Clubface control can be a tough task to fix, especially if there is a two way miss. Common factors are the Grip, Wrist Angles, and Forearm Rotation, among others. In this case, lots of forearms rotation is being used to close the face.

Just practicing is the best way to control the clubface, and having launch monitor data at your disposal is very helpful. IT GIVES YOU THE CLUBFACE ANGLE AT IMPACT! Look at it. Study it.
