Gonzalo Bergessio scored and Catania hit the woodwork twice, but were unable to beat 10-man Cagliari in a 1-1 draw.
This was a relegation dogfight, though the Sardinians had a seven-point buffer between them and the drop zone, while Catania had been revived since Rolando Maran returned to the bench and climbed to penultimate place. Giuseppe Bellusci was suspended for the hosts, while Adryan and Victor Ibarbo were injured for the visitors.
Mariano Andujar needed a save on Marco Sau’s curler towards the near bottom corner after four minutes.
The Elefantini also threatened, but Francesco Lodi is more accustomed to using his feet and it showed when his free header was over from seven yards on a Gino Peruzzi cross.
Lodi did considerably better with a free kick from the edge of the box, forcing Vlada Avramov into a fingertip save under the bar. Albin Ekdal knocked down a cross for Sau, but it was intercepted at the last moment by some slightly panicked defending in a rainy night in Sicily.
Sau turned very quickly in the box, but his finish was over the bar, while Andujar punched away a dangerous Nene free kick. Cagliari had penalty appeals for a handling offence, but replays show it struck Nicolas Spolli on the chest.
The hosts had a great double opportunity in first half stoppages, as Keko’s shot was charged down and Avramov just about kept out the Pablo Barrientos follow-up at the second attempt.
Lodi ballooned over the bar, but it was Cagliari who took the lead with Matias Vecino’s second goal in as many games. Sau’s attempt was charged down, but the Fiorentina loaner spun round quickly to turn in the rebound from 10 yards.
Catania got back on track, as Lodi curled one of his trademark free kicks towards the far post, where he found a Gonzalo Bergessio glancing header from five yards.
Their tails were up and they were even more motivated after Cagliari went down to 10 men, as Danilo Avelar received a second yellow card for holding Sebastian Leto’s jersey.
Davide Astori charged down a Leto snapshot, but Cristian Biraghi went incredibly close when his screamer flew across Avramov only to bounce off the inside of the far post.
It was put out of play and from the resulting Lodi corner Nicolas Spolli’s towering header thumped the crossbar, so Catania rattled the woodwork twice in 40 seconds.
Another Lodi free kick was into the defensive wall and in stoppages Peruzzi nodded over, as the Sardinians held on for a precious point.
