Katerina Siniakova added another accolade to her decorated career by capturing the mixed doubles title at Wimbledon alongside Sem Verbeek. The pair triumphed in straight sets, 7-6 (3), 7-6 (3), against Luisa Stefani and Joe Salisbury on Thursday. Siniakova, a 10-time Grand Slam women’s doubles champion from the Czech Republic, sealed the win with a powerful smash on the first match point. The moment unfolded in front of a half-full but enthusiastic Centre Court crowd. A Special First for Verbeek For Verbeek, the title marks his first major victory. The Dutchman celebrated the milestone in heartwarming fashion, leading the crowd in singing “Happy Birthday To You” to his father. Verbeek played NCAA Division I college tennis at the University of the Pacific from 2012–16 before turning fully pro. On the professional circuit, he claimed his first ATP Challenger doubles title in Winnipeg in 2018 and later won his first ATP Tour doubles title at the 2024 Hall of Fame Open with André Göransson. 2025 has been a breakout year: Verbeek was a surprise finalist at the Australian Open doubles, reaching the semis with Göransson, and in July, captured his first Grand Slam title by winning the Wimbledon mixed doubles alongside Katerina Siniakova. At age 31, he is among the leading Dutch doubles players and continues to build his reputation in high-level men’s and mixed doubles competition. Doubles Dominance From Siniakova Siniakova’s accomplishments extend beyond Grand Slam tournaments.
