Atlético Rafaela

Barovero started his professional career in 2003 playing for Atlético de Rafaela in the Primera B Nacional (Argentine second division). In his first season, the club won the championship and promotion to the Primera División. Barovero was used as the club's third choice goalkeeper in the first division, behind Ángel David Comizzo and Ezequiel Medrán. Rafaela was relegated at the end of the 2003–04 season, but Barovero stayed with the club and established himself as the first choice goalkeeper back in the B Nacional. He totalled 113 appearances for Atlético de Rafaela, before his move to Huracán (of the first division) in 2007.

Since then he's been one of the stars of the Argentine side and was named Man of the Match in more than one occasion, but most notably on an intense fixture in the 2013 Copa Sudamericana against Buenos Aires rivals San Lorenzo to advance to the Round of Sixteen. He won multiple titles with the squad, most notably the 2015 Copa Libertadores. The fans consider him an idol of the team.
