A St. Charles North victory against Streamwood or a Geneva loss to Elgin tonight would give North the outright Upstate Eight Conference River Division boys volleyball title.
"We don't have it in the bag, but we are definitely in the driver's seat," North Stars coach Todd Weimer said. "We've got to keep working hard and win one more."
North won the conference title in 2011 before Geneva and St. Charles East shared the championship last season.
The North Stars clinched at least a share of the crown with a 25-15, 25-18 home sweep of Geneva last week.
