Team History[edit]
The Frederick Keys began play in the Class A Carolina League in 1989 when the Baltimore Orioles relocated their affiliate, the Hagerstown Suns, to Frederick, MD. The club had been an Orioles farm team for its entire existence. The Keys have won league championships in 1990, 2005, 2007 and 2011.
They are named after famous Marylander Francis Scott Key, composer of "The Star Spangled Banner," who was born in Frederick County. However, during the seventh inning stretch, fans listen to the much more entertaining "We're the Frederick Keys" and are asked to shake their keys.
The Keys lost their MLB affiliation in the minor league reorganization of 2021 and subsequently the Frederick Keys were a member of the MLB Draft League, a summer collegiate league. On August 1, 2025, Attain Sports, owners of the team, announced that they would return to affiliated status in 2026 as a member of the South Atlantic League, switching places with the Aberdeen IronBirds, who would take over their spot in the MLB Draft League.
