I have noticed that players trying to check a swing fail to do so a significant fraction of the time. It has occurred to me that there might be a better technique than just using the muscles that control the wrist to try to stop the angular momentum of the a swing. I would appreciate any comments from a coach about the technique I describe below. In particular I am interested if any coach has ever seen anyone try this or a similar technique, and if so why it was not successful. I am assuming it it had been seen to be successful, more batters would be using it.
For a right-handed batter, when the batter wants to check a swing he should loosen his grip on the bat with his right hand just enough so that the bat slides along his right hand, and as his right hand moves towards the head of the bat, the head of the bat will be controlled so that the check swing will be successful.
For a left-handed batter, he would loosen his left hand in a similar fashion.
