Senior Katie Jo Myers started the inning off with a double, Kaila Wilkinson drove Myers in, followed by a Hayley Beckstrom single who then scored on a Shelby Carter double to left field.
Lisa Maulden smacked a triple into center field then Sammii Jimenez drove her in.
Jordan Walley followed that up with a walk and set up Kiley Dunn to pick up a pair of RBIs with a long single up the middle.
