Vegas allowed two power-play goals on Pittsburgh’s four chances after giving up one on 12 opportunities the previous four games.
“I think we just had poor execution all game long,” Golden Knights forward Reilly Smith said. “Obviously, our penalty kill has been pretty good for us and that wasn’t good enough tonight.”
Rickard Rakell pushed it to 4-0 on another power play at 15:06, stopping a shot from Karlsson with his left skate and wrapping a shot around Hill.
Brazeau scored on a wrist shot from above the right circle at 14:59 of the third period for the 5-0 final.
“Second period, they took it to us,” McNabb said. “We were out of it, basically.”
