My 9 yr old has put in a lot of work over the last yr. We bought Hillhouse's video and watched online clinic. Everythings lookn good, stride and circle straight. Using gravity to finish. good finish. Stayn open (most of time) until release. starting to get good rotation on ball, popin the glove and Striking girls out. In the off season should we work on the flip change, peel drop, or should we wait till she's older/more experienced?
