Calò was born in Trieste in the Friuli-Venezia Giulia region of Italy, and began his career in the youth sides of local team Triestina. When the club experienced financial difficulties in 2012, Calò was released by the club and became a free-agent. He then moved to Genoa and attended the Istituto Socio Economico a Genova, and was soon signed by Sampdoria. Heralded as a 'new Andrea Pirlo', he rejected interest from other Serie A giants Juventus, Udinese, Fiorentina and Atalanta, in order to play in the Blucerchiati youth teams. After his promotion in 2014, he gradually became an important player for the Primavera side, eventually making over fifty appearances and scoring ten goals.
After two years in the Primavera side, Sampdoria decided to loan Calò out in order for him to gain professional match experience. On 6 July 2016, he moved to Pontedera in Lega Pro. His debut for the Granata came in a 1–3 Coppa Italia loss to Foggia on 31 July 2016. Despite beginning the season playing sporadically, he eventually became a more regular feature in the centre of midfield, and scored his first goal for the club on 23 December 2016 in an eventual 1–2 loss to Siena.
