Dallas forward Mikko Rantanen, who leads the team with 63 points (19 goals, 44 assists), did not play because of an illness.
Morgan Geekie and Fraser Minten scored for the Bruins (28-20-2), who had outscored their opponents 27-7 in the previous six games. Jeremy Swayman allowed six goals on 34 shots before being pulled at 6:37 of the third period; Joonas Korpisalo made three saves in relief.
Wyatt Johnston put the Stars ahead 1-0 at 16:08 of the first period with his 26th goal this season and League-leading 16th on the power play. Hintz moved a pass from Heiskanen to Johnston low in the left face-off circle for a one-timer.
Bourque made it 2-0 on another power play at 19:47. After having an initial attempt denied by a diving save from Swayman, he scored on the rebound with a snap shot at the left post.
Esa Lindell extended the lead to 3-0 at 8:26 of the second period on a one-timer from the point.
Hryckowian pushed it to 4-0 at 19:29, getting credit when a rebound off the inside of Swayman’s left pad went off his skate and in. The goal was initially waved off due to a kicking motion, but video review determined the puck hit the stick of Bruins forward Mark Kastelic before entering the Boston net.
Robertson scored on a wraparound to make it 5-0 at 3:15 of the third period, and roofed a snap shot to extend it to 6-0 at 6:37 on his 29th goal.
