GM’s inquiring about “Arms” in the Pirates system

GM Neal Huntington is showing an interest in moving pitching prospects for immediate help at the major league level, according to major league sources.
James Taillon, Stetson Allie, and Luis Heredia are off limits but everyone else in the system is said to be in play under the right circumstances.
Most intrigue from GM’s is said to be on the Pirates 2009 draft class.
8th round pick Colton Cain is a name coming up quite often around the league.
