The league's top three all enjoyed successful outings on Sunday, with Juve marking Antonio Conte's 100th Serie A match in charge of the club with a 3-1 home win over Chievo.
The reigning champions won under coach Conte for the 70th time in the league to continue their perfect record at Juventus Stadium in the league this season.
Conte's side controlled the first half, which was highlighted by Kwadwo Asamoah's stunning goal in the 17th minute.
Claudio Marchisio tapped in to double Juve's lead, although Chievo equalised in bizarre circumstances, as Stephan Lichtsteiner's clearance hit Martin Caceres and went in.
Juve had let a two-goal lead slip against Chievo's local rivals Verona last week, but Llorente's 57th-minute header calmed nerves and sealed the result.
Mattia Destro made the most of a rare start to score a double for the capital club, who bounced back from Wednesday's Coppa Italia exit at Napoli in perfect fashion.
Destro opened the scoring on the stroke of half-time and Roma doubled their lead nine minutes after the break thanks to Miralem Pjanic's excellent free-kick.
The day's best comeback saw Genoa dig deep in front of their home fans to salvage a point in a thrilling encounter.
Dusan Basta and Bruno Fernandes put Udinese 2-0 ahead, and although Moussa Konate responded in first half stoppage time, Luis Muriel's penalty just after the break looked to have sealed the result for Francesco Guidolin's side.
