Yes, and expecting him to do so consistently from here on out would be foolish. To hold onto him because he could become a back of the rotation soft tossing lefty would also be foolish. If there is reason to think he has something else (exceptional control, a plus plus curveball, etc.,) then I would be more in favor of keeping him. Honestly, I haven't studied him like the Sox FO likely has, so I trust them to know his worth. He could simply be another Lenny DiNardo.
