Pastrnak had two assists, and Jeremy Swayman made 20 saves for the Bruins (20-14-0), who have won five of six and were beginning a five-game homestand.
Barrett Hayton scored, and Vitek Vanecek made 19 saves for Utah (16-16-3), who had won two in a row and will conclude a three-game road trip at the Detroit Red Wings on Wednesday.
“I want more ownership. I don’t know if it’s accountability or ownership,” Utah coach Andre Tourigny said. “We’re in their building. It’s one thing to say it in the room, it’s another thing to buckle up, push back and be ready for their answer. ... Let it hurt and then be professional, mature, assess what we could’ve done better, fix it and get at it tomorrow.”
Hayton scored a power-play goal to give the Mammoth a 1-0 lead at 8:34 of the first period. Sean Durzi sent a sharp pass down to Hayton, who redirected it under the arm of Swayman as the goalie was moving across to cover the left post.
“We had some good movement in Pittsburgh (on Sunday) and found some rotations being interchangeable, always having a guy at the net with an attack mindset, and I thought we did a really good job on that first power play,” Hayton said. “We had a power play at the start of the third period but we didn’t execute. Those are the moments we want to be in and want to come up big for this group, so it’s frustrating not getting it done.”
The Bruins answered with their own power-play goal to tie it 1-1 at 16:01 of the first. Pastrnak sent a cross-ice pass to Geekie in the bottom of the left circle, where he shot into an open net past the diving glove of Vanecek.
“Obviously, I take pride in that a lot, but it’s not something I put a lot of stress on,” Geekie said of his offensive output. “You saw it the other night in St. Louis when (Mark Kastelic and Fraser Minten) had two, and I know Minnesota wasn’t a good outcome (a 6-2 loss on Sunday), but we’re getting goals from everybody. Up and down the lineup we’re built like that and we’re able to rely on different guys, but for me, I just go out there and play hard at both ends of the rink and try to take advantage on special teams.”
