WIMBLEDON, England – Pacific men's tennis legend Sem Verbeek and his partner Katerina Siniakova won the 2025 Wimbledon Mixed Doubles Championship on Thursday on Centre Court of the All England Lawn Tennis and Croquet Club.
 
It was the first major championship for Verbeek, who graduated from Pacific in 2016 with a degree in pre-med. Verbeek, from the Netherlands, and Siniakova, from the Czech Republic, won the championship in straight sets 7-6 (3), 7-6 (3) over Joe Salisbury from England and Luisa Stefani from Brazil.
 
After the match, Verbeek announced it was his father, Frank Verbeek's birthday and the crowd sang 'Happy Birthday' to him.
 
Verbeek and Siniakova dropped just one set during the tournament. They won the quarterfinals, semifinals and finals in straight sets.
 
Verbeek arrived at Pacific as a walk-on and won 2013 Big West Freshman of the Year and All-Conference honors in singles and doubles. He was put on scholarship as a sophomore and went on to win 2016 West Coast Conference Player of the Year as a senior. He won 125 matches at Pacific, the second-most in program history.
 
"Four years can really turn into a beautiful painting for anyone," Verbeek said last year. "Pacific was the perfect university for me with the small class sizes and the personal relationships I formed with the professors – it was instrumental for me as I was growing as a person. If I didn't go to Pacific, I probably wouldn't have made it professionally. Pacific will always have a special place in my heart."

Verbeek has played in six consecutive grand slams. He debuted at the 2024 French Open in men's doubles with Reese Stalder. Verbeek recorded his first grand slam win at 2024 Wimbledon in men's doubles with Romain Arneodo. Verbeek also won men's doubles matches at the 2024 U.S. Open and the 2025 French Open with Andre Goransson.
