San Francisco Giants BP Jersey Help

[Copa]

Looking for any info on this one...have a feeling it's just a replica, but I have very little knowledge of what to look for in an 80s/90s Giants BP jersey...from a brief search, it looks like the wash tag on a genuine team issued jersey should be on the inside...also, with 27 being a retired number, unless this is a minor league jersey, it's probably not authentic...thanks for any input!

The Rawlings logo sewn onto a patch almost always points to a minor league jersey issue.

The Rawlings tag is a gamer style tag, circa 1990-1991.

Juan Marichal's number was retired in 1975.

Without digging too deeply, I would take an educated guess that this is an early 90s minor league issue.
