From the Curve, via Pirates Prospects:
C - Tony Sanchez
1B - Miles Durham
2B - Brock Holt
SS - Jordy Mercer
3B - Jeremy Farrell
OF - Quincy Latimore, Starling Marte, Brad Chalk
Bench - Eric Fryer, Kris Watts, Shelby Ford, Jose Hernandez
SP - Bryan Morris, Jeff Locke, Aaron Pribanic, Brian Leach, Aaron Thompson
Bullpen - Tim Alderson, Tom Boleska, Anthony Claggett, Mike Colla, Michael Dubee, Jared Hughes, Noah Krol
This would mean that Chase d'Arnaud, Justin Wilson, Matt Hague and Josh Harrison made it to AAA. No Diego Moreno. I'd be surprised if he's going to AAA, but who knows. He may be hurt or they just decided not to move him up, which would be a setback. Obviously, Robbie Grossman is headed back to Bradenton, which isn't surprising.
Jose Hernandez is skipping a level, but he's already 25, so it makes sense to challenge him. It'd be disappointing, though, to see non-prospect Brad Chalk play much over him.
UPDATE by Charlie: Moreno has forearm tightness and will stay at Pirate City. Let's hope that doesn't turn out to be anything more serious. Thanks to commenter Woo!
