I have been having issues with my ball toss. A few years ago I decided to try to model my serve on aspects of Sam Groth’s, in a bid to get more leg drive and hip drive along with more shoulder rotation. I thought maybe his toss had been worked around the power producing aspects of his serve and therefore may be a necessary evil, so initially I tried to copy his tossing technique. I have a very flat first serve with a 12.30 ball toss and a heavily spun (kicker) second serve with an 11.30 ball toss. My first serve on a good day is my biggest strength, my second serve is quite vulnerable (to say the least) against high level opponents. Since I changed my technique I have been more prone to double faults due to errant ball tosses. I read on a previous thread here about “tossing yips” that you should keep your elbow (extension) and wrist (flexion) out of the action as when you perform the actions mentioned you tend to get rotation at those joints, at least the potential for it comes into play. Someone also mentioned that most people they’ve seen who start their action with the ball below hip height (like Groth) tend to have erratic tosses. This makes sense to me as a longer more deliberate pendulum of a tossing action is likely to be more accurate in my opinion. Does anyone have any words of wisdom on optimal technique for an accurate ball toss and/or drills that can improve your ball toss accuracy. There are good slow mo's of the Groth ball toss @ 1:22, 1:55, 2:31 (can people explain why this technique is prone to inconsistency as it seems to be).
