Wikipedia - Dayton Dragons

The Dayton Dragons are a Minor League Baseball team of the Midwest League and the High-A affiliate of the Cincinnati Reds. They are located in Dayton, Ohio, and play their home games at Day Air Ballpark. In 2011, they broke the record for most consecutive sellouts by a professional sports team, selling out their 815th consecutive game, breaking the record formerly held by the Portland Trail Blazers.

The Dragons came to Dayton in 2000 as the franchise was relocated from Rockford, Illinois. The franchise was previously known as the Rockford Expos (then Royals, Cubbies, and Reds). In 2021, the Dragons and 11 other teams that had previously competed in the Midwest League entered the High-A Central as Major League Baseball completed a large restructuring of the minor leagues. This was a temporary name change, with the historical "Midwest League" moniker returning for the 2022 season.
