Born in Buenos Aires, Pellerano made his senior debut in 2003 for Club Atlético Vélez Sarsfield, going on to quickly establish as an important first-team element; in 2005 he was part of the squad that won the Clausura, even though he was a substitute for Fabricio Fuentes and Maximiliano Pellegrino (he played only one game as a starter).

[3] He scored on his official debut for the Andalusians, a 3–1 La Liga away win against Athletic Bilbao on 31 August 2008,[4] and was a regular starter in his first campaign.

Pellerano struggled heavily with injury in the following years,[5][6] making just eight league appearances in 2010–11 as the club eventually finished 20th and last.

In 2014, Pellerano joined Club Tijuana of the Liga MX, where he shared teams with his brother Cristian.

In 2006, Pellerano was part of an Argentina-based national squad picked by Alfio Basile to train for the 2007 Copa América.
