ROME - Juventus winger Mauro Camoranesi fired home a 77th-minute equaliser to deny arch-rivals Internazionale a vital three points on Sunday night.
A match billed as the biggest in Serie A so far this season seemed to be heading the way of the Serie A leaders when Julio Cruz put them in front four minutes before half-time.
But substitute Camoranesi grabbed a leveller with 13 minutes to go to frustrate the Nerazzurri, whose lead at the top of the standings was cut to two points over the weekend following Fiorentina's 1-0 win at Lazio on Saturday night.
Giampaolo Pazzini grabbed the Viola's winner after 19 minutes at the Stadio Olimpico.
Roma missed the chance to go second after squandering a 2-0 lead at Empoli.
The Giallorossi looked in an unassailable position at half-time thanks to goals from Ludovic Giuly and Matteo Brighi.
But the struggling hosts, and striker Ighli Vannucchi in particular, launched a fightback which was as impressive as it was unexpected.
Vannucchi reduced the arrears midway through the second half and substitute Sebastian Giovinco snatched a last-gasp equaliser to deny the Romans.
Fifth-placed Udinese survived some anxious moments before extending their unbeaten run to eight games with a goalless draw at Livorno while Atalanta are up to sixth thanks to a 2-1 win at Catania.
Cristiano Doni missed a penalty for the visitors in a goalless first period, but they seemed to be cruising to victory after two strikes in as many second-half minutes from Antonio Langella.
Gionatha Spinesi brought the Sicilians back into the game with eight minutes remaining but they could not find an equaliser.
Reggina came within seconds of registering their first win of the season - and handing new coach Renzo Ulivieri a debut win - only to be foiled at the death by Napoli's Ezequiel Lavezzi.
The struggling Amaranto had taken a 55th-minute lead through Luca Vigiani's header.
And with Reggina goalkeeper Andrea Campagnolo saving a 75th-minute penalty from substitute Emanuele Calaio, the visitors looked on course for their first success of what has been an awful season so far.
But Lavezzi struck just before the end to keep the Calabrians firmly rooted to the bottom of the table while Napoli climb to seventh.
Genoa were pegged back twice by Palermo as the two sides shared six goals at the Luigi Ferraris Stadium.
The visitors were ahead after eight minutes through Edison Cavani and veteran goalkeeper Alberto Fontana kept the home side out until the 58th minute, when a Leon free-kick brought them level.
Leon put the home side ahead for the first time in the 65th minute, but Franco Brienza levelled matters 10 minutes later.
Marco Borriello thought he had won the game for Genoa in the 81st minute, but a header from Amauri in the last minute meant Palermo left with a point, thanks mainly to their irrepressible goalkeeper.
Sampdoria won 3-0 at Cagliari thanks to first-half goals from Sergio Volpi, Andrea Caracciolo and Christian Maggio. The visitors did have Mirko Pieri sent off in the 68th minute, however.
Daniele Galloppa's late equaliser earned strugglers Siena a 2-2 at Parma.
Saturday's other game saw AC Milan fail to register their first Serie A win at the San Siro this season as they played out a goalless draw with Torino.
