Voth is, I think, "the poor-man's Erick Fedde". OK as a two-inning relief pitcher when he starts an inning, especially if it's not the end of the game. Clay should be taken off the 40-man roster as soon as someone -- our old Clipp -- is ready.
Machado, Aaron Sanchez, and Rogers should be lined up and sent to Rochester as soon as someone else is ready. Someone like Strasburg, I hope.
Machado's already in Rochester.
