We moved our 8y old DD up to a 2nd year 10u and at first it was a STRUGGLE. Pitching, hitting, base running…. But she loved it, worked and worked, and by June had our second highest batting average and was getting good innings pitching. Fast forward to her starting her 3rd year at 10u, and those struggles pitching, hitting, everything she went through has her confidence through the roof. Having that extra year of pitching innings was huge for her. Learning how to work through a bad inning and such…She just played her first PGF tournament this weekend and threw great . Anyway, from our experience, if DD wants to do it, and it doesn’t kill her confidence, that extra year of pitching and hitting is great
