I am a high school player. On my backhand side, I can normally get pace and placement on low backhands whether I hit top or flat. But once the ball goes above my waist, I can't seem to get either pace or placement or proper spin on the ball. If I open up early, I can go crosscourt with a modest amount of speed, but it is not very consistent or well-palced. With that stroke, I also can't go down the line with any accuracy or speed. As I play doubles, this handicap has killed my game. I've tried many of the usual fixes, but slicing high to low, keeping my shoulder in, stepping into the ball, or backing up to take it in a comfort zone....none of these have worked. If anyone has advice, it would be greatly appreciated.
