A late run of form helped her qualify for the WTA Elite Trophy Zhuhai, and after the strong end to the season, Karolina Muchova earned your votes for the final Breakthrough of the Month award for 2019.

Muchova reached the semifinals of the Premier-level Kremlin Cup in Moscow, as she defeated Svetlana Kuznetsova and a pair of seeds, Ekaterina Alexandrova and Donna Vekic, before falling to Anastasia Pavlyuchenkova in a thrilling semifinal match.

The Wimbledon quarterfinalist booked the last spot in the WTA Elite Trophy Zhuhai on the back of that result, for her season-ending tournament debut, and won a pair of three-setters against Alison Riske and Sofia Kenin before falling to eventual champion Aryna Sabalenka in the semifinals.
