Yeah if Covey leaves it is for Lorenzen (vs. optioning Marte) not a hitter.
And I'll take 24 year-old Castro and his .900 career major league OPS against LHP over 28 year-old career minor leaguer Weston Wilson or Kingery.
The real question is what they do when Pache comes back. Carry three RHBs on the bench (Sosa, Rojas, Castro? Or keep Cave and option Castro or Rojas. It would only be for a couple of weeks probably. So none of this is really that important. But clearly yesterday's deals indicate a willingness to carry both Rojas and Pache (and let them face RHP). But that also makes Castro (or any other RHB you want to romanticize in AAA) redundant except for his power (and position but they really don't need that either).
The minor leaguer I'd like to see is Muzziotti.
