However, the rest of the game went the way of the Swedes, who scored six goals in a row to complete a dominant 6-1 victory.
Mysak added two shots on net and over 19 minutes of time on ice to his goal, and was named the play of the game for the Czechs.
United States 11 - Austria 0
Later in the evening, the United States played their second game in as many nights, this time taking on Austria.
Unlike the previous night, Cole Caufield did not manage to find the scoresheet, despite six shot attempts, one of which hit the post.
The alternate captain maintained a +1 rating and was given 17:39 of ice time by his coach Nate Leaman.
