Hey bud, I suspect there might be a bug with the BoSox historical minors timeline. I'm still getting the Oakland Oaks as an affiliate in 1953.
They are listed on the csv as coming in for 1938 but I can't find any record at all of them ever even being a Sox affiliate, and certainly not still one into the 1950s.
They were briefly a Yankees AA affiliate in the 1930s, but never part of the Boston system
according to BBRef.
Might be worth further investigation.
Cheers
