Frederick Keys to Rejoin Orioles as High-A Affiliate

Affiliated professional baseball will return to Frederick, Maryland, in 2026 as the Frederick Keys become the Baltimore Orioles' High-A affiliate after a hiatus since 2020. The Keys will compete in the South Atlantic League and play at a fully renovated Nymeo Field at Harry Grove Stadium, with $39 million invested in upgrades. The Aberdeen IronBirds, the current High-A affiliate, will remain in Aberdeen and retain their name but will transition to the MLB Draft League. The announcement was made by Attain Sports, and Orioles executives and local leaders celebrated the historic renewal of the partnership. This development restores Frederick's 30-year relationship with the Orioles and is seen as a milestone for the community. The Keys had played in the MLB Draft League after being cut from Minor League Baseball during the 2020 contraction.
