Frederick Keys

The Frederick Keys are a collegiate summer baseball team of the MLB Draft League. The Keys are based in Frederick, Maryland. The franchise is named for "Star-Spangled Banner" writer Francis Scott Key, a native of Frederick County. A new team mascot "Frank Key", short for Francis Scott Key, joined the current mascot, a coyote named "Keyote", at the beginning of the 2011 baseball season. The team is currently owned by Maryland Baseball Holding LLC, after being purchased in 2006 from Comcast Spectacor. Home games are played 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.
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:
Debut.
The team was founded in 1989 when the Baltimore Orioles decided to move their Class A 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 (including a seven-inning perfect game by Dennis Burlingame) 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 (excluding rehab related transfers). 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 Keys have played in the Carolina League Championship Series, the Mills Cup Series, five times. Four series were against the Kinston Indians, while the series in 2007 was against the Salem Avalanche. They won their first series in 1990, defeating the Indians three games to two. They won their second cup in the 2005 season, defeating Kinston three games to two at historic Grainger Stadium in the best of five series. They were swept by the Indians in 2006, 3 games to 0. They won the 2007 series against the Salem Avalanche three games to one. They defeated Kinston in the 2011 series three games to one.
