I rarely miss taking my 9 yo DD to practice, but I couldn't make it last week. This week, HC pulls me aside and asks me to work with her on catching fly balls/pop-ups because he wants her in the starting lineup. So we did and the first thing I noticed was that she was placing her throwing hand behind her glove while making the catch. I've noticed some girls do this over the years and never understood why. I asked her to move her hand to a position where it would be easier to use to cover the ball after it enters the glove. She told me that the coaches showed her to do that at last week's practice. DW confirmed this. Before I go back to practice tonight, what is the logic with positioning the hand behind the glove when making a catch?
