Her most significant junior achievement came at the 2016 US Open, where she won the girls’ singles title, defeating Viktória Kužmová in the final.

Professional Beginnings and Early Success (2016-2017)
Day turned professional in 2017, making her Grand Slam debut at the Australian Open that year. Even before officially turning pro, she made her mark on the WTA Tour. In 2016, after winning the USTA Girls’ 18s National Championships to earn a wildcard into the main draw of the US Open, she defeated Madison Brengle in the first round. Shortly after her 17th birthday, she won her first professional title at a $50,000 ITF tournament in Macon, Georgia. One of her most impressive early career performances came at the 2017 Indian Wells Open, a Premier Mandatory event. As a wildcard, she defeated 2017 Australian Open semifinalist Mirjana Lučić-Baroni to reach the third round, where she played a hard-fought three-set match against future Grand Slam champion Garbiñe Muguruza.
Struggles with Injuries and Illness
Following her promising start, Day’s career was significantly hampered by a series of debilitating injuries and health issues. For several years, she faced a relentless string of physical setbacks that kept her off the court for extended periods. The list of ailments was extensive and included a torn quad, a fractured foot, torn labrums in both hips, and a bout of mononucleosis, which left her feeling unwell for a long time. This period of adversity was not only physically challenging but also mentally taxing, as her ranking plummeted and she had to watch her junior contemporaries achieve success on the main tour. Just as she was starting to feel healthy again, the COVID-19 pandemic hit, further complicating her return to competitive tennis.
The Comeback Trail
Despite the numerous obstacles, Day’s determination never wavered. She embarked on a grueling comeback, primarily competing on the ITF Women’s World Tennis Tour to rebuild her ranking.

After successfully navigating the qualifying rounds, she made her first Grand Slam main draw appearance since the 2017 US Open. She went on to defeat Kristina Mladenovic and then scored a career-best win over the 20th seed, Madison Keys, to reach the third round of a major for the first time. This impressive run helped her break into the top 100 of the WTA rankings for the first time in July 2023. She continued her strong form by winning two ITF W100 titles in 2023. In April 2024, she achieved a career-high singles ranking of world No. 84.
