Thanks for the explanation. Let me just say, whether or not anybody thought I was implying this, that I don't think this is all on Barrett. Heck, it's probably mostly on Zambrano. If Z feels better, for whatever reason, with Hill/Soto/Blanco/whoever behind the plate instead of Barrett and puts up an ERA 5 runs better without Barrett than with him, then I'm all for giving Barrett the day off whenever Z pitches. The loss on offense will be much more than made up for by the better pitching.
