Czech tennis star Katerina Siniakova has created history by securing her sixth year-end World No. 1 finish in women’s doubles on the WTA Tour. The achievement makes her the most successful player in the history of the year-end doubles ranking, surpassing the previous record held by tennis legend Martina Navratilova.
The Women’s Tennis Association confirmed the milestone on November 13, 2026, during the ongoing FAGE WTA Finals in Indian Wells, California. Siniakova’s outstanding performances throughout the season helped her secure the top position once again.
A Record-Breaking Season for Siniakova
Siniakova has enjoyed an exceptional 2026 campaign, collecting seven doubles titles across the season. Five of those victories came alongside American partner Taylor Townsend, while two were secured with China’s Zhang Shuai.
Her achievements include major victories at the French Open and US Open, along with four WTA 1000 tournament titles. These results have established her as one of the most dominant doubles players on the women’s circuit.
She also reached nine finals in 15 tournaments and recorded an impressive 54 wins against eight losses during the season.
Surpasses Martina Navratilova’s Record
The Czech star’s sixth year-end No. 1 finish places her ahead of Martina Navratilova, who previously held the record with five such finishes.
Siniakova has also spent 209 weeks at the top of the WTA doubles rankings, making her second on the all-time list for total weeks at No. 1. Navratilova remains ahead with 237 weeks.
The latest milestone further strengthens Siniakova’s position among the greatest doubles players in women’s tennis history.
Historic Partnership With Taylor Townsend
Siniakova and Taylor Townsend have formed one of the most successful doubles partnerships of the 2026 season. Their victories at Roland-Garros and the US Open were among the highlights of their campaign.
Their US Open triumph was particularly significant because it helped Siniakova become the first player in the Open Era to complete a career Grand Slam in women’s doubles with two different partners. She had previously achieved the feat with compatriot Barbora Krejcikova.
The partnership with Townsend has also produced several important WTA tournament victories and helped both players maintain their positions among the world’s leading doubles competitors.
Siniakova Continues Her WTA Finals Campaign
Despite securing the year-end No. 1 ranking, Siniakova is still competing for another major title at the FAGE WTA Finals in Indian Wells alongside Townsend.
The pair have reached the semifinals for the third consecutive year. Their latest campaign gives them another opportunity to finish the season with a prestigious championship victory.
Siniakova’s consistent performances throughout 2026 demonstrate why she remains a formidable presence in women’s doubles.
A Remarkable Legacy in Women’s Tennis
At 30, Siniakova has already built an impressive career, collecting 12 women’s doubles Grand Slam titles and two Olympic gold medals across women’s and mixed doubles.
Her latest achievement reflects years of consistency, adaptability and success with different partners. By securing a record sixth year-end No. 1 finish, she has set a new benchmark for future generations of doubles players.
