I am going to speak only of my son's baseball pitching experience here, but I studied this carefully during his HS and college, and it seemed to me that the majority of time when a pitcher tried to throw off the plate on 0-2 they ended up walking the kid. This strategy worked at 12U but didn't work well after that. I just never saw that many kids swing at pitches off the plate. Many many times, then the pitcher would have a hard time throwing a strike for a pitch or two, then they would be frazzled because they let it get to 3-2.
That could very well be the case. However, I have seen just the opposite in high school and college softball. An 0-2 or 1-2 riseball seems very difficult to lay off. In travel ball I had my catcher call the pitches. She would often call something just off the plate, and at times, was able to expand the umpires strike zone as well. Or so it seemed.
