The facility is primarily used by the Southwestern College Moundbuilders football and track & field teams.

The grass field is named "Art Kahler Field" from prominent Southwestern alum Art Kahler and the surrounding track is named "Monypenny Track" in honor of alum William Monypenny.

In January 2009, the school announced plans for a major renovation, including changing the name from "Sonner Stadium" to "Richard L. Jantz Stadium".

The renovations are expected to attract better student-athletes and bigger events to Winfield.
