Updated Top 25 MLB prospects

Because I don't have enough going on right now, I thought this might be a good time to revisit my offseason pro prospects ranking and make some changes to the Top 25 based on graduations and early reports. The update is based on conversations with scouts and front-office executives about these players, but the basis is the more extensive work and larger samples that went into the offseason Top 100. If I moved a player substantially from that list, it's because something tangible has changed.

Any player currently in the majors is ineligible for the list since, should he stay in the majors the rest of the year, he'll lose his rookie status for 2012 and will no longer qualify for the rankings by January.
