Dino Prizmic delivered the biggest win of his career on Friday at the Mutua Madrid Open, stunning World No. 6 Ben Shelton in a grueling three-hour second-round battle that ended 6-4, 6-7(4), 7-6(5). The 20-year-old Croatian qualifier, ranked No. 87, became the lowest-ranked player to defeat a Top 10 opponent at the clay-court Masters 1000 event since the tournament’s inception, securing his first-ever victory over a player ranked in the world’s top five.
The match unfolded as a relentless test of endurance and mental fortitude. Prizmic broke Shelton early in the first set and held serve to claim it 6-4. Shelton responded fiercely in the second, forcing a tie-break after saving multiple set points, ultimately prevailing 7-6(4) to level the match. The deciding set saw both players trade blows deep into the night, with Shelton matching Prizmic’s 44 winners with an equal number of unforced errors. Yet it was Prizmic who found an extra gear in the final-set tie-break, clinching it 7-5 to seal one of the most shocking upsets of the 2026 ATP Tour season.
“It means a lot,” Prizmic said after the match. “Today was a very hard match for me and I just tried to play my game, stay focused every point and it definitely worked today. I’m working a lot with my team to stay calm on the important points, but he [Shelton] is No. 6 in the world… I was waiting for my chances, and I took them in the end.” His composure under pressure stood in stark contrast to Shelton’s visible frustration, as the American struggled to convert opportunities despite his powerful serving and aggressive baseline play.
Prizmic’s victory marked his second win over a top-tier player in Madrid, having defeated former finalist Matteo Berrettini in the opening round. The qualifier’s run represents a significant milestone in his career, following notable achievements including taking a set off Novak Djokovic at the 2024 Australian Open and qualifying for the 2023 Next Gen ATP Finals. Now, with his first Top 10 win and maiden third-round appearance at an ATP Masters 1000 event, Prizmic has firmly announced his arrival on the sport’s biggest stage.
Meanwhile, Arthur Fils continued his impressive clay-court form, advancing to the third round with a straight-sets victory that kept his hopes alive for a deep run in Madrid. The French teenager, riding a surge of confidence after recent strong performances on the European clay circuit, demonstrated the consistency and tactical discipline that have made him one of the most promising young talents in men’s tennis. His progress sets up a potentially compelling third-round clash, though his next opponent remained undetermined at the time of reporting.
The Mutua Madrid Open, held annually at the Caja Mágica facility in Spain’s capital, serves as one of the premier clay-court events leading up to the French Open. Its high-altitude conditions and unique playing surface often produce unpredictable results, making Prizmic’s achievement even more remarkable. The tournament’s status as an ATP Masters 1000 event means ranking points and prize money are significantly elevated, adding further weight to the Croatian’s breakthrough performance.
Looking ahead, Prizmic is set to face Argentine qualifier Tomás Martín Etcheverry in the third round, a matchup that presents another stern test of his resilience and adaptability. Etcheverry, known for his powerful left-handed game and experience at the highest level, will glance to end the young Croatian’s fairy-tale run. For Shelton, the loss ends a five-match winning streak that began with his title triumph in Munich, raising questions about his consistency on clay as he prepares for the upcoming European clay-court swing.
As the Madrid Open progresses, the early exits of established stars like Shelton underscore the tournament’s unpredictable nature and the rising depth of talent across the ATP Tour. Prizmic’s victory not only highlights his personal growth but likewise signals a shifting landscape where qualifiers and younger players are increasingly capable of challenging the sport’s elite. For fans and analysts alike, his performance offers a compelling narrative of perseverance and potential fulfilled on one of tennis’s most demanding stages.
