Milan: Jasmin Kurtic hit a first-half brace and Alejandro Gomez added a late third as Atalanta's Serie A purple patch continued with a 3-0 home win over Genoa on Sunday.
The Bergamo-based side had already accounted for Napoli and Inter Milan at home, and a series of encouraging away results mean Gian Piero Gasperini's men move up to provisional fifth place at eight points behind leaders Juventus.
Juventus moved seven points clear of principal title rivals Napoli with a 2-1 win over them in Turin on Saturday, where former Napoli striker Gonzalo Higuain hit a 71st minute winner for the champions.
Roma, in second at five points adrift, can close the gap to two points and underline their own title credentials with a win at Empoli later Sunday.
A home win for AC Milan over Pescara would move Vincenzo Montella's men up to third at five points behind Juve, while city rivals Inter Milan, already trailing by 13 points, face a tough trip to Sampdoria in Sunday's late game.
