Knoxville went three-and-oh at the Centerville Softball Invitational yesterday. The Panthers won all three games by convincing scores as they blasted Moravia 13-4 in the first game, beat up Moulton-Udell in the second game 10-1, and smashed Davis County 11-1 in six innings in the third and final contest. Kylie Bishop brought her big bat to Centerville as she went 8/11 on the day with a home run and four doubles. Knoxville is now 3-3 on the season and will host South Tama on Tuesday.
