Frederick Keys


The Frederick Keys are a Minor League Baseball team located in Frederick, Maryland. They are the High-A affiliate of the Baltimore Orioles. A new team mascot, Frank Key, joined the current mascot, a coyote named Keyote, at the beginning of the 2011 baseball season. The Keys were purchased from Maryland Baseball Holding, LLC by Attain Sports and Entertainment in January 2022. Home games are played at Nymeo Field at Harry Grove Stadium. Prior to Major League Baseball's reorganization of the minor leagues following the 2020 season, the Keys were a Minor League Baseball team that served as the Class A-Advanced affiliate of the Baltimore Orioles from 1989 to 2020. On August 1, 2025, the team announced that it would once again serve as the Class A-Advanced affiliate of the Baltimore Orioles starting in 2026, replacing the Aberdeen IronBirds.
The team and one of its mascots, Frank Key, are named after lawyer and Frederick County native Francis Scott Key, the author of the poem "Defence of Fort M'Henry". "The Star-Spangled Banner", the American national anthem, is the first stanza of the poem set to the tune of "The Anacreontic Song".

History

Early professional baseball in Frederick

Frederick was one of the founding members of the Blue Ridge League, which existed from 1915 to 1930. The team, which went by the names of Hustlers, Champs and Warriors, won league championships in 1915 and 1921. Games were played at the Frederick Fairgrounds until 1924 when McCurdy Field was built. With the collapse of the Blue Ridge League in 1931, it would be several decades before professional baseball returned to Frederick.
Frederick players from this era who were major leaguers:
  • Clyde Barnhart: 1915, 1916, 1917
  • Tom Connolly: 1915
  • Bill Lamar: 1915

    Minor League Baseball (1989–2020)

The team was founded in 1989 when the Baltimore Orioles decided to move their Class A Carolina League affiliate from Hagerstown, Maryland. The city of Frederick convinced the owners of the then-Hagerstown Suns to move the team to Frederick and promised a 4,000-seat stadium to be built for the 1990 season. For the 1989 season, the Keys played at McCurdy Field, a Babe Ruth League stadium, while waiting for the construction of the new stadium to be completed. The Keys opened by losing both ends of a doubleheader against the Durham Bulls. Their first win came on April 11, 1989, with a 3–1 victory over the Kinston Indians in the Keys' first-ever home game.
Only two players in Keys history have been transferred directly from Frederick to the Baltimore Orioles. On September 3, 1996, Eugene Kingsale's contract was purchased by the Orioles. On June 11, 2005, Jeff Fiorentino's contract was purchased by the Orioles in order to replace the injured Luis Matos.
The 2020 Minor League Baseball season was cancelled due to the COVID-19 pandemic. The Keys did not receive an invitation to remain in affiliated baseball as part of the 2021 reorganization of Minor League Baseball, and instead joined the newly-formed MLB Draft League.
