Karolina Muchova and Jakub Mensik Claim US Open Mixed Doubles Title
Karolina Muchova and Jakub Mensik walked into Arthur Ashe Stadium on Wednesday as a new pairing with matching outfits and modest expectations. They walked out as US Open mixed doubles champions.
The Czech duo edged Belinda Bencic and Flavio Cobolli 6-3, 1-6, 10-6 to claim their first Grand Slam title together, riding Mensik’s thunderous serve and Muchova’s poise in the decisive moments of a sharply swinging contest.
Czechs strike first
The opening set belonged to them from the start. Mensik, 20 years old and unbothered by the size of the stage, set the tone with heavy first serves and aggressive positioning at the net. Muchova read the play beautifully behind him, picking off volleys and keeping Bencic and Cobolli under constant pressure.
The reward came quickly. In under half an hour, Mensik drilled an ace past Bencic on set point, a clean, bold finish that underlined how confidently the Czechs had taken control.
Bencic bites back
The match turned sharply in the second.
Bencic, stung by the flat opening, stepped up on the return. She ripped a winner to break for 3-1, finally cracking the Czech serve and dragging her team into the contest. Cobolli settled with her, finding better rhythm on his own delivery and holding his ground at the net.
The pressure shifted. Muchova and Mensik, so fluid in the first set, suddenly looked rushed. Errors crept in, and Bencic kept swinging freely. She levelled the match with a touch of fortune, her forehand clipping the net cord and skipping beyond Muchova’s reach to seal the second set 6-1. From cruise control to crisis in a handful of games.
Match tiebreak, big-stage composure
Everything came down to the 10-point match tiebreak, and that is where Mensik’s serve and the pair’s chemistry resurfaced.
The young Czech took charge, pounding in first serves and closing in tight at the net. His reactions were sharp, his intent obvious: this was not going to slip away. Point by point, the Czechs built a cushion.
Mensik’s firm volley for 8-4 felt like a breaking point. Muchova then produced her best serve of the night to bring up championship points, a timely strike that underlined her experience in big moments.
One more swing of Mensik’s arm finished it. Another ace, this one for the title. He leapt in celebration, soaking in the roar of Ashe as the pair secured the first trophy of the season’s final Grand Slam.
From match points down to the title
Their run to the title had already flirted with disaster.
In the semifinals, Muchova and Mensik stared down two match points against Mirra Andreeva and Andrey Rublev, surviving by the finest of margins to even reach the final. That escape seemed to harden them. When the tiebreak arrived against Bencic and Cobolli, they played like a team that had already walked the tightrope and refused to look down again.
During the trophy ceremony, Muchova joked that “in the end the matching outfits made the difference for us,” a light touch after a tense week. She admitted she had not expected to be standing on court with the trophy, saying they had come out “just to have fun and enjoy these mixed doubles” before finding themselves champions. “So we did something right,” she added, after offering warm congratulations to Bencic and Cobolli.
For the US Open, this title match was another small vindication of its revamped mixed doubles format. The 16-team draw, packed with leading singles names, started on Tuesday and is designed to pull bigger crowds into the grounds in the days before the singles main draw.
For Muchova and Mensik, it’s something else entirely: a shared Grand Slam title, earned in the glare of Arthur Ashe, and a statement that a partnership born to “have fun” might just be one to watch.
