Skirrow is one to watch, while all the attention is on the big four, Phillies also need to start developing some pitching depth in the organization, guys like Falter and Sanchez, who can fill in as middle relievers or #6 starters with at least some upside. Up to now, most of their marginal pitching prospects have died in Reading or Lehigh.
These are the guys that let you NOT make trades like the one for Gibson and Kennedy.
