Hi, I'm new here and I searched for this topic but I couldn't find anything on the subject. I am coaching high school tennis. Two girls who are pretty good players wanted to work on the slice (mostly for defense purposes as they are pretty steady baseline rallyers). They have a two-handed backhand, and I have a one-handed backhand myself, so I could use some advice on the subject. Basically, I tossed the ball from the ad side alley so that they could slice the ball crosscourt. I focused on stepping in, hitting from the outside of the ball, and extending the arm forward to hit through on the follow through. As is often the case, they sliced from the inside of the ball, plus the two-handed backhand means that it is harder for them to extend the arm forward on the follow through. So, even though they were hitting crosscourt, their balls sliced back into the center of the court. Here's a video to better illustrate what I am describing: http://www.youtube.com/watch?v=X9PtgPprR_Y Any advice would be much appreciated.
