I've been working on something similar in my game for most of this season. I'm right handed and had lost some distance and tended to hit the ball high & right on my poor shots.

After much self-analysis (hips not clearing quickly enough, closed face, alignment issues, ball position, etc) I finally went to the local pro. He identified a poor release of the hands and suggested that I try to keep the dominant right hand much more passive (just there for the ride, he described it as).

I didn't play tennis to the extent that I could bring that experience to my golf game, but I did play an awful lot of table-tennis in my younger years, and later in life with my kids. The pro suggested I try to use a backhand top-spin stroke left-handed............ works an absolute treat for me. Not only did I regain my distance, I actually increased the length a little.. lovely ball-flight with a touch of draw.

I must point-out that this only works for me if I swing smoothly with a light-grip.... any tension (first tee in a comp, pressure shots over water, etc) and I am prone to force the left-wrist through a little too quickly, resulting in a folding of the wrist............. not good at times .
