Yeo won the gold medal on vault at the Melbourne World Cup. According to the Korea Gymnastics Association, it was the first time that a Korean female gymnast won a gold medal in the FIG World Cup series.[7] At the 2019 Korea Cup, Yeo became the first woman to land the handspring double twist vault. She said of the new vault, "I was afraid, but once I started focusing on the competition, my fear disappeared. I am so happy that I was able to execute that. I wanted to land the new vault regardless of my final rankings today, and everything went my way."[8] In the 2019 World Championships in Stuttgart, Yeo qualified to the vault final in 5th place with a score of 14.766, and finished last in the final after a fall and going out of bounds when attempting the handspring double twist vault.
