| Sebastiano Siviglia scored against his former Atalanta teammates for Lazio's second straight win. Biancocelesti boss Delio Rossi, Luciano Zauri, Sebastiano Siviglia and Stephen Makinwa faced their former club at the Olimpico in what has become a relegation dogfight in the wake of their 11-point Calciopoli penalty. Atalanta were without Cristiano Doni, Christian Vieri and Moris Carrozzieri, who begins a two-month ban for illegal betting.
Nicola Ventola skipped past Guillermo Stendardo, but his angled drive was well held by Marco Ballotta. The goalkeeper was standing in for Angelo Peruzzi, who has a wrist injury.
Riccardo Zampagna nodded a Ventola cross off target, while Pasquale Foggia set up Massimo Oddo for a well-saved finish.
Alex Calderoni performed a desperate double save on 37 minutes. A free kick was floated into the six-yard box, where the Atalanta goalkeeper parried first Stendardo's attempt and then the Tommaso Rocchi follow-up.
Rossi threw on former Atalanta striker Makinwa for the second half and it livened the team up. Rocchi wasted a good opportunity and Stefano Mauri fired over from the edge of the area.
However, Makinwa suffered an injury and limped off eight minutes later to make way for Igli Tare.
Rocchi thought he'd given Lazio the lead, but his long-range strike cannoned off the underside of the bar and bounced back out off the ground without crossing the line.
Calderoni was again crucial with a double save on Oddo's missile of a free kick.
The deadlock was eventually broken from a set-piece. A free kick was touched on by Tare for ex-Atalanta man Sebastiano Siviglia to volley in at the back post.
Loria had the best opportunity to equalise on his return from a long-term injury, but couldn't quite get on the end of the assist to beat Ballotta.
