Katerina Siniaková: Meet the Czech tennis star, her age, height, rankings, prize money and more

Katerina Siniakova is one of the most decorated doubles players women's tennis has ever seen. The Czech star, now 30, holds the world No. 1 doubles ranking, has won 10 Grand Slam doubles titles, completed the Career Golden Slam, and made history at two consecutive Olympics. She recently reclaimed the top spot after winning Madrid alongside Taylor Townsend, adding another chapter to a career that refuses to plateau.

How old is Katerina Siniakova and where did she come from?

Born on May 10, 1996, in Hradec Kralove, Czech Republic, Katerina Siniakova turned professional in 2012 and has been a fixture on tour ever since. She grew up in a sports-driven household. Her father, Dmitri Siniakov, came from Russia and had a background in boxing. Her mother, Hana, works as an accountant. Her younger brother Daniel also played tennis, which meant the family home had a genuinely competitive edge rather than just casual support from the sidelines.

She picked up a racket at five years old and rose quickly through junior ranks, developing the all-court game that still defines her today.

How tall is Katerina Siniakova and how does it shape her game?

Siniakova stands 5 feet 9 inches tall, or 1.74 meters. That frame gives her natural reach at the net, which matters enormously in doubles, where positioning and first-volley instincts often decide points faster than any groundstroke rally can.

Her game is not built around power. Instead, she relies on anticipation, quick hands, and the ability to cover court efficiently from both the baseline and up close. It is a style that ages well, and her results at 30 prove that.

Who coaches Katerina Siniakova?

Her current coaching setup involves Peter Huber as her lead coach, with her father Dmitri serving as a consistent presence throughout her career. She previously worked with former Russian player Evgeniia Maniukova, but the combination of professional guidance and family continuity has remained a defining feature of how she operates.

What is Katerina Siniakova's current ranking?

As of May 2026, Siniakova sits at world No. 1 in doubles and No. 36 in singles. Her career-high singles ranking reached No. 27 in June 2024. In doubles, she has now spent more than 180 weeks at the top of the world rankings, one of the longest cumulative runs in WTA history.

What are Katerina Siniakova's career earnings and biggest achievements?

Katerina Siniakova has crossed $16.1 million in career prize money, with more than $2 million earned in the 2025 season alone. The financial numbers reflect the depth of her success, but the trophies tell the fuller story.

She has won 10 Grand Slam doubles titles across all four majors, most of them alongside Barbora Krejcikova, with whom she formed arguably the most successful Czech doubles partnership in modern tennis. After winning Olympic gold at Tokyo in women's doubles and then adding mixed doubles gold at Paris with Tomas Machac, she became the first player in Open Era history to claim Olympic gold in both disciplines, a distinction recognised by Guinness World Records. She has also lifted Grand Slam titles with Coco Gauff and Taylor Townsend, showing a rare adaptability that most top doubles players never develop.

Her tally stands at more than 35 WTA doubles titles and five WTA singles crowns, with victories at events including Indian Wells, Miami, Madrid, and Dubai.
