Brandon Saad scored his first two goals of the post-season, and Chicago earned its sixth consecutive win despite stretches of lacklustre play in the second and third periods. Corey Crawford made 18 saves in another solid performance.
Cody McCormick scored his second career playoff goal, but Minnesota missed another chance to steal home-ice advantage from the defending Stanley Cup champions.
The series opener was tied at 2 in the third period before Patrick Kane scored two of Chicago's final three goals in a 5-2 victory on Friday night.
It was a different game in the past, that's for sure. It's not exactly what I was expecting but I think the experience paid off for a lot of our guys that realized what it takes in a Game 7. Realistically the effort we put forward, we might not even had to put 60 [minutes], but we just couldn't get a couple bounces to go our way and we just kept pushing.
