Hintz got the Stars to within 3-1 at 15:37, scoring in the low slot with a tip of Heiskanen’s shot from the top of the left circle.
Dallas outshot Chicago 23-5 in the second.
“We're in the learning process,” Mrazek said. “I think we're learning how to close those games and how to play against teams like Dallas, [a] top two or three team in the NHL, and we have to just learn mentally and physically how to play those games and have a game plan and finish those games when we can.”
Benn cut it to 3-2 at 15:37 of the third period with his 20th goal of the season, tipping a Heiskanen shot. The goal was upheld upon video review by the NHL Situation Room.
“When you’re on an eight-game winning streak, you hope that puck luck can continue a little bit,” Stars coach Pete DeBoer. “We had some during the streak and tonight we didn’t have enough of it. Credit to them, they played hard, they blocked 25, 30 shots (27). Mrazek was good. You go into any building if the opponent’s goalie is First Star and their team is blocking 20-30 shots, you’re going to be in for a tight game. So credit to them.”
NOTES: Stars forward Mavrik Bourque made his NHL debut after being called up from Texas of the American Hockey League on Friday. The 22-year-old had two shots on goal and was 2-for-6 on face-offs in 10:19 of ice time. “It felt good,” Bourque said. “Been waiting for that for a while and to get the first one was pretty awesome. Unfortunately you always want to win in your first game, but that’s part of it.” He was leading the AHL with 72 points (26 goals, 46 assists) in 66 games. … Bourque replaced Tyler Seguin, who is managing an upper-body injury that caused him to miss 11 games from Feb. 24-March 16. Seguin is expected to play Sunday. … Bedard scored his seventh game-opening goal in the NHL, passing Denis Savard and Murray Balfour for the most by a rookie in Blackhawks history. Bedard’s 22 goals are the third-most by an 18-year-old in the past 10 years, behind Columbus Blue Jackets forward Patrik Laine (36) and Colorado Avalanche center Nathan MacKinnon (24).
