It seems that every season major league clubs are calling up their top prospects earlier and earlier and 2011 has already proven to be no exception. On Thursday the Royals called up their top prospect in first baseman Eric Hosmer. But Hosmer is far from the first highly touted prospect to make an appearance this season. He joins a list that already includes Brandon Belt, Zach Britton, Jerry Sands, Trevor Plouffe, Tyler Chatwood, Michael Pineda and more. But it isn't usually the top prospects that we've all heard about who make the biggest fantasy baseball impact. It's those bounce back players who were forgotten about who usually step up and are the greatest of waiver wire acquisitions. So, let's take a walk around the minor leagues and see just who is positioning themselves to be on a big league roster in the near future.
