Thing is who do you pull? Julio? Wood? Santana? Personally I'd keep Floyd down a little longer and make sure he's 100% warmed up and good to go. Harang being on fire lets us take Floyd slowly. Maybe some team though will be super desperate for a pitcher and will swap us a BP arm for Harang.
Pretty much my take on it. Minor will replace Hale as soon as he's ready. I would ride the Harang until he's proven he's not up for the challenge anymore. Then I would let Floyd slide in.
