA win the gold medal ahead of Russia and Italy. She tied with Chen Yile of China for the third highest beam score in the final behind teammate Biles and first-year Chinese competitor Li Shijia. During the all-around final, Canadian Ellie Black, who qualified in seventh place to the balance beam final, was injured on vault. She later pulled out of the balance beam final, allowing Eaker to replace her as first reserve. During the balance beam final, Eaker once again performed a clean routine without her switch ring leap and scored 14.000, finishing fourth behind 2014 and 2015 World balance beam champion Biles, reigning World balance beam Champion Liu Tingting, and Li.
