Unbeaten Juventus remained three points clear of AC Milan in the Serie A title race after both scraped 1-0 wins against Genoa and Cesena on Wednesday.
Former Milan striker Marco Borriello scored his first goal for Juventus 11 minutes from time and looked to have extended the club's advantage in the title race, as the Rossoneri were still drawing 0-0 at home.
But Kevin-Prince Boateng kept Milan very much in the race with the winner five minutes from time.
Andrea Pirlo missed his second penalty in a row for Juventus in the eighth minute.
The 33rd round of fixtures was postponed following the death of Piermario Morosini on April 14. Morosini -- on loan from Udinese -- collapsed and died after suffering cardiac arrest during Livorno's match at Pescara in Serie B.
