Atlanta has won 27 of its last 29 games and is one victory shy of tying the longest winning streak in franchise history set in 1993.
Al Horford, named Eastern Conference Player of the Week on Monday, accounted for 14 points, seven assists and six rebounds in the win.
The first quarter was a forgetful one for both teams. Detroit did not seem to enjoy the early start time, missing its first seven shots from the floor. Atlanta slowly built an 8-0 lead over the opening minutes before Drummond's dunk gave the Pistons their first points 4:34 into the game.
The Hawks shot just 31.8 percent (7-of-22) from the floor over the first 12 minutes, limited Detroit to 24 percent (6-of-25) shooting and took a 16-12 lead into the second.
Both offenses ramped up the production a little in the second, with Atlanta grabbing a 44-41 lead at the break.
Anthony Tolliver's 3-pointer cut the Pistons deficit to 60-59, but the Hawks ended the final 1:39 of the third on an 8-2 run.
Scott scored eight straight points for Atlanta early in the fourth, then Kent Bazemore buried a corner 3 moments later to give the Hawks an 83-74 lead. Monroe followed with a pair of free throws, but seven points was the closest Detroit got down the stretch.
