Career

Juniors

Sun represented Switzerland as a junior, finishing runner-up with Violet Apisah in the 2018 Australian Open girls' doubles, but also played under the New Zealand flag at junior Wimbledon that year, losing in the second round in singles and the first round in doubles.

2022: Professional and WTA Tour debuts

Before turning pro in 2022, Sun played college tennis at the University of Texas at Austin. In 2021, she competed in the NCAA DI women’s tennis championship for UT Austin, clinching the match and winning the 3rd ever NCAA championship.

She won her first big ITF title at the Saint-Gaudens Open, partnering Fernanda Contreras in doubles.

She made her WTA Tour main-draw debut at the Morocco Open just two days later, where she received a wildcard into the singles draw.

2024: Major, Masters debuts and first win

Sun made her major debut at the 2024 Australian Open. On her WTA 1000 debut, she recorded her first win at the WTA 1000 level at the 2024 Dubai Tennis Championships as a wildcard following the retirement of Paula Badosa. As a result, she moved to a new career-high singles ranking of No. 151, on 26 February 2024.

In April, Sun played under the New Zealand flag for the first time as part of the team for the 2024 Billie Jean King Cup.

In May, Sun won the singles and doubles titles at the W100 Bonita Springs tournament in Florida.

Personal life

Sun was born in New Zealand, then moved to Switzerland at the age of 5. She attended college in the United States at the University of Texas in Austin, graduating in 2022 with a BA in Political Science.

She has an older sister Phenomena Radovcic (born in 1998) who played in professional tournaments until 2016.
