My 15 year old son plays HS baseball and "attempts" to model his swing on the principles found on this site, Jack's "Final Arc 2" video, and an Epstein grounded hitting coach. I know there are some differences between Jack and Epstein, but IMO they concur on the basics. I have two questions and I fear my first Q is a byproduct of my second Q/concern. 1) When analyzing his swing on film, I noticed both wrists are cupped at the contact point. His swing appears to be on plane so I am hesitant to change this but would it not be better if the wrist of his lead arm be more straight than flexed back (what I call "cupped"). Isn't he losing power if the wrist of his top hand is flexed back (cupped) at contact. Is it better if both wrists are straight at contact? His grip looks fine but I think he is cupping his top hand somehow during the application of THT. He isn't rolling his wrists until after contact but batted balls that would normally be over the fence are falling short this year. 2) I start to worry when we focus too much on the "fine" muscles like the wrists instead of concentrating on getting the larger muscle groups(legs, hips shoulders) right and in sync. I do not want to get too mechanical with him at this age because I have seen very "mechanical" swings go nowhere as the speed of the game increases. Any feedback is appreciated.
