The Bruins spent much of their first trip to Utah living dangerously and got away with it for most of the night.

But their luck ran out in overtime when Michael Kesselring ripped a shot past Jeremy Swayman to give the Utah Hockey Club a 2-1 win over Boston at the Delta Center in the teams’ first meeting since the Coyotes moved from Arizona.

Naturally, a fourth-liner for the Bruins (3-2-1) scored their only goal of the game. But Cole Koepke didn’t skate with his regular linemates as he gave the Bruins a 1-0 lead.

It was Brad Marchand who set it up with 7:11 left in the second period for Koepke’s third goal of the season.

Jeremy Swayman, some luck and a smart challenge kept that lead alive deep into the third.

Kailer Yamamoto appeared to have tied the game with 13:12 remaining, but the Bruins’ video staff quickly determined Utah was offside and Jim Montgomery’s challenge canceled out the goal.

Vladislav Kolyachonok’s equalizer could not be reversed with 5:09 left in the third period, which forced overtime.

David Pastrnak was whistled for a tripping penalty 42 seconds into the 3-on-3 session, immediately putting the Bruins on their heels. Boston converted the penalty, but four seconds after Pastrnak’s release, Kesselring scored the winner.

Jeremy Swayman made 31 saves.

The Bruins are in Nashville on Tuesday.
