If Chapman and Bailey up, who down from the pen?

When this happens? Looks like Bailey is doing fairly well in Louisville. Who do we send down if Bailey and Chapman come up?

Bray and Springer......just a guess

Bray and Leak, its time to shut him down.

Chapman for Springer, if he goes to the DL. I wouldn't send Bray down right now, not sure what I'd do with Homer at the moment -- how close is he?
