Edina coach Laura Slominski couldn't be sure whether Hopkins forward Becky Kortum made a great play or received a big break.
Kortum appeared to keep the puck onside by the width of a skate lace before scoring Hopkins' first goal of the game in the second period. She did not watch the replay. But Kortum knew what the goal meant to the victory.
"I wanted to get the puck to the net," she said. "The goal gave us momentum the rest of the game."
Kortum, the Star Tribune Metro Player of the Year, got Hopkins on the board after a less-than-productive first period in which the Royals managed just two shots.
Jenna Westerham, Ashley Dieck and Cara Johnson followed with power-play goals to push Hopkins past its Classic Lake Conference rival in their third meeting this season.
Edina outshot Hopkins 28-14 and put 17 pucks on goalie Kallie Billadeau in the third period alone.
