I think that is clearly true given that he has not pitched above AA and really was not all that successful in AA even though he showed decent stuff.
I would not give up on Marte though. Hoping they can do something like finesse Song onto the 60-day IL. That might be a "process" too. But really they should just be able to recall Plassmeyer or Ortiz or Uelmen. It is stupid that they cannot.
Edit - Looking at Lehigh Valley the guy I would want is probably McKinley Moore. This is his first AAA season and he was also very average in AA last year, but he seemed to take a pretty big leap forward in training camp. Big stuff and the command seemed to be coming together. Maybe we'll actually win the Adam Haseley trade! Of course after completely losing the Adam Haseley draft pick.
One more thought - Darin Ruf's DFA period ended yesterday and he was released. A right-handed power bat for the bench might be a good idea. Not sure we have the patience to wait for Pache, especially if Harrison is banged up.
