AAA Pitchers that may be worth a look (no particular order):
Zack Kelly - bullpen arm, 423 OPS, 27 years old and not much more to develop (532 OPS last season in WOO)
Kaleb Ort - WOO's closer, had cup of coffee last season, 487 OPS, 30 years old see above
Seabold - if Pivetta continues to falter, does it make sense to bring Seabold up and keep one of Houck/Whitlock in the pen?
Schreiber - pitched well when called up this year in place of Houck, 642 OPS
Feltman - "closer of the future" has been ok this year, has a k/bb ratio moon would like, probably not quite there yet
