Juventus used two late goals to beat Torino 2-0 in the Derby della Mole on Sunday as the defending champion inched closer to its 29th Serie A title.
Arturo Vidal scored three minutes from time to give Juventus the victory, shortly after Torino had been denied what looked a clear penalty. Torino defender Kamil Glik was then sent off in the final minute before Claudio Marchisio sealed the result.
Antonio Conte's team is 11 points ahead of second-place Napoli and can secure the title against Palermo next weekend.
"It's the most important goal I've scored since I've been here," Vidal said. "Now we're really so close to winning the title.
"It was a difficult game, Torino plays very well. What's important though is that at the end we won. We only need a point, now we have to think about the match against Palermo."
AC Milan remained third in the battle for the last Champions League spot, as substitute Giampaolo Pazzini scored twice in as many minutes to help his team fight back to a 4-2 win against Catania.
The team is a point ahead of Fiorentina, which beat Sampdoria 3-0.
Elsewhere, Pablo Daniel Osvaldo scored a hat trick to help Roma to a 4-0 win over struggling Siena, which slipped into the relegation zone after Palermo beat Inter Milan 1-0.
Mirko Vucinic should have opened the scoring for Juventus in the 11th minute when he beat the offside trap to run onto Paul Pogba's through ball, but he misfired and his effort rolled wide. Vidal also had a chance shortly after but headed over.
Juventus was getting stronger and Pogba almost fired into an empty net before Glik made a decisive block. Torino almost took the lead on the stroke of halftime as Mario Santana forced goalkeeper Gianluigi Buffon into a diving save.
There was more of the same in the second half as Torino continued to frustrate Juventus.
Torino hadn't scored in the past seven derby matches but could have done so late on. Alessio Cerci flashed the ball across the face of goal and Jonathas was prevented from connecting with it in front of an empty net as his shirt was being held by Leonardo Bonucci.
Torino's appeals for a penalty were waved away and Juventus took the lead when Vidal fired a shot just inside the left post from 20 meters.
Meanwhile, Roma moved into fifth and boosted its chances of a Europa League spot. It is two points above seventh-place Inter.
Roma doubled its lead less than two minutes later, Lamela slotting home following a delightful chip over the defense by Francesco Totti.
Osvaldo hit the post, before doubling his tally four minutes from the interval. Alessandro Florenzi did well to win the ball near the deadball line, and he cut it back to Osvaldo, who fired it into the bottom left corner.
The Italy striker completed his hat trick midway through the second half. Totti's shot was saved by Pegolo, but the ball escaped from his grasp and Osvaldo rushed forwards to tap it into an empty net. Palermo got off to a bright start against Inter and could have taken the lead in the seventh minute but goalkeeper Samir Handanovic did well to smother Fabrizio Miccoli's volley.
The Sicilian side took the lead just three minutes later when former Palermo defender Matias Silvestre gifted the ball to Miccoli, who poked it through for Josip Ilicic to score his fifth goal in as many games.
Matters got worse for Inter when captain Javier Zanetti was carried off on a stretcher. It was later confirmed he tore his Achilles tendon and now faces a six-nine month layoff.
Zanetti turns 40 in August and there are fears that the injury could spell the end of his career.
"I don't know exactly what happened but at a certain point I felt a pull and it really hurt so much. It still does," Zanetti said. "I will overcome this, too." Elswhere, Lazio defender Giuseppe Biava was sent off for a second booking in stoppage time as the capital club drew 0-0 at Parma.
