Torino rode their luck on several occasions and thanked Salvatore Sirigu, but stunned Benevento in stoppages with Iago Falque.
Salvatore Sirigu was the busier of the two goalkeepers at the Stadio Vigorito.
However, while the hosts wasted several promising counter-attacks and scoring opportunities, the Granata forwards were more clinical.
Deep into injury time, Adem Ljajic sent Iago Falque clear with an inspired assist for the 1-0 victory.
Benevento suffer a third straight defeat, but have certainly not been lucky so far in their maiden Serie A season.
