The party atmosphere at the newly renamed Stadio Olimpico Grande Torino was ruined by visitors Sassuolo who ran out 3-1 winners on Sunday afternoon.
Joel Obi, who was so impressive in the narrow defeat at Roma, was injured in the warm up so Afriyie Acquah started in his place.
The away side took the lead with only two minutes on the clock when Alfred Duncan's cross was headed home by Nicola Sansone.
However, Toro were level just five minutes later after a swift counter attack that was started by Daniele Baselli, and finished by Bruno Peres - who has now scored in consecutive home games.
Torino should have gone into the break in the lead, but Josef Martinez hit the bar when one on one with Andrea Consigli.
Andrea Belotti had Toro's best chance of the second half, but he blazed over the bar after good work from his strike partner Martinez.
And the Granata were made to pay for that miss when Domenico Berardi's corner was headed home by former Juve defender Federico Peluso with fifteen minutes remaining.
Sassuolo made the scoreline even more convincing with the last kick of the game, as former Fulham striker Marcello Trotta broke clear before finishing past Daniele Padelli.
