In February, Eaker was named to the team to compete at the 2019 International Gymnix in Montreal alongside Alyona Shchennikova, Sloane Blakely, and Aleah Finnegan.^[17] While there, she won gold in the team final, individual all-around, and on balance beam and placed fifth in the uneven bar final.^[18]

In June, after the conclusion of the American Classic, Eaker was named as one of the eight athletes being considered for the team to compete at the 2019 Pan American Games along with Sloane Blakely, Aleah Finnegan, Morgan Hurd, Shilese Jones, Sunisa Lee, Riley McCusker, and Leanne Wong.^[19]

At the 2019 GK US Classic, Eaker placed fourth in the all-around behind Simone Biles, McCusker, and Grace McCallum. She also placed first on balance beam and fourth on floor exercise behind Biles, McCallum, and Jade Carey. After the competition, she was named to the team to compete at the Pan American Games alongside Finnegan, Hurd, McCusker, and Wong.^[20]

At the Pan American Games Eaker competed on all four events, contributing scores on vault, balance beam, and floor exercise towards the team's gold-medal-winning performance. Individually, Eaker qualified for the balance beam final in first and for the all-around and floor exercise finals in second, both behind McCusker. She placed sixth on uneven bars but did not advance to the final due to teammates McCusker and Wong scoring higher.^[21][22] During the all-around final, Eaker placed fourth behind Ellie Black of Canada, McCusker, and Flávia Saraiva of Brazil due to falls on both the balance beam and floor exercise.^[23] During event finals, Eaker won gold on balance beam with a score of 15.266, finishing 1.7 points ahead of Black, who won the silver,^[24] and won silver on floor exercise behind Brooklyn Moors of Canada and ahead of Saraiva.^[25]

The following day, she was named to the team to compete at the 2019 World Championships in Stuttgart alongside Biles, Lee, MyKayla Skinner, Jade Carey, and Grace McCallum.^[28]

During qualifications at the World Championships, Eaker competed on bars and beam only, helping the USA qualify to the team final in first place over five points ahead of second place China. Eaker originally qualified to the balance beam final in fourth place; however, since her credited difficulty score (5.8) was nearly a point lower than her previous international performances - such as the 6.6 difficulty score she received at the Pan American Games - USA Gymnastics filed an inquiry in an attempt to raise her score.^[29] This decrease was due to her switch ring leap being downgraded to a switch split leap.^[30] While reviewing the routine, rather than crediting the leap, the judging panel instead downgraded a second dance element (her ring leap was credited as a split leap), lowering her score by an additional 0.4 points.^[31] Her updated score instead placed her as the first reserve for the beam final.^[32][33]

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.^[34] 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.^[35] 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.^[36] 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.^[37]

2023–2024 season

On October 20, 2023, Eaker, who was 20 years of age, announced via Instagram her retirement from the sport of gymnastics and her withdrawal as a student from the University of Utah, where she had been coached by Tom Farden, citing verbal and emotional abuse from a coach and lack of support from the administration.^[46][47] In her Instagram post she states that she had been diagnosed with severe anxiety and depression, anxiety induced insomnia, and suffers from panic attacks, PTSD, and night terrors.^[48][49] Eaker cited that the abuse often happened in individual coach-athlete meetings, in which she would be isolated in a closed-door office with an overpowering coach, while he used "condescending, sarcastic and manipulative" tactics. Additionally she states that she was "personally attacked, humiliated, degraded and yelled at to the point of tears in front of the whole team". Furthermore, Eaker stated that the University of Utah administration "completely dismissed" her when she attempted to report the abuse.^[50]

A second student made a similar complaint four days later, and in early November Farden was put on administrative leave by the school.^[46] Nine days later Farden was officially removed from his coaching position.^[51]
