A bigger issue is the logjam at pitching in AAA.
Right now, barring injury, Nola, Eickhoff, Velasquez, Hellickson, Buchholtz is your starting rotation.
I don't think they're going to move the young starters to the bullpen right now, given Benoit, Gomez, Neris, Ramos, Rodriquez, Neshak and Garcia.
Plus they still have Mariot, Murray and Hinojosa, and Aruno should start the season at Lehigh.
Lehigh SP: Eflin, Thompson, Asher, Appel, Pivetta, Lively and Morgan, the only lefty
Pinto and Viza may repeat at Reading with Eshelman, E Garcia, Anderson, Richy and Leiter
