After another strong season in the VFL, he was elevated to the senior list, making his debut for Carlton in Round 21, 2004 against Melbourne.
He was the last Carlton player to make his AFL debut at the club's traditional home ground at Princes Park.
In Round 7, 2008 against the West Coast Eagles at Subiaco, Carrazzo picked up an AFL career high 42 disposals.
With the recruitment of Chris Judd and the return of Nick Stevens from injury, Carrazzo was moved out of the midfield, and spent most of the season playing as a rebounding defender.
He played two games with the Northern Bullants to regain match fitness, and in the second amassed 55 disposals against Box Hill, before being returned to the AFL seniors for Round 5.
A further injury to his thumb kept him sidelined for another four weeks, before returning to play all remaining games, including Carlton's elimination final loss to the Brisbane Lions.
He attracted particular praise for a two-way shutdown role against Collingwood's Scott Pendlebury in Round 3, 2012;[4] but the following week his shoulder blade was broken in a strong driving tackle from behind by Essendon's Sam Lonergan, and he missed the next two months.
