The Aberdeen IronBirds are a Short-Season A classification affiliate of the Baltimore Orioles. The IronBirds play in the New York–Penn League and are based in the city of Aberdeen in Harford County, Maryland.
The team is currently owned by retired Oriole Cal Ripken, Jr.. Ripken Jr. purchased the team, then known as the Utica Blue Sox, and moved them to his hometown of Aberdeen in time for the 2002 season. The IronBirds play their home games at Leidos Field at Ripken Stadium, which is visible from I-95. On August 16, 2006, the IronBirds played host to the New York–Penn League All-Star Game. Leidos Field at Ripken Stadium was also used for the Cal Ripken World Series in 2003 and 2004, forcing the team to go on extended road trips, 20 or more games, during the youth competition. The Cal Ripken World Series moved across the street to Cal Sr.’s Yard in 2005.
