Caleb Brannon hit two 3-pointers in an 8-2 run to start the fourth quarter that put the game out of reach.
Danville got no closer than eight in the final four minutes.
Avery Motes led the Warriors with 16 points, 15 coming in the fourth quarter. Ian Asher also finished in double figures with 13 points, but shot 3-of-16 from the field.
While the two teams are no longer in the same sectional, Barber said the sectional-like atmosphere will help his team, now 5-1.
“These kinds of games make you better,” Barber said. “Hopefully when the realignment comes we can get back in it with our Sagamore Conference rivals. It makes for a better sectional for everyone. I wish Lebanon the best, we won’t see them in the sectional but they have a great shot at it this year.”
