Jon has done a good job improving his loading and sequencing, as well as his right upper arm pull back in transition and his tendency to push his hips toward the ball in the forward swing. He reported in that he hit the ball much better in his sessions just after the lesson, and here instead of looking for new items to address I suggest he keep working on the same things. One thing he does that is quite important is a half swing drill where it is obvious that he deepens his pelvis to create more space for his right arm through impact. In the half swing he doesn’t have enough backswing length to get into trouble with the right arm, and the result looks great and will get him to the next level if he can incorporate that into his full swing.
