Kevin Reichard of Ballpark Digest reports that upper-level Minor League Baseball affiliations will be relatively unchanged by the new professional baseball agreement that takes effect in 2021. One notable exception? The Marlins (emphasis mine):
Three Triple-A teams—San Antonio, Fresno and Wichita—have been designated to move from Triple-A to Double-A’s Texas League or (in the case of Fresno) to what will be the Low-A Cal League. Taking their place: St. Paul, where the Minnesota Twins could affiliate with the St. Paul Saints; Sugar Land and Jacksonville, which will become the Miami Marlins’ top affiliate.
