Nikola Bartunkova is the latest graduate of the Czech production line, a Prague-born 2006 talent who trains at her home club CLTK Stvanice with the support of her father and her coach. She turned pro in 2020, built a junior résumé headlined by a 2023 Wimbledon girls' singles final, and won her first tour-level match in October 2023, defeating Dayana Yastremska in the first round of the Transylvania Open before losing in three hours to Ana Bogdan.
The 6-foot Czech is a self-styled aggressor who doesn't sit on the baseline. She describes herself as a player who likes to attack, go to the net and vary her game, leaning on a strong backhand while reworking the forehand. The serve is a genuine weapon — she wins 68.2% of first-serve points, though roughly 0.54 double faults per game flags the volatility that comes with it.
The spine of her story is the interruption. In November 2024 she was handed a six-month ban backdated to April 2024 for testing positive for unintentional use of trimetazidine at two early-2024 events. She rebuilt from the ITF floor: her 2025 breakthrough came reaching the semifinals at WTA 500 Guadalajara, which lifted her into the top 200 for the first time. The senior arrival landed in Melbourne — a main-draw debut where she beat Daria Kasatkina, then upset Belinda Bencic for her first top-10 win, before Elise Mertens ended her run in the third round.
That form has carried into 2026. At the Italian Open she reached the round of 16, beating Madison Keys 6-3, 1-6, 6-4 before facing Elina Svitolina. Now at world No. 61, she's the rare player who out-sprinted a suspension into the heart of the rankings.
