The Stars beat Chicago 5-4 in overtime in Dallas on Friday night.
The Stars took a 1-0 lead at 11:35 of the first period when Craig Smith deflected Steel's long wrist shot from the right point past Mrazek.
Ryan Suter made it 2-0 at 17:16 when his wrist shot from the high slot on the rush deflected in off a Chicago defender.
Seguin made it 3-0 when he knocked a back-door pass from Marchment into a wide-open net at 19:11 for his 11th goal of the season.
Dallas outshot Chicago 17-6 in dominating the opening period and the three goals matched the Stars' season high.
Chicago's best early chance came when Connor Bedard's shot deflected off Wedgewood's blocker and then the crossbar.
Steel made it 4-0 at 3:43 of the second period. He worked a give-and-go with Jason Robertson at center ice and lifted a backhander over Mrazek from the right circle.
Marchment increased the lead to 5-0 with a power-play goal at 12:50, receiving a pass from Seguin and scoring from between the circles for his 11th of the season.
Kurashev got the Blackhawks on the board 39 seconds into third period when he completed a pretty passing sequence by scoring on a one-timer from the right circle off a cross-ice pass from Bedard on a power play.
Hintz made it 6-1 when he tipped in the rebound of Thomas Harley's shot at 4:46.
Marchment scored his second goal of the game when he redirected Seguin's shot home at 14:29 and then added a tip-in at 18:46 for the 8-1 final.
