Just trying to follow up on some of the minor leaguers on my fantasy teams.  I see that Stetson Allie, Sammy Solis, and Ismael Guillon haven't played this year.  I haven't heard about any injuries for these guys.  Are they just being held back for cautionary reasons? 

(That is really all I have to ask.  But it seems I'm still a few words short of posting. This last sentence should just about do it.  Dang.)
