Elsewhere in Italy, Fiorentina found three second-half goals to defeat Cagliari, while Napoli dropped more points to Torino and Antonio Di Natale spared Udinese's blushes again
|Parma's run of three straight victories came to an abrupt end as they fell to defeat at Pescara in Sunday's early Serie A kick-off.
The pressure had been mounting on Delfini boss Giovanni Stroppa following a run of three losses in four matches and a goal drought in that sequence, but the former Italy midfielder looks to have been given a stay of execution.
The hosts broke their duck shortly after the restart - Elvis Abbruscato pounced on a long ball, which Gabriel Paletta failed to address, and fired low and hard past Antonio Mirante.
Roberto Donadoni's side went desperately searching for an equaliser, but it came at a cost. With just seconds remaining, Vladimir Weiss exploited space at the back and struck a shot which fizzed in off the post.
Pescara move out of the relegation places and into 14th, but Parma drop to eighth spot.
|Udinese were again forced to come back from behind to register a result, as they drew with Bologna at the Dall'Ara.
The hosts took the lead just a minute into the second half through Alessandro Diamanti, who met Manolo Gabbiadini's drilled pass in the box. It was the Italy international's third goal of the season.
However, Antonio Di Natale was once more the Zebrette's saviour, taking advantage of a cross that deflected into his path before smashing the ball on the half-volley into the net.
Francesco Guidolin's charges are now unbeaten in four league matches and find themselves in 11th. Bologna's rotten run of four straight defeats may have now been halted, but they continue to languish near the bottom.
|Lazio's poor run of form - since beating AC Milan a couple of weeks ago - continued as they were swept aside by the sizzling Sicilians.
Alejandro Gomez kicked off Catania's memorable afternoon with a superb finish on nine minutes, coming in from the left-hand side and unleashing an unstoppable drive past Albano Bizzarri.
Twenty-five minutes in and Andre Dias' handball in the box presented Francesco Lodi the chance to double his side's lead from the penalty spot. He did just that, sending the Argentine goalkeeper the wrong way.
Moments later, the victory was effectively wrapped up - again via the left flank - as Giovanni Marchese's cross was flung in by Gomez, despite Biancocelesti attempts to clear the ball off the line.
The winger's sensational afternoon was capped off with a terrific counter-attack, leaving Abdoulay Konko for dead before rolling the ball into the path of Pablo Barrientos for a simple tap-in.
Catania's run of three games without a win is now over and they move to seventh. Lazio, meanwhile, fall behind Fiorentina in fifth spot.
|Fiorentina's fortunes under Vincenzo Montella seem to be improving by each passing matchday after they cruised to victory over Cagliari on Sunday.
First blood went to the Viola via Gonzalo Rodriguez, who headed home former Villarreal team-mate Borja Valero's corner. However, the Sardinians equalised in controversial fashion through Federico Casarini's deflected strike on half-time.
Albin Ekdal had been standing in an offside position as the midfielder took his shot but was not adjudged to have interfered with play, as Facundo Roncaglia had the final touch. Yet, there wasn't such confusion for Stevan Jovetic's goal on 50 minutes.
The Montenegrin hit a half-volley from close range after Cagliari failed to clear their lines from a corner, and he set up Luca Toni for the third of the match, and his third of the season, rounding off a lightning-quick break.
Juan Cuadrado sealed an emphatic win for Fiorentina, who now displace Lazio in fourth position. The visitors' run of four straight wins, latterly, have now reached an impasse and fall to 12th.
|Napoli's poor run of late continued on Sunday as they were held to a dramatic draw at home to Torino, leaving them with a record of just one win their last five games.
Edinson Cavani marked his return to the starting XI with a goal inside seven minutes following a diverted cut-back from Marek Hamsik.
However, the Granata were good value for their point and netted a deserved leveller in the first minute of injury time - Salvatore Aronica's misjudged back-pass was guided in by Gianluca Sansone.
The hosts stay third in Serie A but are now four points behind second-placed Inter. Torino, meanwhile, lie in 13th.
|Atalanta moved clear of the relegation zone after beating Sampdoria 2-1 at the Marassi - a result which extends the Blucerchiati's wretched run of league defeats to six matches.
Ciro Ferrara's side initially enjoyed life on their return to the Italian top flight, winning three and drawing two of their first matches, but the former Juventus and Italy defender's position at the helm looks to be under increasing pressure.
The Orobici claimed the initiative just two minutes into the action via Giacomo Bonaventura, who connected with Maxi Moralez's cross.
However, Sampdoria seemed to have found some solace in Enzo Maresca's sensational overhead kick on 53 minutes, which levelled the contest.
It was not to be the home side's day, though, as Giuseppe De Luca, at full stretch, slid home German Denis' pass from the left flank to hand Atalanta all three points.
They move into the top half of the table in ninth place, but Sampdoria flounder in 15th spot.
|Siena moved three points closer to survival in Serie A after inflicting a 1-0 reverse on Genoa, who have now lost their last four matches successively.
The appointment of Luigi Del Neri at the Marassi has not had the desired effect on the club's results, and a recent backlash from supporters - due to the perceived negative football being played - has not helped matters.
The winning goal came on 55 minutes, as Francesco Valiani's corner was headed in by Massimo Paci to secure all of the spoils and hand coach Serse Cosmi a victory over his former employers.
The Tuscans remain bottom but are now just three points behind the Ligurians, who are 17th in the table.
|Roma bounced back from two consecutive losses in clinical fashion after condemning Palermo to a 4-1 defeat at the Olimpico to wrap up the weekend's action in Italy.
Zdenek Zeman's Giallorossi have recently come in for criticism due to their tendency to leak goals, with leads against Udinese and Parma being squandered but there was to be no such scenario this week.
Eleven minutes in, Ivan Piris' corner found Francesco Totti, who netted the rebound from his saved header. Later in the first half, Pablo Osvaldo made it 2-0 following Ezequiel Munoz's collision with Samir Ujkani.
Midway through the second period, Panagiotis Tachtsidis' lay-off found Erik Lamela for his seventh goal of the season, and the Argentine supplied the through-ball for Mattia Destro to complete the rout late on.
The summer arrival from Siena grabbed his first Roma goal when he dribbled around Ujkani, but he was subsequently sent off after being shown a second yellow for taking his jersey off while celebrating.
Josip Ilicic did conjure up a consolation strike for the Rosanero at the death, but they remain 19th. The hosts, however, move back up to sixth in the standings.
