Career

2021–24: WTA debut, 6 months 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 WTA 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: WTA 125 final & WTA Tour quarterfinal, Top 150

In January, Bartůňková played first matches after end of her hiatus in Oslo, reaching semifinal at W15 event where she lost to Anouck Vrancken Peeters.[12] 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.[13] In July, Bartůňková qualified for the 2025 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 into Guadalajara 125 Open, where she lost to eventual finalist Panna Udvardy in the second round.[14] The following week, she received another wildcard entry in Guadalajara, this time at the 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,[15] where she overcame defending champion Magdalena Fręch.[16] Her run was ended in the semifinals by eventual champion Iva Jovic in three sets.[17][18] As result she moved up 80 places in the rankings to enter the top-200 for the first time at world No. 144 on 15 September 2025.[19]

In October, Bartůňková reached her first WTA 125k final at Samsun Open but lost to 2nd seed Kaja Juvan.[20] Bartůňková received a wildcard to the WTA 500 in 2025 Toray Pan Pacific Open in Tokyo but lost to local wildcard Wakana Sonobe.[21] The following week she lost in the opening round in Chennai after losing to eventual finalist Kimberly Birrell in three sets.[22]

In November, Bartůňková received her first nomination for the national team in Billie Jean King Cup and helped her team to win Group D. Czech teenager beat Yuliana Lizarazo from Colombia, but lost to Petra Marčinko from Croatia.

2026: Grand Slam debut & first top 10 win

In January, Bartůňková entered her first Grand Slam qualification at the 2026 Australian Open as the 16th seed. She then scored three wins to make her main draw debut, where she defeated former top-10 player Daria Kasatkina for her first Grand Slam win.[23] Bartůňková reached the third round with an upset over Belinda Bencic, marking her first top-10 win.[24] Her run was ended in the third round by 21st seed Elise Mertens in straight sets.[25]
