The Broncs lost a heartbreaker to host Granite 6-5.
Blair battled back through the losers bracket Friday and defeated both Cheyenne and Ganite to force Saturday’s if necessary game.
Blair led 3-1 going into the sixth before the Panthers rallied for four runs to take a 5-3 margin.
However Blair rallied in the seventh inning thanks to sophomore catcher Matt Martin who blasted a two-run homer over the centerfield fence.
But Granite pushed across the winning run in the bottom of the seventh.
