Brendan Perlini scored three goals against his former team, and Chicago ripped the Arizona Coyotes 7-1 on Monday night for its third straight win.
Patrick Kane fired in his 41st goal as Chicago moved within five points of the second wild card in the Western Conference. Jonathan Toews, Brandon Saad and Chris Kunitz also scored, and Corey Crawford made 24 saves.
Perlini has six goals in his last five games and 11 for the season. He has clicked on a line with Dylan Strome, who joined him in a trade from Arizona on Nov. 25, 2018, for center Nick Schmaltz.
Perlini missed on a couple more prime chances before barely tapping in a sliding puck for his third goal with 3.6 seconds left.
Arizona had won eight of nine to surge back into the playoff picture. Richard Panik scored against his former team early in the first period, but the Blackhawks took charge midway through the opening frame.
Toews converted a penalty shot in the second period to reach 30 goals for the first time since the 2010-11 season and third time overall.
Arizona's Darcy Kuemper made his 10th straight start, but was replaced by Calvin Pickard after giving up four goals on 16 shots. Pickard blocked 15 of 18 shots.
The Blackhawks are at Toronto on Wednesday night.
