Trinec U20 took this one 6-3 in regulation, and the middle period is the whole story. A 1-1 game after twenty minutes turned into a 4-1 lead by the second intermission, and Liberec never got back inside two.
The opening period was even on the scoreboard, 1-1, with neither side able to separate. Then Trinec put up three unanswered in the second — the turning point, plainly — and closed at 4-1. Liberec matched Trinec's two goals in the third, but chasing three with twenty minutes left is a different game.
The number that matters: 3-0 in the second period. Without scorers and assists on the sheet, that swing is the cleanest read on the night — Trinec won the game in the twenty minutes that Liberec didn't show up for.
