In a scene that probably wouldn’t have been believed in Hollywood, Valentin Vacherot, a 26-year-old qualifier ranked No. 204, turned the Rolex Shanghai Masters into his own personal stage on October 12, 2025, defeating his cousin Arthur Rinderknech 4-6, 6-3, 6-3 to claim his first ATP Tour title.
The victory marked Vacherot as the lowest-ranked champion in ATP Masters 1000 history since records began in 1990, and the first Monegasque to win a tour-level singles title in the Open Era. Played before an excited crowd at Qizhong Forest Sports City Arena – who it’s fair to say, wouldn’t have bought tickets expecting the two finalists – the final had storylines everywhere.

Former doubles partners at Texas A&M University in 2018, Vacherot and Rinderknech spent the week in Shanghai trading encouragement, cheering from the stands, and firing off messages in their family group chat.
They even warmed up together on Stadium Court that morning. But when the first ball was struck, their camaraderie gave way to a fierce, two-hour battle that was every bit as enthralling as the predicted Medvedev v Djokovic might’ve been.
“It’s unreal what just happened,” Vacherot said post-match, his voice full of emotion. “I have no idea what is happening. It’s just crazy. I’m just so happy about my performance these past few weeks.”
Rinderknech, 30, and ranked No. 42 entering the tournament, looked poised to seize control early. Fresh off a career-best run that included upsets over Alexander Zverev, Jiri Lehecka, Felix Auger-Aliassime, and Daniil Medvedev – his 100th tour-level win – he brought confidence, experience, and firepower.
In the first set, he was nearly flawless, striking 12 winners against just two unforced errors, breaking Vacherot in the third game with aggressive net play and a 136-mph ace to seal the 6-4 frame. His early dominance suggested the more experienced Frenchman might overwhelm his younger cousin.
But Vacherot, who had already defied the odds all week, was undaunted. The Monegasque had clawed his way into the main draw as a qualifier, arriving in Shanghai just 36 hours before his first match after a swathe of late withdrawals opened a spot.
His path included victories over Laslo Djere, Alexander Bublik, Tomas Machac, Tallon Griekspoor, Holger Rune, and, in an enormous semi-final upset, four-time Shanghai champion Novak Djokovic. Remarkably, he rallied from a set down in six of his seven main-draw matches, including the final. “I feel when I am down, I have no choice and need to bring my A-game,” Vacherot explained. “In the first set I didn’t do that and he was playing better than me.”

At 3-3, Vacherot unleashed a blistering backhand winner down the line to earn a break point, converting when Rinderknech’s drop shot faltered. The crowd, sensing the shift, roared as Vacherot broke again to take the set 6-3, his deep groundstrokes pinning Rinderknech behind the baseline.
In the decider, Vacherot struck early, breaking at love with another pinpoint backhand. Rinderknech, battling back tightness that required a medical timeout, fought valiantly, saving break points in a gritty hold from 40-0 down. But Vacherot’s serve was untouchable – he dropped just three points on it in the third set, winning 92% of first-serve points and holding 15 straight points at one stage. A final forehand passing shot down the line sealed the 6-3 set and the title, sending Vacherot to his knees in disbelief.
The numbers painted a picture of Vacherot’s precision: 12 winners to Rinderknech’s 13, eight aces to 11, but just nine unforced errors to Rinderknech’s 11. He converted three of 12 break points, saved the only one he faced, and won 54% of total points, including a crucial 36% on return.
For Rinderknech, the loss stung, but his run lifted him 26 spots to a career-high No. 28, making him the ninth French finalist in Masters 1000 history. “Two cousins are stronger than one,” Rinderknech said in French during the ceremony. “You won today, congratulations. I gave it my all. I’m so happy for you, I hope there will be more. I love you so much.”
The emotional weight of the moment hit hard. After the match, Vacherot climbed into the stands to embrace his coach and half-brother, Benjamin Balleret, tears streaming down his face. At the trophy ceremony, both cousins broke down, Rinderknech even cramping mid-speech from the physical toll of his week.
Vacherot’s camera lens message was simple but poignant: “Grandpa and grandma would be proud.” Later, he elaborated, “There has to be one loser but I think there is two winners today, one family that won. And I think for the sport of tennis, the story is unreal.”

He became just the third qualifier to win a Masters 1000 title, joining Roberto Carretero (1996 Hamburg) and Albert Portas (2001 Hamburg), and the fifth player to claim his maiden tour-level title at this level. For Monaco, a nation of 40,000, the win was historic – a first for a country better known for its Grand Prix than its tennis.

I got to meet Roger today,” Vacherot said, beaming. “I mean, even outside tennis, it’s just a crazy week.” Back home, Monaco’s tennis federation hosted a watch party, erupting as their underdog hoisted the trophy. “I knew they had a big watch party,” Vacherot noted. “To hold the flag, and to be able to do that for my country is unreal.”
No one saw last week unfolding the way it did. Maybe tennis needs more of that.
