Roma maintained their 100 percent start to the Serie A season on a day when Napoli and Juventus also claimed three points, but AC Milan's disappointing season continued with a late defeat to Parma.
Substitute Michael Bradley ensured leaders Roma stayed perfect by sealing their ninth consecutive Serie A win as they saw off Udinese 1-0.
The capital club survived the challenge of ambitious Napoli last time out and faced another huge test in Udine, where they struggled for incision without injured captain Francesco Totti before losing Maicon to a red card midway through the second half.
That setback served only to spur Rudi Garcia's men on, however, and American midfielder Bradley emerged from the bench to beat Ivan Kelava, booking the Giallorossi a slender win and a haul of 27 points from the 27 available.
Two first-half Gonzalo Higuain penalties earned second-placed Napoli a 2-0 victory over Torino in Sunday's early kick-off.
Torino's players protested against both spot-kicks, the first given for a challenge on Dries Mertens and the second for handball against Kamil Glik, but to no avail and Higuain confidently slotted both home.
The win was Napoli’s seventh in nine games in Serie A under Rafa Benitez.
Juventus are level on points in third place after they beat Genoa 2-0 in Turin.
Goals from Arturo Vidal and Carlos Tevez secured the win in a match that marked a return to form for Juve, who lost at Fiorentina before suffering a Champions League defeat at Real Madrid in midweek.
They remain five points behind Roma, but this showing will go some way to reassuring coach Antonio Conte that his club can still achieve their aim of winning a third straight Scudetto.
The latest of late goals from Marco Parolo gave Parma a 3-2 win that fired them into the top half of the table as AC Milan's second-half comeback at the Stadio Ennio Tardini proved in vain.
The Gialloblu were good value for their half-time lead with both Parolo and Antonio Cassano cutting through a disorganised Milan team to score impressive individual goals.
But something clicked with the visitors over the break and, shortly after Alessandro Matri hit an overdue first goal for his new club, defender Matias Silvestre dragged Milan level with a header.
Massimiliano Allegri's men pushed hard for the winner but it would not come, Parolo instead grabbing the glory with a free-kick at the death.
Fiorentina capped a memorable week with a 2-1 victory at Chievo to stretch their unbeaten league run to four matches.
Bostjan Cesar fired the hosts in front at Stadio Marc'Antonio Bentegodi but two goals from Juan Cuadrado turned the result around for the Viola.
Bologna's unwanted record of being the only team in Serie A without a victory this season came to an end on Sunday as they defeated Livorno 1-0 to move off the foot of the table.
Stefano Pioli's men were without a league win since May 12, having lost five and drawn the other three of their opening eight games this season, but they were finally able to celebrate a three-point haul thanks to Jose Angel Crespo's early goal.
Catania and Sassuolo, two of Serie A's early strugglers, played out a goalless draw at the Stadio Angelo Massimino.
The home side had the majority of the chances but Sassuolo almost left with all the points only for Simone Zaza to miss an open net with four minutes left.
