In February, Kozlova reached her first WTA Tour final at the Taiwan Open, defeating Sabine Lisicki in the semifinals, before losing the championship match to Timea Babos.
At the French Open in May, she became the second player to defeat a defending champion in the first round of the French Open, after a straight sets victory over 2017 champion Jeļena Ostapenko.

### 2022: Poland Open semifinal

Having lost in qualifying, Baindl gained entry to the Poland Open as a lucky loser where wins over 11th seed Maryna Zanevska, qualifier Sara Errani and eighth seed Petra Martić, saw her reach the semifinals. She lost to Ana Bogdan in the last four.
At the Emilia-Romagna Open in Parma, she qualified into the main draw where she was defeated by world No. 7 and top seed, Maria Sakkari.

### 2023-2024: Australian Open third round
