Jeez, are you paying attention? I never questioned VV coming up, just who was sent down. The pen will also need a good arm tomorrow and the following eight days when Fields is in CC.
I don't know what is so fucking hard about this, or why the proposition is so out of bounds. Simply put, who has helped win more games for the Astros recently, Fields or Carter or Valbuena? If Fields as an answer to that question is at least plausible, why is it also not plausible that he will help them win more of the next 10 games?
Ok, look at it from this POV...
Right now tha Astros are carrying 12 pitchers on the 25-man roster. That leaves 13 position players/hitters. They use 9 of them each game, leaving four on the bench. It's common sense to not use your backup catcher to PH or sub defensively...if your starter gets hurt late, and you've used the backup to PH, you're SOL. That leaves 3 on the bench, and if someone is banged up (Rasmus, for instance) or I'll (Gomez, anyone?), you're backed into a corner of having a pitcher PH.
As others have said, Fields has pitched three of the last four nights. He's NOT going to available to pitch again for a few days, so what waste the roster spot? With Sept. 1 call-ups less that 10 days away, he's back then.
Better to have a fresh McCullers and a fresh Velasquez for a few days, than to hang on to an unavailable Fields.
