Paraguay has returned to the global tennis stage thanks to Daniel Vallejo. The 21-year-old defeated Bulgaria’s Grigor Dimitrov 6–4, 6–4 on Thursday in his debut at the Madrid Masters 1000, becoming only the second player from his country to win a match at this level — the first since 2014.
“I know that as the years go by I’ll keep breaking records, because Paraguay doesn’t have a long tennis history beyond Víctor Pecci and Ramón Delgado. I’m aware that if everything goes well, I’ll keep setting personal milestones. For me, all of this is historic,” the Paraguayan told a small group of media, including CLAY, in Madrid.
It is a remarkable moment, one that has him brimming with confidence. “I have a lot of belief in myself and I know I can go toe to toe with a player like Grigor. Of course I was surprised by his quality and some of the shots he produced at times, but I’m aware that I can be at his level and that of other players. That also makes me believe I can beat this kind of opponent,” the former world No. 1 junior told CLAY.
Despite his short career, Vallejo is already part of the most important trio in Paraguayan tennis alongside Víctor Pecci and Ramón Delgado, two figures he openly admires.
“Pecci will always be an idol for all of Paraguay because he’s probably the country’s greatest athlete, but I experienced Ramón Delgado and still do, because he’s part of my team. He’s someone who has been close to me since I was very young, supporting me to this day — I speak to him every day. I hope I can have a career like his,” he told CLAY at the Caja Mágica.

Víctor Pecci reached world No. 9, was a finalist at Roland Garros in 1979 and a semi-finalist in 1981, and won 10 ATP singles titles; while Ramón Delgado made the fourth round of the French Open in 1998, climbed to No. 52 in the world rankings and recorded nine wins at Masters 1000 level.
Reaching the second round in the Spanish capital is the culmination of a systematic effort the South American has been building since mid-2025. In the closing months of last season he won two Challenger titles, and this year he has also lifted trophies in the Itajaí and Concepción Challengers. At ATP level, in 2026 he has already reached the round of 16 in Houston and Santiago, as well as the third round of qualifying at the Australian Open. For now, he is the new world No. 85.
“I’m just getting started, so people are only beginning to get excited about me, but over the course of my career I hope people can be moved by this and also want to take up the sport and follow me, because in the end that’s what you want — to help put both the sport and your name on the map in your country,” he reflected on the impact his success could have in opening up tennis in Paraguay, a country where the sport is still associated with the more affluent sectors of society.
The Vallejo phenomenon is another example of a paradigm shift looming in world tennis: the growing presence of nations without a strong tradition at the sport’s top events. Evidence of this can be seen in the women’s circuit with the Philippines’ Alexandra Eala and Turkey’s Zeynep Sönmez, and on the men’s side with the Paraguayan and Peru’s Ignacio Buse.
