Jack McIntyre scored two power play goals as Black Hawks finished their season series with Detroit, 3-0-1. Black Hawks (4-14-1) are 1-14-0 versus the rest of the league.
With the loss, Red Wings (6-10-3) remain tied in points with New York Rangers for the fourth and final playoff spot, but Rangers have a game in hand. Rangers host Montreal later this week.
If Red Wings and Rangers finish tied in points, Detroit will go to the playoffs based on season series (2-1-1).
But the loss by Red Wings means that Rangers can clinch the playoffs if they manage three points in their final two games---versus Montreal and at Boston.
McIntyre's first goal came with just five seconds remaining in the first period and gave Black Hawks a 2-0 lead.
McIntyre made it 3-0 with his second goal at 3:49 of the second period as Detroit's Red Kelly was serving a five-minute major for spearing.
John Bucyk beat Al Rollins at 9:56 of the second period to draw Detroit to within two goals, but Ken Mosdell answered 1:23 later to restore the three-goal cushion. The goal was Mosdell's first point of the season.
Red Wings managed just 19 shots on goal for the entire game.
Alex Delvecchio scored at 9:10 of the third period but Red Wings could get no closer.
