Milan fails to capitalise

Hugo Campagnaro put a lively Napoli ahead in the 13th minute, but Filippo Inzaghi equalised 12 minutes later at San Siro.

Relegation-battler Atalanta gave its fight for survival a boost with a 3-0 victory over fellow struggler Livorno, who are now bottom of the table.

Simone Padoin set the Bergamasco on the way with the opening goal after 13 minutes and further strikes from Javier Chevanton and Adriano Ferreira Pinto early in the second half sealed matters.

Andrea Masiello scored five minutes from time to grab a 1-1 draw for Bari at home to Parma.

The visitors were fortunate to take a 36th-minute lead after Nicola Belmonte turned the ball into his own net following a cross by Damiano Zenoni but Masiello salvaged the draw.

Lazio secured only its third away win of the season to move four points clear of the relegation zone as Cagliari's woeful run continued.

First-half goals from Tommaso Rocchi and Sergio Floccari clinched a 2-0 triumph for the capital club, who move to 29 points from 29 games as a result.

Siena put new life into its battle to avoid the drop with a hard-fought 1-0 win over Bologna.

Alberto Malesani's men are now unbeaten in six Serie A games although fourth-bottom Lazio's win at Cagliari means they remain four points from safety after Argentinian Marcelo Larrondo grabbed the only goal for Siena.

Chievo paid the price for its profligacy in front of goal as Maxi Lopez's penalty ensured Catania snatched a 1-1 draw in the relegation six-pointer at the Stadio Marc'Antonio Bentegodi.

The hosts wasted a plethora of chances before Sergio Pellissier eventually gave them the lead in the 64th minute but Lopez scored his third goal in as many games to ensure Catania made the long trip back to Sicily with a point.

Antonio Cassano got the only goal after 77 minutes as Sampdoria climbed above Juventus to fifth in the table with a 1-0 win in the evening game.
