I was reading some Golden Age Superman today, and there's a cool baseball story (Superman #23, from Vol. 6 of the Archives), in which the start pitcher of the Metropolis Ravens is helped out by Superman... I feel like Metropolis is has a different team later... but I don't remember what it is.

Then I know there's the Gotham Knights, and I think they're a rival team in Bludhaven.   

I also recall Tawny (from Capt. marvel) playing for the Detroit Tigers for a bit, but I don't know fi that was the Fawcett universe or not.

I thought this would be fun thread to work it all out
