Sinigaglia had made over 200 games in Lega Pro but only a handful of games in Serie A and Serie B.
Sinigaglia was a youth product of Internazionale. He played his first Serie A match on 7 February 1999, Inter 5–1 Empoli. He was a substitute of Nicola Ventola. Coach Mircea Lucescu never used Sinigaglia again due to his young age.
Sinigaglia was jointly contracted with Ternana and Inter from 2001–02 season until June 2003; Ternana bought Sinigaglia and Cristian Lizzori outright from Inter for a peppercorn of €500 each that month.[nb 1] Ternana bought half of Sinigaglia and Lizzori for a total of 1 billion lire (€516,457) in July 2001 and June 2002 respectively.
Sinigaglia were loaned to Serie C1 and Serie C2 teams during his whole contract with Ternana, namely Veneto club Padova and Lombard club Monza. Sinigaglia was then joint owned by Ternana and Lumezzane. Sinigaglia scored his career high of 15 goals for the Lombard club in 2003–04 Serie C1. In June 2004 the co-ownership was renewed. On 31 August 2004 he was signed by Arezzo outright, from both Lumezzane and Ternana.
He played his first ever Serie B season for Arezzo in 11 games, before moving on loan to Atalanta of Serie A in January 2005 as a player to avoid fall back to the second division. He was then loaned by Genoa in 2005, to help the club to win promotion back to Serie B. He was called back in January 2006, for a chance to get the ticket of promotion playoff to Serie A for Arezzo, but failed.
Sinigaglia made 56 appearances in the third tier for Novara. Both seasons the club failed to win major trophy nor promotion to the second division.
In 2009, he was swapped with Simone Motta of Cesena, the newcomer of Serie B. Sinigaglia was valued €500,000 and Motta for €720,000 (thus only €220,000 cash was involved). Sinigaglia signed a 2-year contract. In his third Serie B season, he only scored once in 7 games. In January 2010 Sinigaglia was loaned to Lanciano of the third tier. Lanciano finished as the ninth of group B. In the same month Cesena promoted to Serie A as the runner-up. Sinigaglia did not have any chance in 2010–11 Serie A, his fourth Serie A season.
