Elsewhere in Italy, Torino came out on top in a five-goal thriller against basement boys Siena, while fellow strugglers Bologna thrashed Chievo to end their recent run of defeats
Bologna ended a run of two straight defeats in style after they sailed to a 4-0 success against an in-form Chievo on Saturday.
Inside just 13 minutes, Panagiotis Kone evaded his marker to open the scoring with a header from a corner.
They doubled their lead on the cusp of half-time when Diego Perez dispossessed Cyril Thereau in midfield to launch a counterattack for Alberto Gilardino to finish off with a lob over the goalkeeper.
On the hour mark, Gilardino bagged his second goal of the match via another Alessandro Diamanti corner, and if it was not already apparent, the Flying Donkeys saw Alberto Paloschi's strike chalked off due to handball.
The rout was completed late on as Manolo Gabbiadini stole the show with a fine solo effort to lift the Rossoblu to 14th in the table. Chievo, meanwhile, stay in 11th place.TORINO 3-2 SIENA
In Sunday's early kick-off, Torino and Siena fought a five-goal thriller but it was the hosts who eventually prevailed, beating the Tuscans 3-2.
Alessio Cerci's fifth-minute cross was met by Matteo Brighi, who arrived late in the box to smash open the deadlock.
But soon after, the Granata's failure to avert danger in their own half was paid for when Reginaldo made it two goals in as many matches, scrappily equalising from close range.
On 38 minutes, Torino went back ahead through Rolando Bianchi. The former Manchester City striker netted a free header from Valter Birsa's cross.The points were sealed in first-half injury time when Cerci capped off an impressive display, hitting Siena on the break before guiding the ball around Gianluca Pegolo and into an empty net.
And even if the visitors did pull one back with 15 minutes to go thanks to journeyman striker Michele Paolucci meeting Reginaldo's flick-on at the far post, Torino move to 12th. Siena, however, remain rooted to the bottom, eight points adrift.
The visitors did get one back with 15 minutes to go after Cerci sluggishly gave the ball away in the final third, allowing a Cristiano Del Grosso cross that Reginaldo knocked down for Paolucci’s finish at the back post.
LAZIO 2-0 ATALANTA
Lazio closed the gap at the Serie A summit to just three points after they eased to a comfortable 2-0 victory over Atalanta on Sunday.
Sergio Floccari opened the floodlights midway through the second half against his former club, albeit with a hint of luck as he appeared to have used his hand in the build-up to the strike.
Ten minutes later, Stefano Mauri's cross was turned in by Orobici defender Davide Brivio to hand the Romans a fifth straight win and consolidate their grip on second place.
For Atalanta, who also had to contend with Carlos Carmona's red card, they have now gone five matches without a win, including four defeats in that spell, and fall to 13th.
UDINESE 3-1 FIORENTINA
Fiorentina risk falling into a mid-season slump after their 3-1 defeat to Udinese was their second in as many matches.
The Viola did take the lead, however, when Gonzalo Rodriguez's header deflected goalbound via the shoulder of Serbian goalkeeper Zeljko Brkic.
But right on the edge of half-time, Giulio Migliaccio's foul on Maurizio Domizzi in the box allowed Antonio Di Natale to hammer home the equaliser from the penalty spot.
Twenty minutes after the restart, the Zebrette grabbed a double-goal salvo when firstly, Andrea Lazzari - against his old team - crossed into the area for Di Natale to put his side in the driving seat.
There were suspicions that the veteran striker was offside, but there was no doubt about Luis Muriel's angled drive a minute later.
Udinese are now unbeaten in their last five Serie A matches, winning three of them, and move up to eighth in the table. Fiorentina, however, drop to fifth following Inter's victory over Pescara.
CAGLIARI 2-1 GENOA
Genoa's mini-revival came to a sour end on Sunday, as Cagliari - in a rut of their own - came back from behind to record a 2-1 win in Sardinia and end a pattern of five straight losses.
New signing Eros Pisano scored from a corner to hand the Ligurians the lead early in the second half, but on 55 minutes, Marco Sau made it three goals in his last four games, beating Sebastian Frey from a counterattack.
And with just eight minutes remaining, Daniele Conti's header turned the game on its head as Cagliari climb out of the bottom three at the expense of Genoa - who also had Felipe Seymour sent off.
NAPOLI 3-0 PALERMO
Napoli are determined not to look back this season, and their 3-0 success over Palermo made it three wins on the bounce for the Partenopei.
On the half-hour mark, Marek Hamsik's corner diverted onto the head of Christian Maggio, and the right-sider grabbed a vital goal in his quest to keep his place in the side following Pablo Armero's recent arrival from Udinese.
Just four minutes later, Gokhan Inler played a neat one-two with the Slovak before rifling home a pile-driver from distance to make it 2-0 to Napoli.
And in the latter stages of the second half, the Switzerland midfielder drilled the ball into the middle of the box for Lorenzo Insigne to drive into the corner of the net.
Napoli stay two points behind Lazio but remain in third. Penultimately-placed Palermo, however, had no reply for the southern Italians and have now lost six of their last matches.
CATANIA 1-0 ROMA
Catania put a stop to their sequence of three games without victory by condemning Roma to a 1-0 defeat at the Angelo Massimino.
Giallorossi boss Zdenek Zeman sprung a surprise with his team selection, as midfielder Marquinho was drafted in from the periphery to start in attack alongside Mattia Destro and Erik Lamela, while Leandro Castan was given the nod ahead of Marquinhos at the back.
With neither Francesco Totti nor Pablo Osvaldo starting, Roma naturally had much of the ball in the midfield areas but their lack of penetration soon became evident, as they could not break down the Sicilian resistance.
It gave Catania the perfect opportunity to bolster their reputation as a bogey team of the visitors, and they did not look back when Gonzalo Bergessio's lay-off was tucked home by Alejandro Gomez, who scored yet again at the capital side's expense.
The Elefanti stay in 10th place, but Roma, in sixth, fall eight points behind third-positioned Napoli.
