think about your logic here for a second...if your hips are opening faster than your wrists, whatever that means...but if they are and you are 'snapping the bat head around' then why would you be getting jammed? that makes absolutely zero sense at all, if anything you would be early and hitting the ball way out in front and off the end cap
you should listen to the people that are telling you that you are diving in towards the plate. if you are standing in the box and the handle of the bat isnt over the plate, yet when you swing, the handle is over the plate, then it sounds like you are moving closer to the plate at some point during your swing, wouldnt you say?
