Nagasu has worked on improving her jumps to avoid under-rotations. She has added a triple Axel jump to her programs, landing two fully rotated triple Axel jumps at the 2017 CS U.S. International Figure Skating Classic with the negative grade of execution. She is the second US woman skater to have landed a triple Axel jump internationally after Tonya Harding. In 2018, she became the first U.S. woman skater to have landed the triple Axel in an Olympic competition.
