Jelena Ostapenko, born on June 8, 1997, in Riga, Latvia, is a professional tennis player known for her powerful, aggressive baseline game and her status as one of the sport’s most unpredictable talents. Multilingual, she speaks Latvian, Russian, and English[1]. Introduced to tennis at age five by her mother, she began focusing seriously on the sport around age 12 and quickly distinguished herself in the junior ranks, winning the Wimbledon girls’ singles title in 2014[1][3]. She turned professional in 2012[1][3][6]. Ostapenko’s breakthrough came in 2017, when, as a 20-year-old ranked outside the top 40, she captured the French Open singles title—her first Grand Slam and WTA title—by defeating Simona Halep in the final[1][3][5]. This victory made her the first unseeded woman to win Roland Garros since 1933 and the first Latvian to claim a Grand Slam singles title[1][5]. Her fearless, attacking style—evidenced by 50 winners in that final—catapulted her into the global spotlight[5]. She reached a career-high singles ranking of world No. 5 and has won nine WTA singles titles, including notable victories at Birmingham (2023), Dubai (2022, 2025), Linz (2024), and Stuttgart (2025)[2][5]. Ostapenko is also a formidable doubles player, with 11 WTA doubles titles and a career-high doubles ranking of No. 3. She claimed her first Grand Slam doubles title at the 2024 US Open with Lyudmyla Kichenok, adding to previous successes in events like Eastbourne and Brisbane[1][2][4]. In addition to her major titles, she has reached the semifinals at Wimbledon (2018) and the quarterfinals at the US Open (2023)[1]. As of October 2025, Ostapenko remains a fixture in the upper echelons of women’s tennis, with her 2025 Stuttgart Open triumph—defeating both world No. 2 Iga Swiatek and world No. 1 Aryna Sabalenka—underscoring her ability to compete with the very best[5]. Despite occasional inconsistency, her explosive game and Grand Slam pedigree ensure she is a constant threat at major tournaments and a prominent figure in Latvian sports[5]. Ostapenko continues to represent Latvia in team competitions and maintains a strong presence on the WTA Tour, both in singles and doubles[4].
