In 1996, he was bought by Lazio, and loaned out to Vicenza. He did not become a regular at Vicenza and returned to Lazio, who once again sent him on loan to gain experience. This time he was sent south to Reggina where, along with Andrea Pirlo, he was a key protagonist in their Serie A survival.
Following his spell in Calabria, Baronio was sent to Fiorentina, and continued to develop, firmly considered one of Italy's brightest young talents, yet unable to find a place in the Lazio squad which at the time was one of the best in the world.[according to whom?]
In 2000, he was awarded the title of Serie A Young Footballer of the Year.
In 2002, Baronio was sent to Perugia, where he had a poor year in a side which was relegated to Serie B. Baronio then headed to Chievo and Udinese where he became a regular and began to show signs of becoming the elite footballer many expected. This culminated in a return to Lazio, as well as a debut with Marcello Lippi's Azzurri in 2005.
Baronio failed however, to seal a place in the national team, missing the World Cup and he also failed to establish himself as a regular at Lazio, with Cristian Ledesma filling the void left by Fabio Liverani.
Offered a loan spell in La Liga with Levante,Baronio instead refused and opted to try and force his way into the Lazio side. He has never managed to achieve this, and remains an unfulfilled talent.[according to whom?]
Baronio was sent on loan to hometown club Brescia, for the 2008–09 season, and was a key player[according to whom?] in the rondinelle's promotion push, ultimately losing to Livorno in the playoffs. At the end of the season, he returned to Lazio with the intention to reclaim a first team place following the departure of coach Delio Rossi and the appointment of new boss Davide Ballardini, who promptly presented him as a regular in the successful 2009 Supercoppa Italiana game against Inter and later also in the following Serie A league games, partially due to Ledesma was frozen by the club for contract dispute. After the dismissal of Ballardini and the appointment of Edy Reja as new head coach, Baronio found again limited space in the first team and left Lazio on 30 June 2010 after his contract expired.
In 2005, Baronio was called by Lippi, and made his senior debut in a summer tournament in the USA against Ecuador, in what remains his only Azzurri appearance to date.
