The Packers got on the board first on a Riccardo Lapertosa shot from 25 yards out, but Cardinal Devante Glover answered 20 minutes later to knot the match at 1-1 where it remained until intermission.
In the second half Glover again found the back of the net with 28 minutes to play with what proved to be the deciding goal.
Orchard View outshot the Packers 11-7. Joe Kortge ended with 9 saves for Fremont and Dakota Palenear made 6 saves for OV. Fremont ended the season 15-4-4 and the Cardinals improve to 15-4-2.
Orchard View will take on Ludington on Wednesday in the first round of the regional tournament in Clare.
