Juventus kept in touch with Serie A leaders Napoli ahead of next weekend's Scudetto showdown in Turin by beating Frosinone 2-0 at the Stadio Matusa.
Second-half goals from Juan Cuadrado and Paulo Dybala saw the Bianconeri ensure Napoli remain only two points clear before visiting them on Saturday.
Juve dominated the first half but failed to score, with Stefano Sturaro blasting wide inside five minutes and returning after the half-hour mark to trouble Nicola Leali with a swerving attempt from the edge of the box.
On the stroke of half-time, Leali got the better of Alvaro Morata in a one-on-one and Juve's players appeared frustrated at the break.
The Bianconeri continued to struggle when play resumed and the near misses kept on coming. Paul Pogba was marginally offside when Leali's goal was at his mercy and substitute Roberto Pereyra soon blasted well wide.
But Juve kept turning the screw and their persistence paid off 17 minutes from time as Cuadrado made the breakthrough.
The on-loan Chelsea winger, who had just watched the tricky Dybala hit a post, collected Alex Sandro's short pass and fired the ball over Leali's shoulder to find the inside of the far post.
Cuadrado might have grabbed another goal to rubber-stamp the victory in the 84th minute, but he dragged his shot wide and had to leave that job to Dybala.
In stoppage time, the former Palermo forward brought up his 13th goal of the season with his left boot to confirm Juve's 14th consecutive victory.
