Career
2021–24: WTA debut, anti-doping ban
In April 2021, at the 2021 İstanbul Cup, Bartůňková attempted her WTA Tour debut. She defeated world No. 152, Leonie Küng,[2] in the first round of qualifying, before losing to Anastasia Gasanova. She made her WTA Tour debut at the same tournament one year later, after being handed a wildcard entry for the main-draw, losing to Anastasia Potapova.[3]
On 16 October 2023, Bartůňková won her first Tour-level match when she defeated Dayana Yastremska in the first round of the 2023 Transylvania Open,[4][5] before losing in three hours to Ana Bogdan in the second round.[6][7]
In November 2024, Bartůňková was issued with a six-month competition ban backdated to April 2024 for an anti-doping rule violation after testing positive for unintentional use of trimetazidine (TMZ) at two events in early 2024.[8] She had been provisionally suspended from May 2024 until the conclusion of the investigation.[9][10] The International Tennis Integrity Agency (ITIA) accepted that the source of the TMZ was a contaminated supplement for which she bore "no significant fault or negligence" for having ingested.[11]
2025: Comeback, top 200-debut
Bartůňková played first matches after end of her hiatus in January in Oslo, reaching semifinal at W15 event where she lost to Anouck Vrancken Peeters.
At her second event at W35 in Sunderland, Bartůňková claimed her fourth career title. Bartůňková reached another final just week after at W35 event in Glasgow.
In July, Bartůňková qualified for Ladies Open Hechingen and beat two former top-100 players, María Lourdes Carlé and Julia Grabher, en route to her first W75 title.
In September, Bartůňková was awarded a wildcard entry into Guadalajara 125 Open, where she lost to eventual finalist Panna Udvardy in the second round. The next week, she received another wildcard entry in Guadalajara, this time at WTA 500 event Guadalajara Open Akron, and scored her second career WTA main-draw win over Nicole Fossa Huergo. She defeated fellow Czech player Darja Viďmanová in straight sets to reach her maiden WTA Tour quarterfinal, where she overcame defending champion Magdalena Fręch. Her run was ended in the semifinals by eventual champion Iva Jovic in three sets. As result she moved up 80 places in the rankings to enter the top-200 for the first time at world No. 144.
