I think these two Rafael Santanas are sharing IDs (or something).

Major League SS:

A 1976 league I created with v19 shows the minor league pitcher with the SS's major league ID (santara01), but with the correct minor league ID (santan003raf).
He shows with the correct minor league stats but with the SS's major league stats.
A 1980 league imported only the SS.
