Why would you use him in a big spot? We don't use Santana and Greene in big spots. It would give us the option too though vs a lhh portion of lineup. Minter's fWAR is 0.7 and FIP and xERA are good. His xFIP is high
Greene doesn't see the playoff roster either way.
I see it as a toss up between Santana/Minter/Muller.
With Rodriguez here I could see the need for a third lefty. If thats the case Muller is above Minter in my eyes in the pecking order. I've just seen Minter blow up all too often now.
