Katerina Siniakova’s doubles ranking record now puts her level with a living legend.
The 29-year-old Siniakova has secured the WTA Year-End Doubles No.1 Ranking presented by PIF, earning the accolade for the fifth time in her career.
To celebrate Siniakova’s incredible 2025 season, the Czech was honored during a special presentation at the WTA Finals Riyadh presented by PIF earlier today where she officially received the year-end No.1 trophy.
Siniakova previously ended the season in the elite ranking position in 2018 (when co-ranked No.1 with Barbora Krejcíkova), 2021, 2022, and 2024, now tied with Czech-born Martina Navratilova, each recording five seasons for the most No.1 doubles year-end finishes in WTA history.
This wasn’t her only history-making achievement this season, as the week of November 10, 2025 will mark Siniakova’s 169th week holding the No.1 position – now the third-most weeks in WTA history, behind only Liezel Huber (199) and Navratilova (237).
“It feels very special, it’s amazing for me and I’m just so happy I’ve done it again,” said Siniakova. “There’s been so many great memories this season and I’m just so grateful I can lift this trophy again.”
Siniakova’s 2025 season has been defined by excellence and versatility across multiple team partnerships. She captured four titles, beginning with the Australian Open and the WTA 1000 Dubai Duty Free Tennis Championships, both alongside Taylor Townsend. She later claimed another WTA 1000 crown at the Dongfeng · Voyah Wuhan Open with Storm Hunter, and added a WTA 500 title at the Korea Open Tennis Championships with long-time partner Barbora Krejcikova.
