In a stunning upset at the BCI Seguros Chile Open on February 24, 2026, Emilio Nava defied the odds to defeat the former Top 10 player Matteo Berrettini. The No. 79-ranked Nava breezed to a 6-3, 6-4 victory, outperforming Berrettini's powerful serve and securing his biggest win since Toronto last July. But here's where it gets controversial: some tennis experts argue that Nava's success against Berrettini was more about altitude advantage than his own skill. Nonetheless, Nava's win against World No. 57 Berrettini was a significant achievement, and he is now on a roll, having won 10 of his past 13 matches on Chilean soil. In other matches, Elmer Moller secured his maiden ATP Tour main-draw win, and Vilius Gaubas and Mariano Navone advanced to the second round. Will Nava's win spark a new era for tennis in Chile? Or is it just a fluke? We'll let you decide. Leave your thoughts in the comments below!
