This is another example of an excellent swing with weakness at impact caused by a variety of factors which have to be traced all the way back to the beginning of the motion. We don’t have to bother with Jon’s set-up or grip, as they look fine here. We can, however, start with the takeaway, as the club comes back a bit closed and under the shaft plane line. It is not mandatory to have a perfect takeaway, but when you look at how the swing progresses you can see that it would be a good idea to change the pattern right off the bat by getting the toe of the club a bit more up and the clubhead elevated more up onto the plane line. Jon gets the club slightly behind him early, then in correcting that crosses the line a bit at the top. In transition the club kicks back but not quite enough, and then it continues to shallow late in the downswing, which causes it to come in under plane and a hair in to out. This approach leads to some flippiness at the bottom as the face needs to be squared so the shot won’t bleed out to the right. Jon’s misses are solid left and weak right, which makes sense since most good players (Jon’s a scratch and plays in high level amateur events) will overcorrect, causing the left miss, then correct that miss by holding off the face and hitting it to the right.
My thought here is to get the club to point a bit more left at the top. Although the more important factor would be the attempt to squeeze the arms in more aggressively (both right and left) and to actively attempt to flatten the shaft early in downswing by leaning it back on the right index finger. Once the shaft gets flat and the face is open the rest of the downswing can be a steepening feeling, which when combined with the squeezing arms and the thought of driving the hands more in front of the ball and exiting left would create more late lag and allow for more sustain in the hands through the impact area even as the face closes aggressively. Punch shot drills are always good for impact issues, and here I show myself hitting a pre-set punch with a back and forth rehearsal.
