After developing in the Roma Youth System, he played for 13 seasons (253 games, 6 goals) in the Serie A, for the A.S. Roma senior (1988–2000), and subsequently Udinese Calcio (1993–94), Brescia Calcio (2000–2004), and Bologna F.C. 1909 (2004–05).
He began his professional career with Roma in 1988, later moving on a two-season loan to Serie C side Casertana, to gain experience, in 1990 helping the team to gain Serie B promotion in 1992. He returned to Rome in 1992, the following season, but struggled to gain playing time, and was sent on loan to Udinese the next season, in 1993. He moved back to Roma in 1994, where he played as a starter under managers Carlo Mazzone, Zdeněk Zeman, and Fabio Capello. He later moved to Brescia in 2000, where he joined his former Roma manager Mazzone, spending four seasons with the club alongside Roberto Baggio, and later, his former Roma team-mate Luigi Di Biagio. He followed Mazzone to Bologna in 2004, although he was unable to help the club avoid Serie B relegation; he retired at the end of the season.
Petruzzi played his only game for the Italy national football team on June 21, 1995, in an international friendly match against Germany, in Zurich, under manager Arrigo Sacchi, which Italy won 2–0. He was called up for two more national team games in 1995 and 1997, but did not make an appearance on either of those occasions.
After retiring, Petruzzi initially worked as a pundit for Rete Sport, in Rome. He later worked as a youth coach.
