Making ball-first contact is the key to hitting crisp, consistent iron shots. Adding a little visual cue like this, simple as it is, can really help you do that.
Davis Thompson, who is in the top-25 on the PGA Tour this year in strokes gained/approach the green, says the technique he’s been working on will also greatly help your game.
If you’re struggling with solid contact, it’s probably a low-point issue. The low point of your swing is either two far behind the ball (causing you to hit chunks) or too far ahead of the ball (causing tops and thins). There are two common mistakes that cause those to happen.
