Cy Sloan Stadium was built in 1939 as a Works Progress Administration Project. Originally called Harmon Park Stadium, it was re-named for long-time Waurika supporter Millard Earl "Cy" Sloan.
Sloan was a member of the Waurika Lions Club, Sportsman's Club and Waurika Quarterback Club. He was instrumental in replacing storm-damaged lights at the stadium and also helped on Friday nights cheering in the stands, helping on the practice field or assisting with the sideline "chain gang".
The stadium holds approximately 1,300 fans.
