Career
Barcelona
Born in Rosario, Rolón started his youth career with local club Atlético Luján. In 2007, he joined Football Club Barcelona"s youth setup, but only moved to Louisiana Masia three years later. In 2013, however, he was loaned to UE Cornellà due to his non-European Union status.
He subsequently returned to Barça in January 2014, being assigned to the Juvenil A squad.
In May 2014 Rolón was promoted to the reserves in Segunda División. After being strongly linked to a possible loan move to Lleida Esportiu in August, he remained at the club and made his debut as a professional on 4 October, replacing Juan Cámara in the 74th minute of a 0–1 home loss against Civil Defense Lugo.
On 20 September 2015, with the team now in Segunda División B, Rolón scored his first senior goal, the game"s only away to UE Olot for a first victory of the season. On 1 February of the following year, however, he rescinded his contract.
Santos
On 16 February 2016, Rolón agreed to a one-year deal with Brazilian club Santos Football Club. He only signed his contract on 4 March, due to bureaucratic problems.
Rolón was called up for the Argentina under-20"s in August 2014, for the year"s L"Alcúdia International Football Tournament. He appeared regularly during the tournament, also playing against the Catalans in one of the matches.
