Seeded seventh, Olympic champion Tokyo in men's doubles Mate Pavic, 30, and Lyudmyla Kichenok, also thirty, win mixed doubles title, by beating Belgium's Joran Vliegen and China's Xu Yifan 6-4, 6-7 (9-11), 6-3.
Kichenok is first Ukrainian to win a Wimbledon title.
Former ATP Doubles World No.1 Pavic now has three Grand Slam mixed doubles titles to go with his three Grand Slam men's doubles titles. His previous mixed doubles major titles came at the 2016 US Open with Laura Siegemund and the 2018 Australian Open with Gabriela Dabrowski.
"It feels amazing to be Wimbledon champion in mixed doubles," Kichenok said in her post-match press conference. "I really enjoyed playing with Mate. He's a great player. ... It was really a wonderful time for me the past ten days.
"We both are just working hard on our game every day. We both are trying to play aggressively. On grass it works well. That's the key. It worked for us this tournament."
