The Tengen games have mapper 4 compatibility code in them, in particular the write to the mirroring register A000. So both variants are technically correct, though it's probably better to have the bootlegs use the same designation as the original games whenever possible.

I recalled RBI baseball not having the mapper writes to select mirroring.

Had you checked instead of recalling, you would have discovered that it does have the Mirroring write, at PC $F008.
