The facility is owned and operated by the city's Parks and Recreation department, and holds 10,000 people.

It is the spring training home of the Milwaukee Brewers and their minor league affiliates (replacing Compadre Stadium in southeast suburban Chandler).

American Family Insurance has naming rights for the Fields.

In February 2018, the Brewers announced plans for a major renovation of the facility.

The renovation included a new clubhouse building, renovation of the existing Brewers clubhouse, a newly constructed agility field, a new major league practice field, new batting tunnels, covered practice mounds, a new entry plaza, and new & refurbished parking lots.
