if they control themselves enough to not say anything I just ignore it. I dont know really what you mean by exagerated, if she's stomping around that would be diff.. but just a look where I can tell she doesnt like the call - I let it slide. They are working hard. Ive never had that happen to where I would even warn em... and I've had a few pitchers who argue the call with their faces. A couple of batters give me the evil eye too. Evil eye is not a good thing to give me if youre a batter.. unless you enjoy a super duper theatric sell out on your strike out
.. but for the pitcher .. I just let it slide.
