1-0, min. 53, Antonelli.
Milan and Chievo Verona met at the San Siro on Wednesday night, with the sides sat in 10th and 11th place respectively.
Under Sinisa Mihajlovic, the Rossoneri had undergone a fluctuating start in which the team had struggled to find any real consistency.
Rolando Maran's Chievo outfit had made a great start to the season, sitting high in the standing after a few games played, however in the matches preceding this they had picked up just 4 points from 15.
Andrea Bertolacci started for Milan at a rain-soaked San Siro, as well as young 'keeper Gigi Donnarumma as Mihajlovic looked to follow up Sunday's win over Sassuolo with another success to ease his position.
Chievo had the first attempt of the game as Valter Birsa curled a free kick into the box from the left side that was flicked towards goal by Lucas Castro. Donnarumma saved easily.
Juraj Kucka had a deflected shot saved easily in the 4th minute as both teams looked to seize the early initiative.
Ignazio Abate was forced off in the 14th minute due to injury, replaced by Mattia De Sciglio.
In amongst the rain there were a lot of slippery challenges and knocks, but Andrea Bertolacci came close to breaking the deadlock in the 22nd minute as a Cerci cross from the right connected with him, but the midfielder headed narrowly over.
Milan struggled to find the intensity needed to break down a resolute Chievo backline; the game largely played at walking pace with several unsuccessful probes.
Alessio Cerci temporarily got in behind Chievo in the 33rd minute, however he curled his effort wide as it was heading towards the top left corner.
Bonaventura had a half chance in minute 39 when Alex clipped a ball in towards the far post, though the Italian never made proper contact.
Cerci headed over and wide at the near post with three minutes remaining in the first half as De Sciglio for once was on the money with his cross.
Chievo had a chance moments before the break; Sergio Pellissier flicked a header from Birsa's cross goalwards, with Donnarumma forced to palm over the bar.
Milan had a spell of four corners in front of the Curva Sud to end the half, ending when Bonaventura struck wide from the edge of the area.
The teams went in deadlocked at the break; neither side doing enough to take the lead in a timid affair.
The hosts undoubtedly had the better of the spoils but Chievo had the better of the chances, and but for Donnarumma could easily have led.
Nicolas Frey made way for Fabrizio Cacciatore to start the second half.
Bizzarri made a wonderful save as Alex met a Bonaventura free kick in the 51st minute, the 37-year-old Argentinian sprawling to stay equal with the effort.
Milan made the early pressure pay as Luca Antonelli opened the scoring eight minutes into the second period.
Antonelli gives Milan the lead
A sustained spell of pressure from the Rossoneri ended with Carlos Bacca laying off for the full-back inside the area; Antonelli curling an effort just inside the far right post past a motionless Bizzarri.
Bonaventura found space on the edge of the area just before the hour, spinning after a Bertolacci dummy, however his effort was weak and easily saved.
Juraj Kucka had an effort from just outside the box deflected wide a couple of minutes later to thwart a dangerous break from the Devils.
Chievo removed a major attacking threat in the 64th minute when Valter Birsa made way for Paul-Jose M'Poku.
Kucka had another chance from almost an identical position as his previous; striking narrowly wide of the left post after a clever feed from Bonaventura.
Paloschi was forced to bite the ball in frustration as he had an effort saved by Donnarumma as he was put through on goal, however the narrow angle meant the 16-year-old stopper always had the advantage.
Moments later Castro almost met a cross as the Flying Donkeys began to search for a leveller.
Bizzarri was called into action in minute 71 when Giacomo Bonaventura fizzed a delivery across the six yard box looking for Cerci. The 'keeper may have got a touch on it to divert it away.
Bonaventura had an opportunity to test the 'keeper just inside the last quarter of an hour, but he struck over from the edge of the box with a first time shot.
Milan were having a lot of chances to kill the game but seemingly all were outside the box. Kucka missed another chance in the 82nd minute with a shot wide.
It should have been wrapped up in the same minute when Bertolacci found space just a few yards out on the left, yet somehow the ball stayed out as his driven cross evaded Bacca by inches.
Pinzi was lucky to get away without a second yellow card inside the last five minutes as he chopped down Montolivo inside Rossoneri territory.
Kucka should have definitely sealed the deal in the 89th minute when he met a corner at the far post. Somehow he headed wide from a couple of yards out.
Pinzi disallowed goal
Giampiero Pinzi had a late goal chalked off as he was adjudged to have made contact with Donnarumma in the air before turning the ball in. Maran will not have been happy with that call, although replays showed there was contact.
The whistle blew and Milan had a second straight win thanks to Antonelli's effort early in the second half.
Not a classic performance from the Rossoneri by any means, though they did well to negotiate a tricky opponent in Chievo and deserved maximum points.
The perfect tonic ahead of a tough trip to the capital to face Pioli's Lazio on Sunday evening, while Chievo return home to face Sampdoria on Monday night.
