Early Life and Relocation to Serbia

Sun began playing tennis at the age of five in her hometown of Shenzhen, China. Her natural talent and athleticism quickly set her apart from her peers.

By the time she was 10 years old in 2020, her family and management team realized she needed a more rigorous, globally competitive training environment. They orchestrated a long-term relocation to Belgrade, Serbia. This move placed her closer to elite European academies, specialized clay-court training, and the highly competitive European junior circuit.

Junior Grand Slam Success (2026)

The 2026 season served as Sun’s definitive breakout year. In June, she reached the No. 1 spot in the ITF Junior combined world rankings.

Her dominance on the junior circuit culminated in deep runs across three major surfaces. She reached the finals at both the French Open (clay) and Wimbledon (grass). At Wimbledon, she suffered a hard-fought, three-set loss to her primary junior rival, Anna Pushkareva.

However, Sun found her redemption on the hard courts of New York. During the 2026 US Open in September, she faced Pushkareva again in the girls’ singles final. Sun defeated her rival in a rollercoaster three-set match (6-4, 4-6, 6-0) to claim her first Junior Grand Slam championship.

WTA Tour Debut and the 2026 China Open

Following her US Open triumph, organizers awarded Sun a wildcard entry into the main draw of the 2026 China Open in Beijing. The event marked her official debut on the senior WTA Tour.

The 16-year-old immediately proved she belonged at the professional level. In the second round, Sun staged an impressive comeback against the No. 27 seed, Cristina Bucsa. After falling behind a break in the second set, Sun rallied to win 6-4, 7-5.

The upset marked a series of professional milestones for Sun. It was her first career Top 50 victory, and she became the first player born in 2010 to reach the third round of a WTA 1000 event. The win also set up a highly anticipated Round of 32 clash with No. 3 seed Coco Gauff.

Playing Style and Professional Titles

Sun plays right-handed and relies on a powerful two-handed backhand. While she has proven her adaptability by reaching the finals of the French Open and Wimbledon juniors, she actively lists hard courts as her preferred playing surface.

Outside of her main tour debut, she has already begun accumulating hardware on the lower-level professional circuit. In late 2025, she secured two W15 singles titles in Sharm El Sheikh, Egypt. As of late 2026, her highest career WTA singles ranking is No. 599.
