Crescenzi is a product of the Roma youth system. He is an attacking right back, with the ability to play also on the left side.
On August 5, 2011 he joined Bari on a long season loan deal that brought teammates Simone Sini and Adrian Stoian to the team as well. The loan also inserted a co-ownership option and Crescenzi also extended his contract to 2014 in order to formalize the deal. He would earn a gross annual salary of €177,000 in 2013–14 season. On 24 August his teammate Salvatore Masiello threw a plate that hit Crescenzi in the arm, necessitating 40 stitches and leading Bari to seek the termination of Masiello's contract.
