Our DD has a pretty typical story of being a star in 10U this past year and just made the switch to 12U with the bigger ball and longer distance this fall. Seemed to transition well, but ran into eye-opening need to make some changes in her path. We love her PC, but she said most 12U hitters would not be able to catch up to DD's velocity, but would only need to use more movement pitches down the road as the girls get older. This didn't turn out to be true, because DD got hammered in fall tournaments. It was like batting practice for some of these hitters! I know this is typical for girls transitioning to the next level, but this exposed a big long term problem to me. Our DD is an early grower and will not grow much more beyond the next year. I have been reading all the stickies and threads about I/R and brush Interference and believe this is the path she needs to take to improve her long term picture. I understand it and value it, but how do I explain the basics of it in a simple way to my DD and rest of the family? Would someone be able to provide a list of the basic reasons why girls have a better path switching from HE to IR? I feel like the threads are so detailed, which is great, but i don't know how to describe it in a more surface level way. While no one in our club takes the same amount of pitching lessons, all of the older pitchers and all of the coaches (including even our high school coach) teach HE. I feel like other families will think we are crazy for making a change. To them, DD's mechanics are the best in the club, but now that I know they are HE I can't help but see problems and feel concerned! We also have a younger daughter that we would like to just start right off the bat with I/R mechanics instead of HE, but it will be a very eyebrow-raising and confusing move to people in our club who do not follow this DFP resource. Any tips would be very appreciated! Thank you to this wonderful community, because it has served as an amazing amount of guidance as we have embarked on this pitching journey in our family. I don't know what we would do without it!
