Lazio had two players sent off as Inter Milan came from behind to win in Rome despite goalkeeper Etrit Berisha saving a penalty with his first touch.
Antonio Candreva put Lazio ahead before Mauricio was sent off for a foul on Rodrigo Palacio, with Hernanes scoring the free-kick against his former club.
Federico Marchetti was red-carded for a foul on Mauro Icardi, but Berisha dived low to stop the Argentine's spot-kick.
