I've recently found that coming up with a pre-shot routine has helped me become more consistent with my shots. Nothing crazy like Dufner waggling.
I address the ball, step back with my front foot and take a half swing, open to my target, swinging below the ball (but not taking a divot of course) then close back down keeping my grip the same, check target one more time, and swing. Back foot stays planted in position for the most part.
It's a little nuance but gives me more confidence and seems to reduce pressure. Has helped tremendously on the range and the course.
Do you have a pre shot routine? Seen a unique one?
