Carlos Tevez became the joint-top scorer in Serie A this season as he fired runaway leaders Juventus to a win at 10-man Catania.
The former Manchester City striker scored his 16th of the season low into the net on the hour to restore his side's 14-point lead at the top.
Bottom-of-the-table Catania had striker Gonzalo Bergessio sent off for a foul on Giorgio Chiellini.
Roma had cut the points gap at the top to 11 on Saturday by winning at Chievo.
AC Milan earlier drew 1-1 at Lazio to end a four-match losing streak.
With striker Mario Balotelli dropped to the substitutes bench, Milan took the lead just before half-time through an Abdoulay Konko own goal, while Alvaro Gonzalez drew Lazio level just after the hour mark.
