The following year, Nino represented the youth national team in four games in the Americas Under-19 Championship, and again in the same competition during 2005.
Argentina were promoted from their group and Nino played in Division One games against United States, Canada and the Cayman Islands.
Nino maintained a good bowling average, taking six wickets during the competition.
Argentina were promoted at the end of the campaign into Division Two, despite losing their first fixture, a last-ball game against an Italian team including former Lancashire all-rounder Joe Scuderi.
In November 2021, he was named in Argentina's Twenty20 International (T20I) squad for the 2021 ICC Men's T20 World Cup Americas Qualifier tournament in Antigua.
