The Panthers' Mason Arens led all scorers with 19 points. Point guard Dylan Debilzen also reached double figures netting 10 points.
No one for the Arrows scored in double figures. Easton Nelson led the way with 7 and Brodie Ecker added 6. The cold-shooting Arrows shot just 23% (9/40) from the field.
"Parkers shot the ball better than we did and forced us to take closely contested shots," said Ashby Head Coach John Holsten. "Every possession for us tonight was a grind."
The Arrows have their overall record fall to 5-14. They host the Verndale Pirates Thursday night.
