I hope we don't need an answer to this any time soon...

This is taken straight from Blue Notes:

With all that's happening on the Perez front, it'll actually be
more interesting to see what happens if Sele pitches poorly.
Then what do you do? How many bad starts will they give Sele,
or Jae Seo for that matter, before feeling the need to put Odalis
back in the rotation? Just some fun stuff to think about.
The first order of business, assuming he can't be traded,
would be actually getting Perez into a game,
just to see where he is.

As you might remember, I was not entirely sure whether demoting Perez to bullpen was a good idea in the first place. Hope all three guys (Sele, Perez, Little) prove me wrong :).
