It looked like St Louis would take it home. With 3–1 and two minutes of playing time left, it seemed unlikely that Winnipeg would catch up, but that's exactly what happened.
First, Vladislav Namestnikov reduced with two minutes to spare. Then, with two seconds of regular playing time left, came the equalizer.
Kyle Connor sent, after a nice pass from teammate Nikolaj Ehlers, a shot towards the goal that Cole Perfetti could knock in to the home crowd's enormous jubilation.
Then it became, at the very least, an overtime thriller, where Winnipeg first 16 minutes into the second overtime period scored the decisive goal. The 4–3 win means that Winnipeg will move on to the quarterfinals, where they will face Dallas.
