Fresi was born in La Maddalena, Sardinia. His first professional championship was with Salernitana, with whom he conquered the promotion to Serie B. At the conclusion of that season he was selected for the Italian Under-21 side for the first time, of which he later became captain.
After another Serie B season with Salernitana, in which his team neared promotion to Serie A, he was acquired by Inter. Fresi played for the Milanese team until 1998, winning an UEFA Cup in 1998. In that year he was loaned back to Salernitana, and later played for Napoli and Bologna, returning to play frequently; this gained him a place at Juventus F.C., but here Fresi found few presences in Serie A, although he was part of the team which won the scudetto during the 2002–03 Serie A season, and the 2002 Supercoppa Italiana, leaving the club in 2004.
Later he played for Perugia, Catania and again Salernitana, in which he remained despite the relegation to Serie C1 in 2005. His last team was Battipagliese, playing in the Eccellenza series, during the 2005–06 season.
Fresi was selected six times for the Italian football national team between 1995 and 1999, his most recent one coming under manager Dino Zoff, but never played a single match for Italy. Fresi did make 17 appearances with the Italy national under-21 football team between 1994 and 1996, scoring one goal, and frequently captaining the squad; he was a member of the team that won the 1996 UEFA European Under-21 Championship. Fresi also represented Italy at the 1996 Summer Olympic Games in Atlanta, making three appearances.
