Adam Johnson's wonder-goal and late strikes from Samir Nasri and Stefan Savic wrapped up City's second half master-class leading furious Rovers fans to chant for the dismissal of boss Steve Kean.
Despite accepting Edin Dzeko's apology for his outburst at being substituted in midweek, Mancini had dropped the Bosnian to the bench and opted to give Balotelli his chance.
It was an inspired decision with Balotelli looking by far the liveliest of City's attacking options, particularly when Sergio Aguero limped off injured on the half-hour.
Rovers had started solidly enough butit quickly became apparent they would have to guard against City's speed and sharpness, with Chris Samba cutting out a dangerous Vincent Kompany cross.

The visitors had their first real chance in the 10th minute when David Silva cut into the box from the left and his cross was parried by Paul Robinson into the path of Balotelli, who blazed over.
Rovers responded two minutes later with a swinging cross from Morten Gamst Pedersen on the left, which was aimed for the head of Samba before being cut out by Joleon Lescott.

Flying high: Johnson opened the scoring in the second half
For all their neat possession, Mancini's men were struggling to unduly threaten the Rovers defence, with Silva guilty of spooning a 25th minute half-chance high over the bar. City's striking options, already diminished by the suspension of Tevez, were further hit when Aguero limped off with an apparent groin strain.
Nasri came on to replace Aguero, and his first act was to screw a low shot towards the Rovers goal which was deflected out for a corner by David Goodwillie.

City's inability to find the cutting final ball surfaced again in the 35th minute when a fine move involving Milner and Nasri petered out when Samba beat Balotelli to a clearance inthe box.
Balotelli stepped up his game towardsthe end of the first half, flashing a curling 37th minute effort wide then zipping in front of Samba to shoot into the side-netting.
City looked sharper at the start of the second half, with Silva shooting across the face of goal moments after the restart, then Balotelli driving a right-foot shot against the post.
