# Kateřina Siniaková career statistics

This is a list of the main career statistics of professional Czech tennis player Kateřina Siniaková.

Beside Grand Slam success, in doubles she also won the WTA Finals in 2021, four WTA 1000 titles (three Mandatory – the 2021 Madrid Open, 2023 Indian Wells and 2024 Dubai, and one non-Mandatory – the 2019 Canadian Open.
Despite having less success in singles, she still left her mark. Her most significant results are two quarterfinals at the China Open and Wuhan Open in 2018. At Grand Slam tournaments, she reached the round of 16 at the 2019 French Open, where she also defeated world No. 1, Naomi Osaka, to make her biggest win so far.
