Those are franchise codes using retrosheet.org nomenclature.  The
current 30 franchises have roots all the way to the beginning of
baseball and it's easier to associate players with franchises
than players with teams since teams have migrated a lot and
making up a 3 letter code for each different team name and city
is confusing and most of all, it complicates things..

I could have reverse mapped MIN and 1912 to find out it was
Washington somethings if that info was necessary to display.
The reason I don't go pre-1900 except to pick up stats from
post 1900 players is because of all the dead franchises.  
1914/1915 is a challenge because of
that third federal league so there was a Chicago team here
not associated with any modern franchise yet they played
MLB class level baseball and some CHN players played for
them.
