Alvaro Morata and Gaetano Letizia both scored spectacular goals, while Wojciech Szczesny and Lorenzo Montipò also made excellent fingertip saves.
Juventus took the lead at the Stadio Vigorito when Federico Chiesa’s inspired cross-field pass found Morata for a control, shimmy and angled drive.
Szczesny kept Juve in front with a remarkable save at full stretch to push Pasquale Schiattarella’s effort out of the far bottom corner.
However, moments later he was unable to prevent a splendid Letizia volley on Arthur’s weak clearance.
Juve threw the kitchen sink at Benevento in the second half, with Montipò decisive in goal and Paulo Dybala off target, but Morata let the tension get to him with a red card after the final whistle for dissent.
