Nice post. Your players might be suffering from bat drag. Bat drag refers to when the body is turning but due some disconnection between the body structure and the arm/hand structure causing a lot of body created energy to not get to the bat....slippage. Grip and hand pressure can often play a...
To me, front shoulder flying open is usually the result of something in the hitter's setup, sequence (or lack thereof) or physical abilities that are mismatched. When the hitter gets beat by speed then their brain naturally says, "start earlier". Often this is associated with a long front arm so...
At toe touch, his hands are deeper than most....about over his rear foot. Longer swing and less adjustability to off speed usually results in more K and rollover grounders.
Backspin can help if the wind is blowing out but backspin hurts if wind is blowing in. Tilt to make solid contact more often....not to create backspin.
It looks she is over counter-rotating her shoulders. Players who do a lot of tee work often develop this flaw because their head and eyes stay focused on the tee location instead of tracking a pitched ball. Tee work is good but it helps to have them look out and visualize a pitch and only find...
As long as the bases stay at 60 feet, fast players with slap/bunt/hit skills will get on base more often which will always be valuable. Also, I agree with the notion that slapping isn't easier but it is more productive for fast, skilled players.
Not really a drill but emphasizing two cues helps with off speed.
- "Both feet on the ground at launch" will help prevent unweighting of right foot at start of swing....improve lower half timing for both soft and hard slaps.
- "Pull back with rear hand at start of cross" will help prevent front...
For side toss, it's very helpful for hitter to look at imaginary P and for tosser to use a verbal cue to help hitter start her sequence and visualize timing a real pitch. For example, we often use COIL-PULL-FIRE where hitter starts COIL looking out at P and tosser tosses after PULL and hitter...
Not sure but maybe it is related to her top hand grip. Seems to be deep in her palm instead of more toward the fingers. Deep in palm can restrict/interfere with both barrel speed and direction for some players.
Is it helpful for clearing the body so the hands can attack form inside? Is it helpful for COM to drive forward and then away from the plate to create Nyman hook? Is it simply just quickest way to turn the hips? I am curious as to why it isn't talked about more since so many great hitters do it...
Some great hitters seem to often use their hips in a manner that causes their back foot to move "forward and behind" thru contact. I see the rear toes moving under the rear heel as the foot moves "forward and behind". Many youth hitters seem to have the opposite movement where the rear heel...
Looks like an "around" swing due to her rear leg/hip turning on a path closer to the plate. If she can get that rear knee/hip to turn without moving closer to the plate then her lower half will be allowing her upper half to attack the ball more from the "inside"...yes, even for an inside...
Can help with the lean/posture but we mostly use it to promote getting the feel of hip coil. The muscles around the hip are doing the coil but the player can feel the effect in the foot so we have them transfer their weight mostly into the inside of the rear heel and feel their pinky toe push...
