Among the players, Francisco Comesaña (68th), Mariano Navone (74th), and Juan Manuel Cerúndolo (83rd) stand out as pre-qualified. Other participants include Roman Burruchaga, the current Buenos Aires Challenger champion, Juan Pablo Ficovich, Alex Barrena, Santiago Rodríguez Taverna, Genaro Olivieri, Lautaro Midón, Andrea Collarini, and Facundo Díaz Acosta. The draw is completed by a significant international presence featuring players like Carlos Taberner, Vit Kopriva, Chun-Hsin Tseng, Hugo Dellien, Daniel Galán, Marco Cecchinato, and several Brazilian representatives, which strengthens the tournament's competitive profile. Camilo Ugo Carabelli, a Buenos Aires-born player and the current champion, will defend his title at the Quini 6 Rosario Challenger, held from February 1-8, 2026, at the Jockey Club de Rosario. The event is organized by Torneos and supported by the Government of Santa Fe Province. Ugo Carabelli's victory in the 2025 edition, where he defeated Hugo Dellien in the final, marked the eighth Challenger title of his career and the start of his best professional season, which also included ATP semi-finals in Rio de Janeiro and Santiago, as well as notable performances in Bastad and Umag. This run allowed him to enter the top 50 of the world rankings for the first time, a position he still holds. With Ugo Carabelli's confirmation, the number of Argentines in the main draw rises to twelve.
