Lulu Sun (born Lulu Radovcic; 14 April 2001) is a New Zealand and Swiss tennis player. She has a career-high singles ranking by the WTA of No. 123, achieved on 24 June 2024, and a best doubles ranking of No. 219, reached on 6 May 2024.

Early and personal life

Sun was born in New Zealand to a Croatian father and a Chinese mother. She was raised in Switzerland from the age of five, where she completed her school education. She attended college in the United States at the University of Texas at Austin, graduating in 2022 with a BA in Political Science.

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

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 in Austin. In 2021, she competed in the NCAA DI women’s tennis championship for UT Austin, clinching the match and winning the third NCAA championship for UT's women's tennis program.

In May 2022, 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, WTA 1000 debuts, historic Wimbledon quarterfinal, top 55

Sun made her Grand Slam debut at the 2024 Australian Open after qualifying. On her WTA 1000 debut, she recorded her first win at that level at the Dubai 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. She reached the top 125 on 17 June 2024.

She qualified for the 2024 Wimbledon Championships making her debut at this major and upset eighth seed Zheng Qinwen in the first round. It was her first top 10 win, and also her first completed victory over any player in the top 100. Next, she reached the third round with a win over fellow qualifier Yulia Starodubtseva and the fourth with a win over Zhu Lin. She equalled the feat of reaching the fourth round at the All England Club as the first New Zealand female player in the Open Era, and second after Dame Ruia Morrison in 1957 and 1959. She reached her first quarterfinal with a win over Emma Raducanu becoming the first New Zealand woman to ever reach that stage at Wimbledon in the Open Era. She was only the second woman from New Zealand to reach a Major quarterfinal, following Belinda Cordwell at the 1989 Australian Open. As a result, she climbed into the top 55, having moved 70 positions up in the WTA rankings. She will play Donna Vekić in the quarterfinals.
