I definitely complain, even when they don't score!
why? well, I subscribe to the school of thought that there's basically no such thing as "clutch" pitching and hitting, and that in the long run putting runners on base will lead to runs being scored against you no matter how "good" you seem to be at stranding them for a few starts.
case in point: take a look at Kaz Ishii. he has a godawful WHIP, and he started out last year a lot like this year - but eventually his luck ran out and he started getting hit really hard (and not just in the face). the same thing will happen to him this year if he keeps walking 6, 7 guys a game, and the same thing will happen to Escobar if he keeps allowing baserunners.
now, I should add that giving up 12 hits with 0 BB is generally a much better sign than 5 hits with 7 BB like Kaz enjoys doing, and Escobar's high K numbers are also a positive sign, but just as with Kaz, they are the only thing keeping him afloat - if he runs into a tough lineup he could get massacred very easily.
he's probably not worth too much now, but if he had another good start I would try to trade him to someone desperate for strikeouts and with a short memory about escobar's prior control problems
