The 18-yr old from Odessa, Ukraine, defeated Fanny Stollar, Zheng Saisai, Kristina Kucova, and Zhang Shuai, without dropping a set, to reach her first final on the WTA Tour. She dispatched sixth seed Wang Qiang, 6–2, 6–1 to lift her first trophy.

Wimbledon junior runner-up in 2015 (l. to Anastasia Potapova), she is coached by Olivier Jeunehomme, from the Justine Henin Academy.
