Pinto gave the Senators a 1-0 lead 51 seconds into the game. After tracking down his own errant pass for Giroux, Pinto scored with a sharp-angled shot from along the goal line that went underneath Schmid’s pad.
Sanderson made it 2-0 with a power-play goal at 13:04, scoring with a one-timer off a pass from Giroux that went in off the post.
“Our first was great, and we dipped a little in the second but stuck with it in the third and was patient to the end,” Sanderson said. “We went into the game trying to have a shot-first mentality in the first couple of seconds on the power play if we have a look. It worked out.”
Brett Howden cut it to 2-1 at 16:52. Mitch Marner took a stretch pass from Shea Theodore at the blue line and dropped the puck for a charging Howden, who sped around Nick Jensen before tucking the puck past the left pad of Ullmark.
“I liked the line [of Howden, Stone and Marner],” Vegas coach Bruce Cassidy said. “'Stoney’s' really good at drawing people to him, and 'Howie’ is good through the middle, so they were able to find some weak-side ice to Marner a couple of times. ‘Howie’ obviously got behind, scored a goal in a way he typically does with speed, driving wide, and making a play tight with the goalie.”
