Crystlemc, don't be upset. Screwball has and does make some very good points. There has been this perceived notion that swinging the arm back generates more speed. That is the biggest fallacy related to pitching. If therefore it is not true, then why in the world do it? There is no practical purpose. I know as a hitter, seeing the ball that much longer is a gift from heaven. I have noticed a trend in the women's game where more and more women are keeping the ball in the glove and I believe that it is in large part due to the influx of former men's players in the coaching ranks.
Starsnuffer, hiding the grip is not necessarily that easy to do and there are other aspects of pitching that could lend itself to the pitcher being picked. I have found that there are more girls becoming students of the game since the former men's players are getting involved. There is a lot of dancing and singing still going on on the bench, instead of studying other teams tendencies and looking for advantages on the field. JMO.
When my daughter was 10, she watched Bill Hillhouse's video on her own, went outside, and taught herself his motion as described (she was already pitching about a year at the time). So, it's so easy even a 10 year old could do it, and she's blond to boot.
I've since taught it to about a dozen other pitchers that have played for various teams I've coached since then. I don't insist that they use it, since I don't want to mess with the hard earned money daddy pays SusieQ who pitched for the D1 school down the street to teach darling daughter how to pitch, but I do give them the tool to put in their toolbox.
Once you explain WHY it's important to hide a pitch, and teach them how to pick pitches from the kids they're playing against, most of them get it.
Teaching something is not forcing its use, we need to remember not to confuse that.
Comparatively speaking it's easy to teach girls to hide the grip. Many have absolutely no concept of hiding it and their pitches are blatantly obvious. So any measure of hiding it makes it look even more hidden to the average girl softball player. Even a simple thing of getting the grip inside the glove instead of on their hip is a major way of hiding the ball that many girls do not do. The simple act of not making their pitch obvious goes along way to hiding the ball at certain levels.
