using a little slice on the volleys is going to give you the extra control you need Hitting the ball too flat or trying to hit it with topspin will definitely lead to
inconsistent volleys. However in order to do so it’s very
important that your not swing down on the ball,
that you not tried to cut it too much. Simply, open up the racquet in a tiny bit
and hit through the shot. That will make the ball
rotate slightly and give you the need to control.
