Francisco Cerundolo, the top seed, is on a roll, claiming his sixth clay-court victory of the season at the BCI Seguros Chile Open. But the story doesn't end there - 24-year-old American Emilio Nava made history by becoming the first American quarter-finalist in the tournament's history, defeating Paraguayan qualifier Adolfo Daniel Vallejo in straight sets.

Why it matters

Cerundolo's continued dominance on clay courts showcases his skill and comfort on the surface, while Nava's breakthrough performance is a significant milestone for American men's tennis on South American clay. These stories highlight the depth of talent and the ongoing evolution of the sport.

The details

Cerundolo, the World No. 19, lifted the trophy on home soil in Buenos Aires earlier this month, an achievement he described as the pinnacle of his career so far. Despite a slight hiccup in Rio de Janeiro, Cerundolo dominated his match against Elmer Moller, winning in just 71 minutes. In their first Lexus ATP Head2Head meeting, Cerundolo's performance was impeccable, winning an impressive 89% of his first-serve points and not facing a single break point. As for Nava, the 24-year-old defeated Adolfo Daniel Vallejo, a Paraguayan qualifier, in straight sets, 7-5, 6-3. This achievement is monumental, as Nava is now the first American man to reach a tour-level quarter-final on South American clay since Rajeev Ram in 2017.

  • Cerundolo won the BCI Seguros Chile Open on April 10, 2026.
  • Nava defeated Vallejo on February 26, 2026 to become the first American quarter-finalist in the tournament's history.
