My key to straight irons
I think of hitting the ball with the back of my lead hand
There are several keys to good iron play, but none is more important than an under-standing of how the back of the lead hand works at impact. It's critical for accuracy and solid ball-striking.
Straight shots are hit with the back of your lead hand square to the target at impact. Crooked shots occur when the back of your lead hand is anything but square, because that hand mirrors the clubface.
All too often, I see my amateur partners slice or hook a routine iron shot off the planet without any idea why. Banana balls result when they hit the ball with the side of the hand leading through impact. Snappers result when they turn their hands over too much. In both cases, the back of the lead hand is compromised.
To improve your iron play, feel as if you're hitting the ball with the back of your lead hand facing the target, the shaft leaning slightly forward. This will help produce a nice divot on the forward side of the ball pointing directly at your target.
