Do you check your clubface before you set up to the ball? A square clubface is critical to hitting the ball at your intended target. It's very easy to overlook the position of the clubface, especially because it only needs to be open or shut a tiny amount in order to have a negative effect on your ball flight.
There's a few different reasons why your clubface may not be square. If you waggle the club a lot before you settle into the shot, the club cluld be moving in your hand without you realizing it. Another likely culprit is alignment. I would say that almost all the golfers I see with a shut clubface do so because of their alignment. They are self correcting for the fact that they are misaligned.
Watch today's video for some tips on how you can always make sure your clubface is square to the target.
