any "quick fix" ideas for my forehand that has suddenly gone awry? i can hit a rally ball fine, but my crosscourt forehand drive or angled winner attempt has really been off recently. notes: 1. my down the line forehand has suddenly become amazing, and even though it is supposed to be low percentage I am using it more and more. It has pinpoint precision to hit deep in the corner and I am super confident right now with it. 2. my right ankle was severely sprained a year ago, and there is a bunch of scar tissue in there now. it still hurts when I "crouch" down to get in good position. I think my problems are: a) improve strenght in core muscles.. back and stomach feel weak after 2-3 hours of tennis which probably inhibits my cross court shots most because of the twisting action involved b) i am standing up too much, and opening up my shoulder too soon because of my bad ankle, and also moving off my back foot too soon because of the pain -------- With those thoughts in mind, any ideas you can come up with to try and improve this shot for my next match. Most of my CCFH shots have been going long if that helps with ideas..... I am 4.5 with good strokes... but something has gone off with this shot. Right now I can hit winners only on the right half of the court... and my opponents are starting to camp out there once they realize I can't blast one cross court even when the court is open.
