In October, Biles participated in the World Team Selection Camp. She placed first in the all-around as well as first on vault and floor exercise. She placed second on the uneven bars behind McCusker, and fourth on balance beam (due to hands touching the mat on dismount) behind Kara Eaker, McCusker, and Ragan Smith. Biles debuted a new vault: a Yurchenko with a half turn on with a stretched salto forward with two turns (Cheng with an extra half twist). The following day she was named to the team to compete at the 2018 World Championships alongside McCusker, Hurd, Grace McCallum, Eaker, and alternate Ragan Smith.
