I don't mean to beat the dead horse on this...we've been over it a few times. Yes, some pitchers have done OK with Salty. But *overall* the staff ERA was a run higher in 2011 with Salty than with Tek, and a run higher in 2012 with Salty than with Shoppach.
Anyway if they keep Salty for 2013 we'll have another chance, to compare his CERA with Ross's.
