Sgarbossa was passed over in the 2010 NHL Entry Draft but was signed as a free agent by the San Jose Sharks to a three-year entry level contract on September 21, 2010. Sgarbossa was signed after appearing in the NHL YoungStars tournament for the Sharks, scoring 3 goals and 4 points in 2 contests. Sgarbossa was again on the move in the OHL the following 2010–11 season when he was traded by the Spirit to the Sudbury Wolves. He immediately made an impact with the Wolves to lead the team in scoring for the remainder of the campaign with 62 points in only 37 games.
