Paolo Maldini sealed a 1-0 victory for Milan over Messina, while Chievo beat Udinese 2-0.
Evergreen defender Maldini headed home Andrea Pirlo's free kick in the 13th minute to secure a much-needed victory for Milan, who had not won any of their last four Serie A games.
The result lifts Milan to 14th place, but they remain a massive 19 points adrift of table-toppers Internazionale.
19-year-old Nigerian striker Victor Obinna was the star of the show for Chievo as they climbed out of the relegation zone with their first win of the season against high-flying Udinese.
Obinna opened the scoring in the 31st minute after visiting keeper Morgan De Sanctis spilled the ball into his path.
He then made it 2-0 from the penalty spot (71) after Brazilian defender Felipe handled.
