A few moments later, it was announced that his first-period goal was being changed to Mikael Granlund, who got a late stick on the puck just before it crossed the goal line.
Imagine the confusion for the 19,261 -- the largest crowd of the season -- when Staal scored again on a breakaway 7:46 into the third period.
Hats rained down from all levels of the area, littering the ice below.
There was just one problem.
"That's not a hat trick," Staal said to teammate Jason Zucker, as the two waited on the bench for the ice crew to retrieve the headwear.
Staal knew it. Zucker knew it. Granlund knew it.
But forgive the fans for not taking notice, not with Minnesota scoring a franchise-record-tying eight goals in an 8-3 win against the rival St. Louis Blues. At that particular moment, a scoring change wasn't the first thing on their minds.
"Once the hats started coming, I was like, 'uh oh.' I knew it wasn't a hat trick because Granny told me he touched that one before it went in," Staal said. "I celebrated a good assist on that one. But that's ok. It was one of those nights. It was fun."
