Torino largely dominated this match and secured victory with Antonio Sanabria and a double deflection, but Bologna left it too late before fighting back.
The Granata had Wilfried Singo back from suspension, but Andrea Belotti, Simone Verdi and Koffi Djidji still injured, with Rolando Mandragora not fully fit. Bologna had Nico Dominguez out on a ban, with Jerdy Schouten sidelined.
Sasa Lukic and Roberto Soriano had efforts from distance, but Lukic robbed Andreas Skov-Olsen in midfield, the through ball sending Antonio Sanabria clear to beat Lukasz Skorupski one-on-one.
Skorupski was at full stretch to palm a deflected Lukic effort round the post, while Adama Soumaoro risked an own goal on the Tommaso Pobega pull-back.
Sanabria’s strike bounced off the crossbar on the stroke of half-time, as it was one-way traffic in Turin.
Skorupski was decisive in a one-on-one situation with Sanabria, palming the ball off his feet, while Aaron Hickey’s curler flashed just wide.
Torino finally doubled their lead in chaotic fashion, as Lukic pulled back from the by-line for Tommaso Pobega from eight yards, his finish was going wide until a double deflection off Adama Soumaoro and Skorupski.
Bologna were awarded a penalty when Nicola Sansone burst into the box and went down, although contact with Vanja Milinkovic-Savic seemed minimal at best. Nonetheless, Riccardo Orsolini blasted the spot-kick into the roof of the net.
Moments later, Marko Pjaca had penalty appeals waved away for what seemed to be a Nicolas Viola trip, but Bologna began to believe and push only in the final minutes.
Simone Zaza almost made it 3-1 in stoppages, a sensational Skorupski save on Simone Zaza from point-blank range.
