I've been going through my minor league rosters to trim them down and I found that one of the players I signed in this league's first IFA period (Manuel Marcos) started going by a different name (Manuel Margot) and at some point a duplicate player entered this league under the new name (he's currently on the Rangers' roster).
Here is a link to a Baseball America article referencing the name change:
