events on the first day of competition but fell off the balance beam and ended the night in eleventh place. On the second night, she performed cleanly and ended up finishing in tenth place but won silver on the balance beam behind Simone Biles. As a result, she was added to the national team. In September, Eaker competed at the US World Championships trials, where she placed third in the all-around behind Simone Biles and Sunisa Lee. She also placed third on bars behind Lee and Leanne Wong, first on beam, and third on floor behind Biles and Lee. 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. 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. This decrease was due to her switch ring leap being downgraded to a switch split leap. 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. Her updated score instead placed her as the first reserve for the beam final. 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
