The Frederick Keys are a Minor League Baseball (MiLB) 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.
