Professional career

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.^{[citation needed]} She made her WTA Tour debut at the same tournament one year later, after having been handed a wildcard 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]
