Torino secured their spot in the Italian top flight for next season with a goalless draw at Lazio on Tuesday, dooming Benevento to relegation.
Lazio were awarded a penalty in the 83rd minute, but Ciro Immobile's spot kick hit the post, saving Torino from a tricky trip to Benevento, who would have needed a win to stay in Serie A.
Filippo Inzaghi's Benevento side have 32 points with one game remaining and trail 17th-placed Torino, who they face in the last round of matches, by four points.
Lazio, managed by Inzaghi's brother Simone, stayed sixth on 68 points.
