Breck's run of dominance is finally over.
Orono ended the Mustangs' five-year reign over Class 1A, Section 2 on Thursday at Parade Ice Garden.
The No. 2-seeded Spartans upset top-seeded Breck 2-1 to advance to their first state tournament since 2007.
They also ended the Mustangs' 10-game winning streak, which included 10-1 and 5-2 victories earlier in the section tournament.
Led by goalie Jonathon Flakne and a raucous crowd, Orono (19-8-1) got better as the game progressed.
Breck (22-6-1) controlled the puck throughout the game, but after it scored an early power-play goal, Flakne shut the door.
"Our goaltender was outstanding — poised at the end of the game, when not all of us were," Orono coach Kasey Yoder said.
The Spartans turned a 1-0 deficit into a 2-1 lead after goals by sophomore Jared Gheradi and senior Jake Flemmer. During the scoreless third period, their defense and Flakne made key plays to frustrate the Mustangs' attack.
