Latin America will send one of its deepest groups of men’s players in recent years to the 2026 Cincinnati Open, led by established Argentine contender Francisco Cerúndolo, Brazilian star João Fonseca and Peru’s rapidly rising Ignacio Buse. The combined ATP and WTA 1000 tournament will hold qualifying rounds on August 11 and 12 at the Lindner Family Tennis Center in Mason, Ohio. The expanded 96-player main draws begin August 13, with the singles finals scheduled for August 23.
The tournament field includes players from Argentina, Brazil, Chile, Colombia, Peru and Paraguay. Several will arrive with realistic hopes of advancing beyond the opening rounds rather than simply adding regional representation to a field headed by the world’s leading players.
Fonseca is likely to attract the most attention. The 19-year-old Brazilian is listed at No. 28 in the Cincinnati field and has already developed one of the loudest and most visible fan bases on the men’s tour. Tournament organizers specifically identified him as a player whose supporters bring flags, noise and energy wherever he competes.
His 2026 season has included interruptions caused by back and shoulder problems, but he reached two clay-court quarterfinals and advanced to the third round at Wimbledon. Cincinnati will offer another test of how quickly he can adjust to the faster North American hard courts ahead of the US Open.
Francisco Cerúndolo enters as Latin America’s highest-ranked man in the announced field at No. 22. The 27-year-old has produced one of the strongest seasons of his career, winning titles in Buenos Aires and at Queen’s Club in London.
His Queen’s Club victory was especially significant. Cerúndolo became the first Argentine to win the tournament and earned the first ATP 500 title of his career, showing that his success is no longer limited to clay. That versatility could make him the region’s most credible candidate for a deep Cincinnati run.
Cerúndolo also leads an unusually large Argentine contingent. Tomás Martín Etcheverry, Mariano Navone, Juan Manuel Cerúndolo, Sebastián Báez, Román Andrés Burruchaga, Thiago Agustín Tirante and Camilo Ugo Carabelli are all listed in the main draw.
Etcheverry is ranked No. 31 in the field after reaching the semifinals in Kitzbühel, while Navone, Báez and the younger Cerúndolo brother give Argentina additional depth. The size of the delegation reflects the country’s continuing ability to produce tour-level players even without a current superstar competing near the very top of the rankings.
One of the more intriguing names is Ignacio Buse. The 21-year-old Peruvian is listed at No. 35 and has climbed rapidly enough to enter the discussion around possible seeding at major tournaments.
Buse reached the Rio Open semifinals earlier this year after defeating former Wimbledon finalist Matteo Berrettini. His rise is particularly notable because Peru does not have the player-development depth or tournament infrastructure associated with Argentina or Brazil. Cincinnati will provide another opportunity to measure his progress against a field containing nearly every leading player in the world.
Chile’s Alejandro Tabilo is another dangerous opponent. The left-hander is ranked No. 30 in the Cincinnati field and reached the semifinals in Bastad in July before losing a close three-set match to Andrey Rublev. Tabilo’s serve and left-handed patterns can make him an uncomfortable early-round matchup, particularly if he can transfer his recent clay-court form to the hard courts. He has already defeated Fonseca this season, winning their three-set meeting in Buenos Aires.
Paraguay will be represented by Adolfo Daniel Vallejo, who is listed at No. 63. His presence adds another country to a men’s field that is considerably more geographically diverse than Latin American representation on the women’s side.
Colombia’s Camila Osorio is currently the region’s only confirmed direct entrant in the women’s main draw. Her speed, defensive ability and willingness to extend points have helped her compete effectively across surfaces, but she will face a difficult field containing the full women’s top 10 and numerous Grand Slam champions.
Other Latin American women will have to earn their places through qualifying. Colombia’s Emiliana Arango, Argentina’s Solana Sierra and Nadia Podoroska, and Mexico’s Renata Zarazúa are included in the 48-player qualifying field. Twelve women will advance to the main draw after two rounds.
The final draw will determine whether Latin America’s leading players receive manageable openings or immediate assignments against the tournament favorites. Even before those matchups are known, Cincinnati offers a revealing test. Cerúndolo has already demonstrated that he can win a major title away from clay.
Fonseca is trying to convert exceptional promise into consistent results. Buse is carrying Peruvian tennis into unfamiliar territory, while Tabilo and Argentina’s deep group remain capable of disrupting almost any section of the draw.For Latin American tennis, the question in Cincinnati will not be whether the region is represented. It will be how many of its players remain standing when the tournament reaches its decisive second week.
