Early Career
Born in Xi’an, China, Zheng Saisai began playing tennis at the age of eight. Unlike many modern players who rely on pure power, Zheng developed a crafty game centered on sliced forehands, drop shots, and exceptional court coverage. She turned professional in 2008 and quickly made her mark on the ITF circuit.
Her transition to the main tour gained momentum in 2011 when she won her first WTA doubles title in Guangzhou alongside Hsieh Su-wei.
This early success in doubles laid the foundation for her career, teaching her the net skills and tactical awareness that would become hallmarks of her singles game.
She steadily climbed the rankings, breaking into the top 100 and representing China in the Fed Cup (now Billie Jean King Cup) with pride.
Professional Career
Zheng Saisai’s professional journey is a testament to resilience. Her career reached a high point in 2019 when she won her maiden WTA singles title at the Premier-level Silicon Valley Classic in San Jose, defeating top players like Aryna Sabalenka.
This victory propelled her to a career-high singles ranking of No. 34 in 2020. In doubles, she has been even more prolific, reaching the final of the 2019 French Open and achieving a career-high ranking of No. 15.
However, her career has been interrupted by significant injuries, particularly a severe wrist injury that kept her sidelined for nearly two years (2022-2023). She made a courageous comeback in 2024 using a protected ranking.
In the 2025 season, Zheng has continued to compete, focusing heavily on doubles where her tactical nous remains elite, while carefully managing her singles schedule to preserve her body.
She remains a respected veteran on tour, serving on the Player Executive Committee of the Professional Tennis Players Association (PTPA).
Coach
Throughout her career, Zheng Saisai has worked with various coaches to refine her unique game. In the past, she was coached by Alan Ma and later worked with her mother, who played a significant role in her early development.
For the 2025 season, specific details about her primary traveling coach have not been publicly disclosed in major tennis directories.
Given her veteran status, she likely works with a collaborative team or a pool of coaches associated with the Chinese national setup or private academies, tailoring her training to manage her physical workload post-injury.
