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.
Napoli squeezed past 10-man Carpi thanks only to a Gonzalo Higuain penalty at the Stadio San Paolo as the match ended 1-0.
It proved to be a difficult match against 18th-placed Carpi in Naples and Maurizio Sarri's league leaders could have been usurped by Juve had Higuain not converted a 69th-minute spot kick.
Inter Milan came from two goals down to secure a point in a thrilling 3-3 draw against Hellas Verona.
Bottom-of-the-table Verona, who claimed only their first victory of the Serie A season against Atalanta on Wednesday, were behind after eight minutes when Jeison Murillo opened the scoring for Inter.
But the hosts were back on level terms moments later when Filip Helander scored from a corner before Eros Pisano stunned Roberto Mancini's side when he headed home Luca Marrone's free-kick with 16 minutes gone.
Verona led at the interval and then scored a surprising third when Artur Ionita netted from a corner.
Inter were facing an uphill challenge to take anything from the game, but gave themselves hope when Mauro Icardi converted Ivan Perisic's cross shortly after the hour mark.
Perisic then scored his side's equalising goal with 12 minutes left after good work from Rodrigo Palacio.
Roma resisted a late Sampdoria fightback to record a 2-1 victory at the Stadio Olimpico.
Goals from Alessandro Florenzi and new signing Diego Perotti boosted the Giallorossi into a healthy lead, but Fernando's response for Samp set nerves jangling.
Wojciech Szczesny had to protect the three points with a point-blank save from Antonio Cassano at the death.
Udinese checked AC Milan's rise up the table by holding the Rossoneri to a 1-1 draw at San Siro.
Former Rossoneri defender Pablo Armero made life difficult for Sinisa Mihajlovic's men, who had been pursuing a third straight win, with his first-half opener and Milan struggled to respond.
M'Baye Niang did fire an equaliser shortly after half-time but the hosts had missed an opportunity to close the gap on the nearest Champions League place to just four points.
Atalanta and Empoli shared the spoils from a disappointing goalless draw at the Stadio Atleti Azzurri d'Italia.
Neither side could trouble the scoreboard in rainy Bergamo, with both clubs left frustrated in their quests to secure overdue wins.
Atalanta edged the first half, with Alejandro Gomez blasting over the bar and Mauricio Pinilla shooting wide from a one-on-one with Lukazs Skorupski.
Empoli hit a post through Riccardo Saponara when play resumed, but Atalanta soon picked up their assault and were unlucky to miss the mark when Alessandro Diamanti intercepted a poor backpass from Mario Rui and let fly.
Ten-man Palermo held out for a point from a frenetic 2-2 draw at Sassuolo, while Valter Birsa fired Chievo to a 2-1 victory at Torino.
