Credit where it’s due, I “borrowed” the idea for this article from Max Rieper at Royals Review.
I’m going to do this a bit differently than Max did. He listed all former Royals active in pro baseball — minors or majors — and sorted them by hitters and pitchers.
What I’m going to do here is limit this to players currently on active rosters (or injured lists) for the other 29 MLB teams, and sort the list by team. Also, for this list the former Cub must have played in at least one game for the MLB Cubs — just being in the Cubs minors isn’t enough (sorry, Daniel Vogelbach, Dylan Cease, Eloy Jiménez and others!
