Tyler Seguin scored the tiebreaking goal in the second period and the Dallas Stars beat the Chicago Blackhawks 2-1 on Sunday.
The Stars' Joe Pavelski opened the scoring in the first period.
Blackhawks rookie Dominik Kubalik tied the game in the second period on the power play.
Seguin's goal came at 16:29 of the second. He outmaneuvered Chicago goalie Corey Crawford, whose 31 saves included stopping a second-period penalty shot by Mattias Janmark.
Dallas goalie Anton Khudobin also stopped 31 shots. As the backup to Ben Bishop, Khudobin has a 15-7-2 record, including 4-0-1 in his last five games.
Khudobin's saves included a shot by the Blackhawks' Jonathan Toews from the right faceoff circle with an extra Chicago skater on the ice in the final minute.
The Stars remained third in the Central Division. They were coming off a 5-1 loss to division leader St. Louis on Friday.
Kubalik scored at the end of a 4-on-3 power play, taking a pass from Patrick Kane and firing a slap shot from the right faceoff dot past Khudobin at 7:06 of the second period. An interference penalty against the Stars' Radek Faksa ended just as Kubalik took his shot.
Chicago (2-6-2 in its last 10 games) was 1 for 5 with a man advantage. The Blackhawks had a power-play goal in each of their last two games after going 0 for 17 in their previous six.
The 1-1 tie lasted until 16:29 of the second, when Seguin took a pass across the slot from Corey Perry. Seguin waited as Crawford slid across the goal mouth to confront him, and the Dallas center then put a wrist shot past him to a vacant spot in the right of the net.
Just 31 seconds later, the Stars' Mattias Janmark earned a penalty shot when Chicago's Duncan Keith hooked him on a breakaway. The shot went off Crawford's blocker and over the net.
The Blackhawks play the second in a four-game trip on Tuesday at St. Louis.
