By the way: this guy (“Ramon Herrara”) is Ramón Herrera. Herrera actually started the 1922 season on the Bridgeport Americans, also of the Eastern League, alongside Cuban Hall of Famer Joseíto Rodríguez, though it evidently didn’t show up in the guides. He must have played very little with Bridgeport (fewer than ten games) before moving to Springfield.
Herrera and Claudio Manela thus joined the Eastern League from the Negro National League at the same time, though Manela didn’t stick. Both were nicknamed “Mike,” for whatever reason. (At least Mike González was actually named Miguel.)
