Daria Kasatkina Bio
Daria Sergeyevna Kasatkina is a Russian-born Australian professional tennis player who competes on the Women’s Tennis Association (WTA) Tour. She has been ranked as high as world No. 8 in singles, a position she first reached in October 2022, and she has won eight WTA Tour singles titles along with one doubles title. Her best Grand Slam results include a semifinal at the 2022 French Open and a quarterfinal at the 2018 Wimbledon Championships.
Born in Tolyatti, Russia, Kasatkina is known for a crafty, tactical style built on speed and shot variety rather than raw power. She came out as lesbian in 2022, publicly condemned the Russian invasion of Ukraine, and in 2025 switched her sporting nationality to Australia, becoming the country’s top-ranked women’s singles player.
Daria Kasatkina Early Life and Background
Daria Sergeyevna Kasatkina was born on 7 May 1997 in Tolyatti, Samara Oblast, an industrial city located about 1,000 kilometers southeast of Moscow. She is the daughter of Sergey Igorevich Kasatkin, an engineer at the Volga Automotive Plant, and Tatyana Borisovna Kasatkina, née Timkovskaya, a former lawyer. Both parents were nationally ranked athletes in Russia as Candidates for Master of Sports, with her mother competing in athletics and her father in ice hockey.
Kasatkina has an older brother, Alexandr, whose casual interest in tennis led her parents to enroll her in the sport at age six. She initially trained two to three times a week for two years before moving into higher-level competition. As her career costs grew, her parents made the difficult decision to sell their family home when she was about 12 to help fund her development. Her childhood friends from the Russian junior circuit include fellow top players Andrey Rublev and Alexander Bublik.
Path to Tennis
Kasatkina began competing on the ITF Junior Circuit shortly after turning 14 and quickly rose through the junior ranks, reaching as high as No. 3 in the world. She won the European 16s championship and, in 2014, captured the girls’ singles title at the French Open junior event, defeating top seed Ivana Jorović in the final. She was the first Russian girl to win the event since Nadia Petrova in 1998.
That same year, Kasatkina also represented Russia at the Youth Olympic Games in Nanjing, where she earned a silver medal in doubles alongside Anastasiya Komardina. These junior achievements helped her transition smoothly into the professional ranks, and she was coached by Maxim Prasolov from age 11 before later working with Damir Nurgaliev and then Vladimír Pláteník at the Empire Tennis Academy in Trnava, Slovakia.
Daria Kasatkina Career
Early Career (2014–2016)

In 2015, she climbed from No. 354 in the world to No. 72 by year’s end, winning four $25,000 ITF titles and reaching the third round of the US Open as a lucky loser. She also won her first WTA title in doubles at the 2015 Kremlin Cup, partnering Elena Vesnina.
In 2016, Kasatkina recorded her first career top-ten victory against world No. 7 Venus Williams at the Auckland Open and reached No. 24 in the WTA rankings. She also represented Russia at the Rio Olympics, where she reached the quarterfinals in both singles and doubles. Her doubles partnership with Vesnina notably defeated Martina Hingis and Sania Mirza, ending their 41-match winning streak.
WTA Tour Breakthrough (2017–2018)
Kasatkina won her first WTA singles title at the 2017 Charleston Open, defeating Jeļena Ostapenko in the final just before turning 20.

In 2018, Kasatkina reached the final of the Dubai Championships, defeating world No. 1 Caroline Wozniacki and world No. 3 Garbiñe Muguruza before losing to Elina Svitolina.

She won her second WTA title at the Kremlin Cup later that year, becoming Russia’s No. 1 player and finishing the season ranked No. 10 in the world.
Top Ten and Grand Slam Semifinal (2019–2022)
After a difficult 2019 in which her ranking dropped to No. 70, Kasatkina split with longtime coach Philippe Dehaes. She bounced back strongly in 2021, winning two WTA titles including the St. Petersburg Ladies’ Trophy, and returned to the top 30. In 2022, she captured her sixth title at the Silicon Valley Classic to return to the top 10 and was later runner-up at the 2020–21 Billie Jean King Cup Finals.
At the 2022 French Open, Kasatkina reached her first Grand Slam semifinal, defeating compatriot Veronika Kudermetova before losing to world No. 1 Iga Świątek.

Later that year, she declined an invitation to compete at the Paris Olympics as an Individual Neutral Athlete.

Driving Style and Strengths
Kasatkina plays a crafty baseline game that emphasizes variety, placement, and tennis intelligence over sheer power. She uses heavy topspin forehands, one-handed slice backhands, kick serves, drop shots, and tweeners to disrupt her opponents’ rhythm.

Her switch to represent Australia in 2025 marked a historic change, as she became the country’s new top-ranked women’s singles player.
