Many golfers unhinge their wrists well before impact in an attempt to help the ball off the ground. This is called casting, like you cast a fishing line, and it usually leads to poor contact—fat or thin. For solid strikes, your wrists should not unhinge fully until after impact. Get a feel for this with my punch drill: Using a 7-iron, hit punch shots with an abbreviated finish, keeping your hands ahead of the clubhead well past impact (left). Hit 10 punches, then try some normal shots re-creating that feel.
