On the ensuing power play for delay of game, Robertson put the Stars ahead 2-1 at 1:38 of the second period.
"Kudos to our power play and everyone scoring with a couple of seconds left (in the first period), and then we kind of double-dipped there when they got the coach's challenge (penalty), and that kind of swung the game around," Robertson said.
Riley Tufte gave the Stars a 3-1 lead at 3:13 with his first NHL goal.
"I started falling down when I scored, so I wasn't sure if it went in right away, but I saw it going back in the net and it was an awesome feeling," said Tufte, a native of Blaine, Minnesota. "Coming home and being able to play here and getting the first one here tops it off."
Robertson scored through a screen to extend the lead 4-1 at 9:52.
"It seems like one little thing starts a little bit of a snowball effect in a game like that," said Kahkonen, who was pulled after the goal. "It's not the way it should be, but we just really have to dig ourselves out of this."
Kaprizov cut it to 4-2 at 16:19 of the third period, beating Oettinger low stick side with Talbot on the bench for the extra skater, before making it 4-3 at 18:03 with another 6-on-5 goal.
