Frederick Keys Rejoin Orioles as Affiliated Team in 2026

Affiliated professional baseball is finally making its way back to Frederick County, Maryland. Major League Baseball just renewed its partnership with the Frederick Keys, bringing them back as the Baltimore Orioles’ High-A affiliate starting in 2026.

That’s a big deal for Frederick. It ends a six-year stretch without affiliated minor league baseball in town.

Harry Grove Stadium is in the middle of a $39 million overhaul. The Keys rejoin the Orioles’ farm system, and fans can’t wait to root for future big-league hopefuls again.

The Frederick Keys: Back Where They Belong

Back in 2020, MLB’s sweeping restructuring cut 43 teams, and the Frederick Keys lost their minor league status. The team shifted to the MLB Draft League, focusing on amateur prospects.

That kept baseball alive in Frederick, but something felt missing for the city’s loyal fans. Now, the Keys are returning as the Orioles’ High-A affiliate, restoring their place in the local sports scene.

Frederick’s baseball story goes way back—over a century, actually, to the 1910s.

A Community-Wide Celebration

The news has everyone in Frederick County buzzing. Attain Sports CEO and Keys owner Greg Baroni called it a transformational moment for the team and the whole community.

For Baroni, it’s more than just baseball. It feels like a cultural revival for Frederick.

Orioles general manager Mike Elias agrees, pointing out the strong connection between Frederick fans and the Keys, even through tough years.

Frederick Mayor Michael O’Connor summed up the city’s excitement, calling the Keys’ return a sign of Frederick reclaiming its minor league baseball identity.

This partnership between the Keys, MLB, and the Orioles brings hope and opportunity for fans and local businesses.

Harry Grove Stadium: A $39 Million Facelift

The Keys are getting ready for their 2026 comeback, and that means giving Harry Grove Stadium a serious upgrade. The stadium, home to Frederick baseball for years, is now in the middle of a $39 million renovation.

They’re aiming for a better fan experience and making sure the stadium meets MLB’s latest standards. The upgrades include new seating, improved facilities, and a more modern look.

It should turn Harry Grove into one of the top High-A ballparks around.

A Legacy of Future Stars

The Frederick Keys have always been a place where future MLB talent gets its start. Fans get a front-row seat to watch young players rise through the ranks.

With the renewed Orioles affiliation, there’s even more reason to watch prospects develop right here in Frederick. That connection only strengthens the city’s ties with Baltimore.

What Happens to the Aberdeen IronBirds?

The Keys’ return as the Orioles High-A affiliate means changes for the Orioles’ farm system. The Aberdeen IronBirds, who currently have the High-A spot, will move to the MLB Draft League.

The IronBirds will keep their team name and stay in Aberdeen. This kind of shuffle shows MLB wants to open doors for players in both affiliated and amateur leagues.

It’s all about keeping baseball growing at every level.

Why Frederick Fans Should Be Excited

The Frederick Keys offer fans more than just exciting baseball. They bring community pride and a real sense of belonging.

There’s also a deep connection to the sport’s rich history. So, why should local fans start marking their calendars for 2026?

• A chance to see future MLB stars: High-A baseball gives you a front-row seat to prospects hustling their way up to the majors.
• An upgraded stadium experience: Harry Grove Stadium’s $39 million renovation will bring new, state-of-the-art amenities for everyone to enjoy.
• Economic growth: The Keys returning means more visitors in town and a boost for local businesses. That’s pretty exciting, honestly.
