Aiming for a record-extending eighth straight league title, Juventus set a record of 53 points at the season's halfway mark with 17 wins, two draws and no defeats.
ROME — Cristiano Ronaldo scored twice as runaway leader Juventus escaped with a 2-1 win over Sampdoria in Serie A on Saturday with help from the VAR.
Ronaldo's second goal, a penalty, was awarded by the VAR for a questionable handball. Then Sampdoria had a stoppage-time goal chalked off by the Video Assistant Referee.
Sampdoria thought it had become the first visiting Serie A club to score more than one goal at the Allianz Stadium in more than a year when Riccardo Saponara's shot went in off the underside of the crossbar, but replays showed the play was offside.
''I like (the VAR) a lot because it reduces the number of mistakes,'' Ronaldo said. ''It's not easy for the match officials to analyze everything that goes on. We just have to let them get on with their jobs.''
Ronaldo had put Juventus ahead two minutes in with a bouncing shot and Fabio Quagliarella equalized with a penalty before the break to become the first player to score in nine consecutive Serie A matches since David Trezeguet accomplished the feat with Juventus in 2005.
Ronaldo's decisive penalty came in the 65th after the VAR decided that Alex Ferrari had used his arm, even though it appeared as if the defender kept his arm next to his body and didn't move it toward the ball.
The double gave Ronaldo 14 goals in 19 matches this season to move one ahead of Genoa's Krzysztof Piatek atop the league scoring chart.
Ronaldo has maintained his form since leaving Real Madrid in the offseason, despite being the subject of a rape allegation in the United States.
Kathryn Mayorga filed a civil lawsuit in Nevada in September claiming Ronaldo raped her in his Las Vegas hotel room in 2009. Police reopened an investigation into the allegation at her request. Ronaldo has denied any wrongdoing.
Aiming for a record-extending eighth straight league title, Juventus set a record of 53 points at the season's halfway mark with 17 wins, two draws and no defeats. The Bianconeri remained nine points ahead of second-placed Napoli, which beat Bologna 3-2, and 14 points ahead of third-placed Inter Milan, which won 1-0 at Empoli.
''The first half of the season has gone really well,'' Ronaldo said. ''We've won nearly all our games and we're a solid side but there's still a long way to go. We must stay focused and keep working away if we want to achieve great things.''
Lazio remained fourth following a 1-1 draw with Torino in which both sides finished with 10 men. Sergej Milinkovic-Savic scored the equalizer for Lazio after a penalty from Andrea Belotti.
Roma won 2-0 at Parma with second-half goals from Bryan Cristante and Cengiz Under to move up to fifth, two points from the Champions League places.
Josip Ilicic came off the bench to score a hat-trick in Atalanta's 6-2 win at Sassuolo. It was Ilicic's third hat trick in 2018—matching Lionel Messi and Sergio Aguero for the record in Europe's top five leagues.
Udinese won 2-0 against Cagliari with goals from Ignacio Pussetto and Valon Behrami. Cagliari goalkeeper Alessio Cragno saved a penalty from Kevin Lasagna. Both teams ended with 10 men.
Emanuele Giaccherini scored with a curling free-kick as last-place Chievo Verona beat 10-man Frosinone 1-0 for its first win of the season.
Genoa and Fiorentina shared a 0-0 draw.
