It's not a deep list this year... I forgot about Pineiro. Some others (I'm looking it up now), in no particular order:
Shawn Chacon (or Tony Armas)
Fausto Carmona (maybe)
There are a few guys missing from the list, but most of them are either starters who won't be pitching in relief, or guys who I didn't think would be in the majors. As you can see this year's list kind of sucks. If your want to use a RP in your SP slot I would suggest Wood, Gregg, Pineiro, McClung... in that order.
