Napoli kept up their pursuit of a place in next season's Champions League by beating relegation-threatened Novara 2-0.
Edinson Cavani and Paolo Cannavaro scored the goals in a one-sided Serie A game which was all over by half-time.
Chances were few and far between for Novara, who now lie 11 points from safety with only five games remaining. Walter Mazzarri's side, meanwhile, are just three points behind third-placed Lazio.
Catania boosted their hopes of clinching Europa League football next season with an impressive 2-0 victory over Atalanta.
Alejandro Gomez set the hosts on their way with the opening goal after half an hour and Felipe Seymour made sure of the points five minutes from time.
The win marked a return to winning ways for Vincenzo Montella's side, who had lost some team in recent weeks after a fine campaign, and lifted them within four points of fifth-placed Roma.
Parma took a stride away from the Serie A relegation zone thanks to a 3-0 win over Cagliari, who sit just four points above the bottom three with five games remaining.
Sebastian Giovinco was the orchestrator of Parma's win with the opening goal in the 24th minute and a hand in all of Parma's attacks.
The home side's second and third goals both came from the penalty spot, with Sergio Floccari scoring the first in the 73rd minute and Stefano Okaka wrapping up victory in the last minute.
Udinese missed the chance to pile the pressure on third-placed Lazio as they were held to a frustrating 0-0 draw by Chievo.
With the Roman club not in action until Sunday, a win would have put the Bianconeri up into the automatic Champions League places overnight. They were unable to deliver, though, and would not even have taken a point had Cyril Thereau not missed a first-half penalty for the home side.
It was an emotional evening for Udinese, taking to the field for the first time since the death of Piermario Morosini - their midfielder who had been out on loan at Livorno.
