Siena’s hopes of avoiding the drop took another massive blow, as Gonzalo Bergessio’s hat-trick set a new club record for Catania.
The Elefantini wanted to set a new club record for points in a single Serie A season, but had Mariano Andujar, Giovanni Marchese and Giuseppe Bellusci suspended. Siena were more desperate, as two consecutive defeats saw them slide back into penultimate place. Simone Vergassola sat out a ban.
Gianluca Pegolo had to rush off his line to parry from Gonzalo Bergessio after a smart Pablo Barrientos assist sent him clear on goal.
Bergessio got his goal soon after. Leandro Castro trapped a long ball and distracted his defender to then put a sneaky disguised pass to his left where Bergessio ran in with an angled drive.
Matteo Rubin flashed a half-volley past the upright and Alvarez went off with a thigh problem.
Siena’s afternoon went from bad to worse when Dias Felipe was sent off. It was a very harsh decision, as he fell on to the ball with his arm in the D and it was considered to be a clear goal-scoring opportunity.
Catania had the ball in the back of the net straight after the restart, but play had already been stopped for a Castro handling offence.
Alberto Frison had his palms stung by an Alessio Sestu volley at the near post, but moments later Catania doubled their lead.
Bergessio gathered with his back to goal from a deflected Castro assist, spun round and fired in a daisy-cutter from 12 yards.
It was a Bergessio hat-trick when he sprung the offside trap – a contentious decision – to volley in from seven yards with the inside of his left foot.
Sent off: Felipe 43 (S)
