The Knoxville Volleyball Squad will play Pella in the class four-A Regional semi-final tomorrow night in Pella. The Panthers got into the semis by defeating Carlisle three sets to one on Monday night in a match that was highlighted by a very noisy Carlisle Gym. Panthers Coach Liz Sanders thinks Pella’s Gym will be just as loud with fans from both sides supporting their teams. She adds the girls will have to communicate differently than normal. Sanders says they have been running a quicker offense to get points in recent days. She adds the girls are getting better at the quicker sets…which makes her hopeful they can stay in the match longer. The winner of tomorrow night’s match will play the winner of the Norwalk and Indianola match Tuesday in Carlisle.
