Probably some of this. I wouldn't be surprised if there's a certain amount of taking steps back on the developmental side too, forcing kids in the minors to spend more effort controlling their FB. I'm not sure what made Berrios so hittable in the majors last season, but I am not too worried just yet if they want him to get a few more starts in to help reinforce the new behaviors they are trying to teach. I doubt, at this point, it has anything to do with the WBC. That may have cost him a spot this spring, but once that decision was made, Berrios is now in a position where he has to earn it. I think the retaliation/punishment angle is way overblown.
