Pirates Prospects has a list of players who will participate in instructional leagues this fall. There are going to be a ton of prospects, including Jameson Taillon, Starling Marte, Stetson Allie, Luis Heredia, Zack Von Rosenberg, Colton Cain, Nick Kingham, Ramon Cabrera, Eleyvs Gonzalez, Brandon Cumpton, Zac Fuesser, Zack Dodson, Cesar Lopez, Yhonathan Barrios, Willy Garcia, and Mel Rojas Jr. In addition, there will be a ton of 2011 draft picks, including Gerrit Cole, Josh Bell and Alex Dickerson.
There are also some players I wasn't familiar with, including some Latin players and someone named Jin-De Jhang (who, I gather, signed with the Pirates last month).
