True, but he needs to be there over Pache, or really, Merrifield (also an AAAA player at this point). Dahl and Clemens won't be here much longer anyway. Clemens was headed to AAA before the Schwarber/Harper injuries and Rojas probably isn't going back which means either DFAing Pache or DFAing Dahl, and either way there's still not a spot.
It would be nice to give him a shot but I doubt there's anything he can do in 3 weeks that would convince the front office it would be any more sustainable than the other guys.
