Washington outshot Utah 15-7 in the third.
“I think even when we got down 2-0, I feel like we knew we were going to come back and score,” Strome said. “Got a couple of power plays and got back in. Not a great second, [but we] battled hard in the third to get back in and grab a point.”
Vejmelka forced the shootout when he stretched out his left pad to deny Jakob Chychrun on a one-timer from point-blank range with 10 seconds left in overtime.
“We knew they were going to have a push back, but we stuck with it,” Schmaltz said. “[Vejmelka] made some great saves for us. Two points against one of the top teams in the League, we’ll take it.”
