In the first period, USA star Logan Cooley made it 1–0.
The Americans' happiness was short-lived, however, as Jan Mysak equalized only a couple of minutes later.
In the second period, the Czech Republic put in a small push, which turned out to be match-deciding, through goals by Petr Hauser and Matyas Sapovaliv.
Kulich decided in an empty box
In the third period, the USA reduced the lead through Carter Mazur, but they did not get any closer than that.
Instead, it was the Czech Republic's Jiri Kulich who put the last puck of the match, 4–2, into an empty basket.
- Absolutely superb team effort by the Czech Republic!
The USA is underperforming and getting cut, says SVT Sports expert Jonas Andersson.
- The Czech Republic is doing so well defensively.
They play by pretty big margins, they are sacrificial and really are a team machine here today.
It is undeniably the biggest scandal in the tournament and the biggest scandal in quite some time in the context of the Junior World Cup.
Thus, the Czech Republic is JVM semi-final ready.
There, the team faces Canada.
In the second semi-final, Finland and Sweden meet.
