Frederick Keys
Minor league team named after Francis Scott Key.
Last updated
The team was founded in 1989 when the Baltimore Orioles moved their Class A affiliate from Hagerstown, Maryland.[1] Frederick promised a 4,000-seat stadium to convince the owners of the Hagerstown Suns to relocate.[1] The Keys served as the Orioles' Class A-Advanced affiliate from 1989 to 2020.[2] In January 2022, Attain Sports and Entertainment purchased the Keys from Maryland Baseball Holding, LLC.[3][4]
On August 1, 2025, the team announced it would return as the Orioles' High-A affiliate starting in 2026.[2] The team and mascot Frank Key are named after Francis Scott Key, author of "The Star-Spangled Banner".[5] In their opening doubleheader, the Keys were defeated in both games, with Dennis Burlingame throwing a seven-inning perfect game against them.[1] The franchise's initial victory occurred on April 11, 1989, when they beat the Kinston Indians 3–1.[1]
Following the 2020 minor league restructuring, the Frederick Keys became a member of the MLB Draft League.[2]
What the cited sources add
The Baltimore Sun report notes that the Keys' removal from affiliated baseball largely stemmed from a facility needing modern upgrades.[4] Attain Sports and Entertainment, based in McLean, Virginia, also bought the Bowie Baysox in the same transaction.[4] The new owners stated goals of increased community outreach, stadium enhancements, and a focus on fan experience.[4] The Blue Ridge League historian Mark Zeigler authored a book on the league's early years from 1915 to 1918.[6]
