The Rossoneri had the better of the opening exchanges and it was left to the influential midfielder to break the deadlock eight minutes before half-time.
Angelo Peruzzi was forced to make a save from Andrei Shevchenko and pushed it out to Filippo Inzaghi who aimed his effort at goal only for Fernando Couto to block with his hand.
While the Italian international turned away from play to appeal for a penalty, Pirlo calmly slotted home to give Milan a 1-0 lead that proved to be enough for all three points.
Roma closed the gap at the top with a 2-0 win over Parma at Stadio Olimpico.
The Giallorossi secured all the points and in so doing, ended Parma's unbeaten record.
Argentine defender Walter Samuel put Fabio Capello's side on their way after 28 minutes, before Italian starlet Antonio Cassano (pictured) sealed victory on the hour.
Chievo missed the chance to move sixth after they were held to a 1-1 draw at home to Sampdoria.
Carvalho Amauri put Chievo ahead on 24 minutes, but Aimo Diana's goal on the hour made sure Samp took a share of the spoils.
Modena, however, did not fail to take advantage and their 2-0 win over Lecce means they find themselves in sixth.
Fabio Vignaroli (63) and the highly-rated Diomansy Kamara (90) sealed victory over Lecce - who had ten men for most of the second period after Klas Ingesson saw red.
Udinese are also significant movers in the top half of the table as they moved into seventh with a 2-0 success at home to Empoli.
Goals in the first half from Argentine veteran Nestor Sensini (31) and Vincenzo Iaquinta (35) was enough for the home side to grab the three points.
Perugia let a two goal lead slip at The Renato Della Ara as Bologna came from behind to seal a 2-2 draw.
A Fausto Rossini own goal put Perugia ahead after 47 minutes and then a Jay Bothroyd strike with 15 minutes left looked to have sealed the win.
However, two goals in two minutes from Sam Dalla Bona (76) and villain turned hero Rossini (78) meant the game ended all square.
Reggina jumped to tenth after a 2-1 win over Siena at The Stadio Oreste Granillo.
Mozart set the home side on their way after 21 minutes, before two goals in the final minute decided the game.
Julio Leon pounced to make it 2-0, but Tore Andre Flo scored to make a frantic finale to the game.
Siena could not pull level, but they did have midfielder Giovanni Guigou dismissed.
