While that is a good way of handling the comment , I have another suggestion that works just as well, my Juniors have had great success with it when dealing with border line comments....After the catcher questioning the zone wait for an almost perfect pitch , call time , bend over like your going to clean the plate (make the motions like your are but don't actually touch the plate with the broom , the catcher will pick up on that subtle move) , look right at the catcher and say "Nice pitch eh ?" , "now you do your job I'll do mine" and resume play , you won't have to do this very often for the catcher to get the message , course it could be a little different up here too I'm not sure, we don't tolerate much questioning of the strike zone , in the US you let some of that go ?
