In 1993, women's soccer competed as a varsity sport for the first time in the history of Indiana University. Dillinger scored 13 goals for the Hoosiers, five of which were game winners and added eight assists on 61 shots. She led the Hoosiers in every offensive category. Only two Hoosiers have tallied three assists in a single game, Dillinger against Detroit on September 8, and Megan Pipkens in a 3–0 win over Oakland on September 30, 2004. On October 31, Dillinger scored twice and Sheryl Mansberger added another goal as the women's soccer team beat UW-Green Bay, 3–1, to cap a nine-game winning streak and finish Indiana's first varsity season with a 12–6–0 record.
