Freddy will be a good pitcher for years to come. Elite fastball (VAA, really positive run value and all that fancy stuff) and stirkeouts, but he is no ace. His secondary stuff is mediocre and whenever things go bad he lacks the composure to get out of his head and get results. I love him to bits but he is a solid number 2 at best.
This staff does not have an ace and, if Misiorowski does not get his stuff under control, I don't see one in the minors. Guys like Knoth and Wichrowski have potential, but it is too early to tell
