Katerina Siniakova Ties Martina, Claiming Fifth WTA Year-End No.1 Doubles Ranking

Katerina Siniakova has secured the WTA Year-End Doubles No.1 Ranking, earning the honor for the fifth time in her career.

The the-time major doubles champion  was honored during a special presentation at the WTA Finals on Wednesday. 

Siniakova is, now tied with Martina Navratilova, with each doubles icon recording five seasons for the most No.1 doubles year-end finishes in WTA history. The 29-year-old Czech previously ended the season No.1 in 2018 (when co-ranked No.1 with Barbora Krejcíkova), 2021, 2022, and 2024. 

She is one of only 12 players to have ever held the WTA’s year-end No.1 ranking more than once.

She has held the WTA’s No.1 doubles ranking for a total of 168 weeks, which is third most all-time, behind only Leizel Huber (199) and Martina Navratilova (237). 

Siniakova, a former world No.27 in singles, also has two Olympic gold medals –  one in mixed (2024 Paris), one in doubles (2020 Tokyo) – and a mixed doubles Grand Slam title (2025 Wimbledon) to her name.
