I am right-handed and am now re-engineering my serve based on instructions gathered from many sources. It is working on the ad side. But on the deuce side, the serve often lands long in the wrong court. Where does the left toe point at the beginning of the serve? I point it to the right net post in the ad court. But doing the same in the deuce court requires a lot of body rotation. I am pointing it somewhat to the right of the backhand corner of the opposite deuce court. Even then, the serve is going wide. I am tossing to 1 o'clock (in front of the left toe) in both courts. Is there a different swing motion in the two courts?
