Relegation is now a very real possibility for defeated Siena.
Catania romped to victory over Siena in this Serie A match, winning 3-0.
The Elefanti dominated the game from start to finish and sealed all three points through a hat-trick from Gonzalo Bergessio.
Bergessio got the better of Siena goalkeeper Gianluca Pegolo in the first half after a good pass from Lucas Castro, before scoring his second shortly after half-time and completing a great day with his third goal late on.
The away side had Felipe sent off with a straight red after handling the ball on the edge of the penalty area and now look perilously close to getting relegated with just three matches left.
