Olga Danilović

Olga Danilović is a Serbian tennis player who became the first player born in the 2000s to win a WTA singles title, and reached the fourth round of two Grand Slams in 2024 and 2025.

As a 17-year-old lucky loser at the 2018 Moscow River Cup, Olga Danilovič won a three-set final over Anastasia Potapova to become the first player born in the 2000s to win a WTA Tour title — a record she held for years and which announced her as one of the most significant young prospects in European women's tennis. She started playing tennis at age six and made her Billie Jean King Cup debut for Serbia in February 2018, winning all three of her singles matches, including an upset of world No. 15 Anastasija Sevastova, and donating her prize money to a Belgrade children's hospital. Later in 2018, as a lucky loser at the Moscow River Cup, Danilović defeated fellow teenager Anastasia Potapova in a three-set final to win her first WTA singles title, becoming the first player born in the 2000s to win a WTA Tour title. She reached the world's top 100 that October at just 17, becoming the fourth-youngest player in the year-end top 150. Danilović added a second WTA singles title in Guangzhou in 2024, and enjoyed her best Grand Slam runs that year and the next, reaching the fourth round of the French Open in 2024 — beating Danielle Collins and Donna Vekic along the way — and the Australian Open in 2025, where she defeated Jessica Pegula before losing to Paula Badosa. She reached her career-high singles ranking of World No. 32 in July 2025, and continues to represent Serbia in the Billie Jean King Cup.
