Katerina Siniakova is the WTA World #39, a Czech player from Hradec Kralove who has built one of the most decorated doubles careers in the history of women’s tennis. Siniakova has won Grand Slam doubles titles at all four majors and completed the career Golden Slam in doubles with Olympic gold at the 2020 Tokyo Games alongside Barbora Krejcikova, a partnership that redefined what Czech doubles could achieve at the highest level. Few players in the modern game can match her doubles resume.
What makes Siniakova’s profile unusual is the extent to which her singles ranking understates her overall ability. A player who can win Grand Slam doubles titles possesses elite-level hands, court awareness, and the ability to execute under pressure. These are not qualities that disappear when she steps onto court alone. Her singles game features clean ball-striking, intelligent shot selection, and a tactical versatility that reflects thousands of hours competing at the net in doubles situations where reaction time and placement matter more than raw power.
Her all-court game is a product of the Czech development system, which has historically produced players comfortable in all areas of the court rather than specialists locked into a single playing pattern. Siniakova moves well, volleys with confidence, and constructs points with the patience of a player who understands geometry rather than relying purely on pace. This approach can be highly effective on grass and faster hard courts where net approaches are rewarded, and it gives her tactical options that pure baseliners do not possess.
The challenge for Siniakova in singles has always been sustaining the consistency required to beat top players over three sets at Slams while simultaneously maintaining her doubles commitments. The physical and mental demands of competing in both draws at every major tournament are considerable, and managing that workload is a test that only a handful of players on tour attempt seriously. Her ranking inside the top 40 while carrying a full doubles schedule is a testament to her competitive stamina and her commitment to both disciplines.
Siniakova will compete at the 2026 Grand Slams: the Australian Open, Roland Garros, Wimbledon, and the US Open. Check Czech Republic time to convert match schedules.
