Alliance used a 19-2 run just leading into half to take complete control of the game and run past Chadron 71-44.
The first ten and a half minutes were a back and forth affair with Chadron actually holding a 19-14 lead in the 2nd quarter before Alliance went on their run.
An 8-0 spurt to start the 3rd quarter put the Bulldogs up by 20 and Alliance cruised the rest of the way.
Justus Alcorn carried Chadron with 17 points.
The Cardinals are now 9-8 on the season and will host Rapid City Christian on Friday.
