When I used to use a semi-western grip I could easily hit this shot along with a down-the-line forehand but ever since I have switched to the eastern grip I just can't seem to hit those cross-court shots anymore. I don't know if it's my footing, my form or my lack of spin on the ball but when I try to go for the shot it either goes to the middle or just about a little less than halfway on the left side of the court where the cross court shot should go. I'm just not getting the angle that I want. My down-the-line forehand with my eastern grip is flawless and easily executed though. Any suggestions or tips will do. I'm up for trying anything. Oh yeah, I'm right-handed.
It is all about the timing and hitting it more inside your zone to create a natural angle for yourself. Unless the ball is just sitting there, I honestly wouldn't try to "windmill" the ball by hitting it so far away from you unless you have a lot of wrist action to compensate.
When practicing or warming up, just take it slow and almost push it cross court by hitting it early and making contact inside the racket. Little by little should feel more and more natural. Other than that, you need to work on using your wrist because it helps A LOT especially with low balls.
