Excellent read from Ben Badler, including this:
"Between [Francis] Martes, Joe Musgrove, David Paulino and Michael Feliz, the Astros have an impressive collection of pitching prospects at the upper levels, even after trading Mark Appel and Thomas Eshelman to the Phillies. In the lower levels of the system, Abreu is separating himself as the next Astros pitching prospect to watch."
