My DD plays on a 10u club team. She is 11yrs old and is tall for her age (5'2"). At the start of the season she was swinging a 30" RT. At the request of her hitting coach we upgraded to the 31" RT. Both bats are older models (2006). She loves the RT because of the pop when she hits the sweet spot. During practice she absolutely crushes the ball. Coach pitch, soft toss, tee work, etc. However, she is struggling against live pitching in games. The pitching varies from inning to inning, game to game. Against slower pitchers she will use the 31" and the 30" against the "flamethrowers." When I take her to the batting cage (45-50mph) she can use either bat, but it does take her 8-10 pitches to get her timing down. Many girls on her team are swinging much lighter bats ... DeMarini Bustos is very popular. I know she has timing issues, but am wondering if the RT is making the situation worse. Thoughts? Any and all advice is appreciated.
