Colton Sissons gave the Golden Knights a 1-0 lead at 8:41 of the first period, tapping in a backhand pass from Bowman at the right post after Parker Wotherspoon turned the puck over while chasing a dump-in.
“It started from a good face-off execution,” Bowman said. “We won it back, we had the high flip in mind, and then [Brett Howden] puts pressure on the 'D.' The puck was just sitting there for me, and it was [Sissons] with a nice goal.”
Dorofeyev extended the lead to 2-0 at 5:02 of the second period. He took a pass below the right circle and roofed a wrist shot over Silovs from close range.
Rakell cut it to 2-1 at 8:26. He got his stick inside on Brayden McNabb and redirected in Bryan Rust's backdoor pass at the right post.
Marner answered back to put Vegas ahead 3-1 at 9:20. Penguins forward Connor Dewar sent a backhand pass in the neutral zone right to Marner, who skated in and dropped the puck to Dorofeyev. Marner then quickly received a return pass while skating toward the net and tucked a shot past the outstretched glove of Silovs.
“He made a great play back,” Marner said of Dorofeyev. “I was lucky enough to make a move."
