The Hagerstown Suns Minor League Baseball team was established in Hagerstown, Maryland, in 1981. The Suns remained in the Carolina League through 1988. In 1989, team ownership purchased the Williamsport Bills franchise of the Double-A Eastern League (EL) and relocated the team to Hagerstown. The Double-A Suns carried on the history of the Class A team that preceded it. After just four seasons, the Eastern League franchise left. The Myrtle Beach Hurricanes franchise of the Class A South Atlantic League (SAL) relocated to Hagerstown for the 1993 season where they became the Suns and continued the previous Suns teams' history.
The Suns' lone league championship was won in their inaugural 1981 season.
