The first team to play at the fairgrounds was the Southeastern League's Meridian Scrappers who used the ballpark from 1937-1939. During their first two seasons, they were members of the St. Louis Browns organization. In 1939, they became a co-op team and in 1940, they changed their name to the Meridian Bears. In 1941, they changed their name again, this time to the Meridian Eagles and returned to the St. Louis Browns' umbrella. By 1942 they again were a co-op team. The league ceased operations due to the war after the 1942 season.

In 1946, the Southeastern League returned with the Meridian "Peps", which were members of the Brooklyn Dodgers association. The Peps represented the Dodgers for only one season before switching affiliations to the Cleveland Indians, where they remained from 1947 until 1948. In 1949, the team again went co-op and changed their name for the 5th time. Now, they were known as the Meridian Millers. They remained in the Southeastern League until 1950, when the league finally folded.

With the Class B Southeastern League permanently defunct, the Meridian Millers found themselves without a league to play in, and sat out the 1951 season. In 1952, a spot opened in the Class C Cotton States League, when the Clarksdale Planters ceased operations. Meridian hadn't played in the Cotton States League since 1929. They kept the name Meridian Millers, and instead, changed the name of the stadium from Fairgrounds Field to Buckwalter Stadium. They remained in the Cotton States League as a co-op team until 1955 when they moved to Vicksburg.
