Winning pitcher Becky Lemke (4-0) struck out 10. The four runs by Nebraska are the only runs scored against UA this year.
The Wildcats (8-0) pounded five home runs for the second consecutive game. Earlier UA clouted five against Louisiana State. Third baseman Toni Mascarenas hit one in the morning and two against the Huskers to give her a team-high six.
