Latin American tennis will field one of its deepest contingents of the season at the 2026 Cincinnati Open, with 14 players from six countries currently listed across the ATP and WTA singles fields. The group includes 12 men and two women, led by Argentina’s Francisco CerĂșndolo, Brazil’s JoĂŁo Fonseca, Peru’s Ignacio Buse, Chile’s Alejandro Tabilo, and â in the women’s draw â Colombia’s Camila Osorio and Brazil’s Beatriz Haddad Maia.
Argentina accounts for eight of the entrants, giving the country by far the largest Latin American delegation at the combined ATP and WTA 1000 tournament. The published lists remain subject to withdrawals and other changes before the draws are completed. Rankings attached to the entries are entry-list positions, not finalized tournament seeds.
CerĂșndolo arrives as Latin America’s highest-ranked entrant, listed at No. 22 after producing one of the strongest seasons of his career. The 27-year-old won the Buenos Aires title in February before capturing his first ATP 500 trophy at Queen’s Club in June. That victory made him the first Argentine man to win the historic grass-court tournament and moved him back toward the world’s top 20.
Fonseca will be another major attraction. The 19-year-old Brazilian is listed at No. 28 after reaching his first ATP Masters 1000 quarterfinal in Monte Carlo and making a breakthrough run to the Roland Garros quarterfinals.
Fonseca’s Paris run included a third-round, five-set comeback from two sets down against Novak Djokovic â a result that made him the first teenager in three decades to win back-to-back Grand Slam matches from two sets down, and the first to oust a former Roland Garros champion from that deficit since Michael Chang. He followed it by beating Casper Ruud to reach the last eight before falling to Jakub Mensik in the quarterfinals.
CerĂșndolo and Fonseca are joined inside the tournament’s published top 32 by Tabilo at No. 30 and Argentina’s TomĂĄs MartĂn Etcheverry at No. 31. Those four players would be positioned to receive seeds if the rankings and field remain similar when the draw is made. Final seedings, however, will be determined closer to the tournament and could shift because of ranking changes or withdrawals.
Etcheverry won his first ATP Tour title at the Rio Open in February, defeating Tabilo in the final after completing two matches on the tournament’s final day. The result gave Argentina another established contender beyond CerĂșndolo. Tabilo has also been showing improved form. In addition to reaching the Rio final, the Chilean advanced to the semifinals in BĂ„stad in July before losing a close three-set match to Andrey Rublev.
Buse may be the most important player sitting just outside the projected seed line. The 22-year-old Peruvian is listed at No. 35 following a remarkable rise that included winning the ATP 500 tournament in Hamburg as a qualifier. His victory over Tommy Paul in the Hamburg final made Buse the first Peruvian to win an ATP singles title since Luis Horna in 2007. He later became the first Peruvian man in more than three decades to win a Wimbledon main-draw singles match.
Argentina’s full group also includes SebastiĂĄn BĂĄez at No. 56, RomĂĄn AndrĂ©s Burruchaga at No. 60, Juan Manuel CerĂșndolo at No. 50, Mariano Navone at No. 47, Thiago AgustĂn Tirante at No. 57 and Camilo Ugo Carabelli at No. 69. Navone has already collected a significant result this season, winning his first ATP Tour title in Bucharest in April.
Paraguay will be represented by Adolfo Daniel Vallejo, listed at No. 63. Vallejo recently reached the BÄstad semifinals, where he pushed defending champion Luciano Darderi to three sets and became the first Paraguayan to reach an ATP Tour semifinal since Ramón Delgado in 2002.
Two women from the region appear in the published WTA field. Osorio, Colombia’s long-time No. 1, is joined by Haddad Maia, a former world No. 10 and 2023 Roland Garros semifinalist who is the most decorated Latin American woman in the draw. The regional representation still tilts heavily toward the men’s tournament, where Argentina alone accounts for eight entrants.
The Cincinnati Open will begin with qualifying on August 11, followed by main-draw competition and the men’s and women’s singles finals on August 23.
The tournament features 96-player singles fields and is one of five events that stage ATP and WTA 1000 competitions at the same location. Its expanded format followed a $260 million redevelopment of the Lindner Family Tennis Center in Mason, Ohio. For Latin American players, Cincinnati represents both an opportunity to collect valuable ranking points and a final major test against elite competition before the US Open.
