João Fonseca’s professional journey
At 19, João Fonseca has already notched achievements that position him as Brazil’s top tennis prospect. In his first full ATP season, the Rio native climbed to 45th in the world rankings, a remarkable feat for his age. His resume includes a Challenger title in Canberra in early 2025, plus third-round runs at Roland Garros and Wimbledon. At the US Open, he matches the best Brazilian performances of the last decade, echoing Thiago Monteiro (2022) and Felipe Meligeni Alves (2023).
Despite vomiting during the Kecmanovic match, Fonseca showed resilience. He credited the crowd’s energy for his success.

The prize money increase reflects tennis’s growing professionalization, aiming to attract and retain talent in a costly sport. For Fonseca, each round advances his ability to invest in coaching, travel, and fitness.

Tough road ahead in the tournament
The US Open draw places João Fonseca in a competitive bracket with high-caliber opponents. After defeating Kecmanovic, he faces Tomas Machac, who dispatched Luca Nardi with ease in the first round. The 21st-seeded Czech is known for consistency on hard courts, making the upcoming match a critical test for Fonseca. The bracket also includes American Taylor Fritz, ranked 4th, a potential hurdle in later stages.
The men’s draw features top names like defending champion Jannik Sinner, Carlos Alcaraz, and Novak Djokovic, chasing his 25th Grand Slam title. While not a favorite, Fonseca has a chance to upset, as seen in his Australian Open 2025 win over Andrey Rublev. His youth and energy could shine in grueling matches, especially in a tournament known for launching new stars.
US Open’s legacy for Brazilian tennis
The US Open holds a storied place in Brazilian tennis history, from Maria Esther Bueno’s three titles in the 1960s to Gustavo Kuerten’s runs. João Fonseca’s main-draw debut rekindles hopes for a new generation to compete at the elite level. His presence, amplified by the record prize money, could attract sponsors and boost tennis in Brazil.
The Brazilian crowd, packing the stands in New York, shows growing support for Fonseca. A 2023 US Open junior champion, he now aims to make his mark as a professional. The tournament offers not just financial rewards but also invaluable experience on one of tennis’s grandest stages.
- Historic Brazilian moments at the US Open:
- Maria Esther Bueno: champion (1960, 1963, 1964).
- Gustavo Kuerten: round of 16 (1999, 2001).
- João Fonseca: junior champion (2023), main draw debut (2025).
Expectations for the next round
Fonseca’s clash with Tomas Machac, likely set for Wednesday, August 27, will be a tough challenge. The Czech, who crushed Nardi 6/3, 6/1, 6/1, is more experienced and higher-ranked. Yet Fonseca has a history of toppling favorites, like his Australian Open victory over Rublev, then ranked 9th. New York’s hard courts suit his aggressive style, but consistency will be key.
Brazilian fans hope Fonseca can overcome his physical setback from the opener. His preparation, including a Challenger win in Canberra, bolsters his confidence. A second-round win would secure $237,000 (R$1.28 million) and match his best Grand Slam performance.
- Factors for the next match:
- Fonseca’s recovery from his debut health issue.
- Adaptation to hard courts, where Machac excels.
- Support from the Brazilian crowd in New York.
