There is also a tendency to delay the backswing too long and then hurry through the shot. As a result this causes a leading with the elbow and the racquet face is exposed in an awkward and unsupportable angle. Start the back swing earlier by getting prepared for the shot and meet the ball out in front with the weight moving forward. Eliminate unnecessary motions on the backswing and utilize the non-hitting hand to bring the racquet back and turn the shoulders. Focus on the ball and allow the weight to transfer into the shot with the front foot pointing towards the direction the ball will be returned.
Shots go off target to the right.
To begin with, eliminate the horizontal forces by stepping out toward the intended target rather than feeling the pull sideways. Keep your shoulders in line with the path of ball. This will prevent the shoulders opening up. Stop the rotation of the hips at impact, this can be done by sending the non-hitting hand backwards or holding it on the back hip. The transfer of power will only happen from a solid base and the snapping motion provided by front side of the body.
