The Delfini scored two own goals as the hosts added to their impressive recent run of form with an ultimately facile victory that sees them close to within seven points of second
The home side scored with the first attack of the game, after Antonio Nocerino was given a chance that he simply could not miss less than a minute into the game. The Rossoneri then doubled their lead when Robinho’s corner was clumsily headed into his own net by Elvis Abbruscato.
Christian Terlizzi pulled a goal back for the away side with a superb header on 56 minutes and Antonio Balzano nearly scored an equaliser a few minutes later. However, Massimiliano Allegri's men finished the game off with two late strikes: an own goal from Jonathas and another tap-in, this time from Stephan El Shaarawy.
The in-form Rossoneri made it clear that they were in a confident and ambitious frame of mind right from the off, though they were aided by Pescara's doziness. El Shaarawy was left totally unmarked as he made a clever run into the box and once he picked up the ball, he had plenty of promising options, ultimately electing to the slide the ball across the area to the waiting Nocerino, who applied a simple finish at the back post.
The home team maintained their pressure in the opening stages and, after El Shaarawy had swung a cross into the box for Pazzini, Delfini defender Antonio Balzano nearly headed the ball into his goal. Luckily for him, though, Mattia Perin was on his toes to save.
Milan thought that they had netted a second when Giampaolo Pazzini smashed home Robinho's free kick, but the referee saw an infringement and made the hosts retake the set piece.
The Rossoneri created a number of half-chances as the game progressed but could not add to their lead before half-time.
Pescara made a lively start to the second half despite taking off Vladimir Weiss, who had been their main threat. Francesco Modesto’s delivery from wide met the head of Birkir Bjarnason but he could not get enough power on his shot to worry Marco Amelia.
The away side then shot themselves in the foot as Abruscatto headed Robinho's corner into his own net. The Pescara striker was clearly trying to put it back out for another corner but his header was wild and gave Perin little chance to save it.
The visitors gave themselves a route back into the game after Riccardo Montolivo let Terlizzi have too much space when defending a set piece, and the defender headed home to make it 2-1.
All of a sudden things looked a lot brighter for Pescara, as Balzano’s 25-yard drive crashed against the post, denying them an equaliser.
However, Milan simply redoubled their efforts and Jonathas scored the second own goal of the match to make Pescara's task all the harder before El Shaarawy put the outcome beyond all doubt by making it 4-1 on 81 minutes after slotting home Pazzini's ball across the six-yard box.
The victory means Milan remain seventh, but they are now just seven points behind second-placed Inter.
