All of the men's pitchers do that. He is not unusual.
And my point is that women don't need the men to tell us that. We already know and have known for decades. If a pitchers wants to do something, I know I don't always force my opinions on them, but I let them know. The fathers are coaching their daughters today, so there is male influence on the not hiding.
I am tired of telling you that women's softball just a few years ago, the women hid the ball, They all hid it in the 80s. By that I mean no backswing and, if in front, keeping hands together in front. OK If you want to think that the Gods and Goddesses of softball male and female can only be happening since Jennie Finch.
They are making it illegal anyway (which I am against BTW). So the "as long"--if those few inches maybe up the circle make such a big deal, and you see it only rarely--is not a good thing to learn. The basic hiding that is a tradition in the sport, well that is a good thing to learn.
