Holloway burned past Elias Pettersson and Quinn Hughes to score a beautiful opening goal in the first period, notching the first of five at even strength for Edmonton in Game 6 before Zach Hyman restored their lead a period later, erasing Nils Hoglander's tying goal that arrived two minutes after the Oilers went ahead in the opening frame.
"I think we just played fast," Hyman said. "I think when we're playing fast, we're getting more opportunities and more looks at their net and I thought we got some good looks off the cycle, too. We've gotten looks all series, but I think we bore down on our chances and made good on them."
Following Hyman's league-leading 10th goal of the postseason, Edmonton scored four unanswered goals and limited Vancouver to only 11 shots over the final two periods, with Stuart Skinner bouncing back in his return to the Oilers' crease with 14 saves to claim the victory.
The Oilers were led offensively by their top players all evening, with Evander Kane wrapping up the scoring with his fourth goal of the playoffs on a quick shot that came from a clean face-off win by Leon Draisaitl with less than seven minutes left in the third period.
Game 7 will be at Rogers Arena in Vancouver on Monday, with puck drop slated for 7:00 pm MT.
"This group has been through lots of adversity throughout the season, and even though we have a lot of skill, we're hard workers," defenceman Vincent Desharnais said. "If we can match their compete level, I think Game 7 will be a good one for us."
