On July 28 Bowers competed at the 2018 U.S. Classic. She finished third in the all-around behind Wong and DiCello after falling twice on floor exercise. She finished second on balance beam and uneven bars. Bowers traveled to Boston to compete in the 2018 U.S. Championships in August. She was one of the favorite to win the title based on her earlier victories in the all-around, but she struggled on the first day with multiple errors and finished in 17th place in the all-around on the first day. Bowers withdrew from the second day of competition, citing an injury sustained during training that had also hampered her on the first day of competition. Because she did not finish in the top six all-around, she was not automatically named to the national team.
