Huberdeau scored on a rebound on the power play to extend the lead to 2-0 at 9:21, and Andersson made it 3-0 at 12:03 when he shot short side over Bobrovsky's left shoulder.
"I think every chance we gave them they capitalized early on," Reinhart said. "It's tough to play catch-up, especially when the energy isn't there. I think you want to come out, especially on a back to back, play simple and get yourself in the game that way. I think we made it too tough on ourselves early on."
Cousins cut the lead to 3-1 at 9:54 of the second period when he deflected Gustav Forsling's wrist shot from the point by Vladar's pad.
Brett Ritchie made it 4-1 at 15:29, banking a sharp-angled shot off Bobrovsky's left pad, but Reinhart cut it to 4-2 with a wrist shot at 16:55.
"I thought in the second, I thought we had a really good second period and took over most of that and got a lot of momentum back," Tkachuk said. "Then we just opened it up way too much for us in the third. That's not what we want to be known for, opening it up and trading chances. Definitely don't want to be leaving 'Bob' out to dry like we did for most of that third, giving up a lot of partial breakaways or breakaways or odd-man's against."
