A game of few opportunities saw Bologna score a late winner to take all three points away at Genoa.
The 38th minute of the first half saw the opening period's best chance as Bologna keeper Antonio Mirante kept out a close-range header from Sebastien de Maio.
Goran Pandev also came close to breaking the deadlock in the first half as he tested Mirante on several occasions.
However, the keeper was equal to the Macedonia man's efforts as the teams went into half time at 0-0.
The turning point of the second half was the sending off of Diego Perotti in the 80th minute.
Bologna made their numerical advantage count in stoppage time as Luca Rossettini headed home from Franco Brienza's cross to hand Roberto Donadoni's men all three points.
Reported Chelsea and Manchester City target Amadou Diawara was given his marching orders in the dying seconds of the game for a second bookable offence.
The victory moves Bologna up to 13th in the Serie A table, while Genoa are now in 16th.
