MILAN — Inter Milan was at the wrong end of a penalty decision for the second week in a row Sunday, losing 2-0 at Cagliari after succumbing 4-3 to Atalanta in the previous round. Genoa and Sampdoria drew 1-1 in their derby and a blunder by Palermo goalkeeper Stefano Sorrentino, who appeared to forget the back pass rule, cost the relegation-threatened Sicilians a precious win against Bologna in another 1-1 draw. Cagliari's Mauricio Pinilla won and converted a 63rd minute penalty after he was caught by Matias Silvestre in what appeared a harsh decision and the Chilean also scored the second to hand Inter its fourth defeat in five league matches. Inter dropped to seventh with 50 points from 32 games. A speculative cross-shot by Matuzalem in the 80th minute gave Genoa a point against Sampdoria, who had taken the lead with a free kick by Brazilian Eder. Sampdoria had Andrea Costa sent off for a second bookable offense just before the equalizer. Palermo went ahead with a fourth minute goal by Josip Ilicic but Bologna levelled in bizarre circumstances. Sorrentino moved to pick up Michel Morganella's back pass, changed his mind, the ball went underneath him and Manolo Gabbiadini tapped into the empty goal. Palermo and Genoa stayed level on 28 points in the relegation zone, two behind Siena and safety. Pescara is bottom with 21. Luis Muriel scored twice to help Udinese to a 3-0 win at Parma in a mid-table clash and Erik Lamela struck on the hour as AS Roma won 2-1 at Torino to go sixth with 51 points. Chievo drew 0-0 with Catania as it all but secured its safety in Italy's top division. — Agencies
