MILAN (AP) Sassuolo, Palermo and Torino all dropped their first points of the season to leave Inter Milan as the only Serie A team still with a perfect record ahead of Sunday night's eagerly anticipated derby match against former player Mario Balotelli and AC Milan.
All four of the afternoon matches ended with the same 2-2 scoreline. Sassuolo drew at home to Atalanta, in a match that also saw two saved penalties and two red cards, while Torino drew at Hellas Verona.
Newly promoted Carpi picked up its first ever Serie A point at Palermo, while Napoli coach Maurizio Sarri's return to Empoli also ended in a stalemate.
Sampdoria's home match against Bologna was postponed due to bad weather and will be played on Monday at 1845 GMT.
Lazio hosts Udinese later.
Sassuolo was looking to maintain its perfect start to the season and it seemed set to do just that when it was awared a penalty in the sixth minute after Nicolo Cherubin brought down Simone Missiroli but Atalanta goalkeeper Marco Sportiello saved Nicola Sansone's penalty.
The teams produced a thrilling first half with Mauricio Pinilla scoring two goals for Atalanta, including a skillful overhead kick. Sassuolo twice leveled with long-range strikes from Francesco Magnanelli and Antonio Floro Flores to send the teams in level at the break.
Pinilla went from hero to villain at the start of the second half when he was shown a second yellow card for a poor challenge from behind on Federico Peluso.
However, Atalanta held on and could have won the match five minutes from time when Sime Vrsaljko tripped Maxi Moralez as he burst into the box. The Sassuolo defender was dismissed for his second yellow card in the space of a few minutes but Andrea Consigli saved Moralez's spot-kick to spare his teammate's blushes.
Palermo had yet to concede a goal this season but gave two to Carpi after taking a sixth-minute lead when Oscar Hiljemark tapped in Robin Quaison's deflected cross.
Palermo defender Roberto Vitiello turned Jerry Mbakogu's cross-shot into his own net for the equaliser before Marco Borriello scored his first goal in two years 20 seconds into his debut.
As Carpi was preparing to celebrate a first Serie A win, Uros Djurdjevic headed in Achraf Lazaar's cross to draw Palermo level two minutes from time.
