BK Mlada Boleslav U20 handled Dukla Jihlava U20 4-1 in regulation, and the middle period settled it. A two-goal second stretched a one-goal lead to 3-0 and left Jihlava chasing the rest of the night.
Boleslav opened the scoring in the 14th minute and carried a 1-0 lead to the first intermission. Goals in the 31st and 34th minutes made it 3-0 after 40, and a fourth in the 42nd killed whatever push the visitors had left; Jihlava finally broke through in the 54th.
The number that frames it: four goals across three periods, with three of them inside a 28-minute window from the 14th to the 42nd. Jihlava's lone tally came with the game already decided, and Boleslav's shutout bid held until the 54th minute.
