Clay Ballard from Top Speed Golf explains how standing up through impact—or early extension—causes the clubface to open, leading to missed shots to the right. He demonstrates the Chair Drill to help golfers maintain butt depth and posture through impact, as well as a range variation using an alignment stick and board.
Early extension moves the hands closer to the ball, naturally opening the clubface at impact.
Trying to flip or cast to fix an open face creates unpredictable pulls and hooks.
Keep your lead glute pushed back against a chair or alignment stick through the downswing to maintain spine posture.
Staying in posture allows your wrists and arms to square the clubface naturally for straighter shots.
