The Minnesota Twins have continued to do a good job on the minor league side of the organization. Not too long ago the Twins owned one of the top farm systems in the league. They then graduated the likes of Byron Buxton, Miguel Sano, Jose Berrios, Jorge Polanco, and others to the major leagues.
After that group formed the core for a playoff berth in 2017 the Twins front office has somehow already restocked the system and it is beginning to gain national attention once again. Most recently Baseball Prospectus released their midseason top 50.
