Kensing, Wells, Hanrahan, and Mock should be sent down, and Bergmann, Clippard, Preston Larrison and...oh jesus, i forgot the 4th guy's name, but they should all be called up to replace them.
stop worrying about their freaking Options. nobody is going to claim Hanrahan.
Colome is the 4th guy.
call up Bergmann, Colome, Clippard, and Larrison and make it clear that if they do not throw strikes, they will be gone just as fast.
