Substitute Andres Romero scored in the 76th minute and Didier Drogba got his fifth goal in four starts to lift the Montreal Impact to a 2-1 victory over the Chicago Fire on Wednesday night.
The Impact (11-11-6) improved to 3-0-2 since Mauro Biello replaced Frank Klopas as head coach.
David Accam scored for the last-place Fire (7-17-6), who lost their fourth in a row despite a coaching change this week that saw Brian Bliss replace Canadian Frank Yallop.
Montreal went down a man for a third straight game after Laurent Ciman was shown his second yellow card of the game in the 90th minute.
He will be suspended for a home game Saturday against D.C. United, as will Romero, who got a yellow card for taking his shirt off after the winning goal.
The Fire did a tidy job of containing Drogba for most of the first half, but in the 39th minute, Nigel Reo-Coker swung wide on the right side and put in a cross. The former Chelsea star looked to throw down defender Jeff Larentowicz as he lunged forward to head it in but there was no call on his fifth goal in as many MLS games.
