I am interested in Yodeli's commentary that a pivot action is necessary prior to hitting with the right arm (triceps activation actively extending the right elbow). I can envisage the downswing pivot action throwing the left arm off the chest wall with a very assertive (very active) right shoulder thrust maneuver, and I can also envisage a more gentle right shoulder thrust maneuver that simply moves the power package assembly downplane, and into a mid-downswing position where the right arm can start to actively power the downswing via a hitting action. Which of these two options is recommended for a hitter?
