Knoxville will open up the Class three-A girls postseason against South Tama on Wednesday night. Coach Jim Utimarkt says South Tama is a good team that has a lot of size that will be tough to deal with. Another thing that worries Utimarkt is the familiarity between the two teams. After playing each other during the regular seasonthere is not a lot either team can be surprised about. Knoxville will play South Tama Wednesday night at seven.
