I was wondering about the Pirates. Turns out that the Pirates were founded in 1881, but originally played in the American Association, didn’t join the National League until 1887. Phillies have been in the National League since 1883.Without looking it up, aren’t the Reds older and longer tenured?
After Sluggo mentioned the Reds, I checked. The Reds didn’t join the National League until 1889, in the American Association in 1881. The Reds have no connection with the Cincinnati Red Stockings, the first pro team.
