I have noticed this as well. On this particular swing, it's almost an anomaly for her that she gets extension (and an adjustment to outside pitch) because a challenge for her has been the rear arm being trapped along the side. I think her progress in the use of her core and where her center of mass stays is helping regarding the arm trap - BUT -
It is, and has been clear that she has a bit of a cast. I am trying to figure out why? She understands TTB and the proper pivot point. It seems to occur in the initial launch. What is your thought? Would a focus on early palm up/palm down help? Am inside the ball emphasis? Thoughts?
You use an inward turn to load correct? This is a new adjustment correct?
