During my last two tennis matches, I've noticed that my left hand will let go of the racquet during the follow through of my two-handed backhand. I've never noticed this happening before and would like opinions on what stroke flaw leads to this. It may be nerves or getting tight at certain points in the match. I was sort of guiding forehands in and also shanking lots of backhands. I settled my backhand down and was relying on it to keep me in the match. It was around that time that I noticed my left hand flying off the grip during the follow through. I am right handed. As best I can tell, the hand flies off the racquet right after contact is made as the follow through begins. Very frustrating and not sure why I am doing this all of the sudden.
