“I had a pretty good week,” said the bilingual Nava in Spanish. “My team and I did a good job. I like [the Argentine crowd] because it adds a little more tension [when facing an Argentine] and it makes everything a little more fun when the crowd is at 100 per cent. I loved it.”
Nava, who is coached by Argentine Diego Cristin, has earned all six of his Challenger trophies on clay. Earlier this season, he went on a 19-match winning streak on the surface, a run during which he won three titles (Asuncion, Concepcion and Sarasota) and finished runner-up in Tallahassee.
The 23-year-old made his Top 100 debut last Monday and is currently No. 90 in the PIF ATP Live Rankings.
Reigning NCAA singles champ Zheng saves two championship points
In other Challenger action, reigning NCAA singles champion Michael Zheng saved two championship points to capture his second title of the season. The Columbia University star rallied past Martin Damm 3-6, 6-3, 7-5 in an all-American final at the indoor Columbus Challenger in Ohio.
Damm, who was aiming for his first Challenger trophy, held championship points on return at 5-4, 15/40 in the decider. Yet Zheng prevailed, backing up his Chicago Challenger triumph from last month to extend his winning streak at that level to 10. Zheng, 21, is up 85 places to No. 227 in the PIF ATP Live Rankings.
Make that title number ✌️
