Czech doubles specialist Kateřina Siniaková reached a new milestone in her already glittering career on Thursday, teaming up with Dutchman Sem Verbeek to win the 2025 Wimbledon Mixed Doubles Championship.

The pair defeated Brazil’s Luisa Stefani and Britain’s Joe Salisbury in a tight straight-sets final: 7–6(7–3), 7–6(7–3).

The victory marks Siniaková’s first Grand Slam mixed doubles title, adding to an exceptional record that already includes 10 Grand Slam titles in women’s doubles and 30 career doubles titles overall.

But the moment was perhaps even more meaningful for Verbeek, who was appearing in his first-ever Grand Slam final. The 31-year-old Dutchman, a relatively unknown name on the doubles circuit, rose to the occasion on Centre Court, keeping his cool in both tiebreaks and showing outstanding net coverage throughout the match.

“Kateřina, thank you so much. It’s been an honour to compete alongside such a great doubles legend—one of the best to ever do it. Thank you for making this a Thursday I’ll remember for the rest of my life,” said a beaming Verbeek after the final.

Siniaková, now a Wimbledon champion in both women’s and mixed doubles, reflected on the experience with gratitude.

“To be back on Centre Court—this atmosphere is always amazing—so I’m just really happy I could be here again.”

There were no breaks of serve in the final, but Siniaková and Verbeek remained locked in during both tiebreaks. Their sharp returns and seamless teamwork made the difference against the experienced duo of Stefani and Salisbury.

With this win, Siniaková’s Grand Slam title haul now includes:

• Australian Open (Women’s Doubles): 2022, 2024, 2025
• French Open (Women’s Doubles): 2018, 2021, 2024
• Wimbledon (Women’s Doubles): 2018, 2022, 2024
• US Open (Women’s Doubles): 2022
• Wimbledon (Mixed Doubles): 2025

Siniaková, who partnered Tomas Machac to win the gold medal at last year’s Paris Olympics, is the WTA doubles No. 1 player who has 10 major titles in women’s doubles, including at this year’s Australian Open alongside Taylor Townsend

Siniaková and Townsend will compete in the Wimbledon women’s doubles semifinals Friday.

The 31-year-old Verbeek, No. 31 in the PIF ATP Doubles Rankings, led the Centre Court crowd in singing ‘Happy Birthday’ to his father, Frank, during the trophy ceremony.
