“It has been an incredible week,” said Nava, expressing his feelings in Spanish. “My team and I executed our plan perfectly. The Argentine crowd adds an extra layer of excitement; it makes the atmosphere electric when they’re fully engaged.”

Nava, under the guidance of Argentine coach Diego Cristin, has now secured all six of his Challenger titles on clay. Earlier this season, he achieved a remarkable 19-match winning streak on clay, which included three titles in Asuncion, Concepcion, and Sarasota, along with a runner-up finish in Tallahassee.

At just 23 years old, he made his debut in the Top 100 last week and is currently positioned at No. 90 in the PIF ATP Live Rankings.
