MILAN (AP) — Fernando Llorente scored a stoppage-time winner to help Juventus snatch a 1-0 win over Udinese and stretch its lead at the top of the Italian league to three points after Roma drew 1-1 at Atalanta.
Roma also needed a late goal as Kevin Strootman scored in the final minute to preserve the team's unbeaten record.
Mario Balotelli's free kick helped AC Milan beat Catania 3-1 for its first win in six league matches, while a last-minute equalizer saw Sampdoria earn a 1-1 draw at Inter Milan, in front of new Nerazzurri President Erick Thohir.
Elsewhere, Cagliari came back from two goals down to draw 2-2 against Sassuolo and Chievo Verona beat Livorno 3-0.
Juventus dominated possession, but it was Udinese which had the best opportunities and home goalkeeper Gianluigi Buffon pulled off a three stunning saves to deny Antonio di Natale twice and Andrea Lazzari once.
Defender Stephan Lichtsteiner returned after almost two months out with an injury and he was instrumental in the Juventus goal flicking on a cross for Llorente to head past the motionless Zeljko Brkic.
Llorente had almost scored moments earlier but saw his header cleared off the line by Udinese defender Allan.
Kickoff had been brought forward to allow more than 12,000 children to fill the stands behind each goal, replacing the ultras which had been banned for insulting territorial chants against Napoli.
It was Juve's sixth successive league victory without conceding a goal.
"We have to continue like this," Juventus coach Antonio Conte said. "We have 12 wins, a draw and a defeat. That's very important but we mustn't sit back on our successes.
"We were good today and lucky. We played well and showed that we are doing well physically, despite playing three games in a week. Buffon was good today, but Brkick was exceptional."
Key playmaker Andrea Pirlo limped off after 13 minutes with a knee injury.
Earlier, Roma was held to its fourth successive draw.
Atalanta, which had hit the post in the first half, took the lead seven minutes after halftime when Davide Brivio sent a free kick under the wall and into the bottom right corner, although Roma goalkeeper Morgan De Sanctis was partly at fault as he misjudged the ball.
United States forward Michael Bradley thought he had leveled in the 76th but his header was harshly ruled out for offside.
Atalanta goalkeeper Andrea Consigli made several good saves, but could do nothing when Adem Ljajic crossed for Kevin Strootman to tap in from six yards.
There was also a last-gasp leveler at San Siro, where Thohir was watching his first match since being elected president last month. Inter captain Javier Zanetti made his first start since snapping his Achilles tendon in April.
