Pronation on a kick or slice serve.

[TennisDawg]

I grasp the concept of pronation on a flat serve. I understand the edge-on idea just before you pronate and hit the ball. I have a decent kick serve and slice that is very reliable and agressive, however I don't pronate when I hit those serves. I am just curious why would you want to pronate on a spin serve. It could be I've missed something and like I say I don't pronate on spin serves and don't feel I'm losing any thing by not doing it. I've tried finding info on line and pronation is discussed but on flat serves as far as I've been able to research.

Should one pronate on a kick or slice serve?? Serving experts/doctors or others with some knowledge on this are welcome to respond.

Thank you

There is pronation (and ulnar deviation) on a kick serve, it occurs later than for a 'flat' serve and the path of the racquet continues out to the right (for a righty) and the arm finishes roughly parallel to the baseline (see frames 8/9 below)...

You are pronating on your slice and kick serves at least up to contact. But, you may not be pronating much past contact depending on your technique. Some players allow their wrist to release and snap down at contact, some swipe across the ball by continuing their pronation through contact.

Thanks, what I'm sure I'm doing is ulnar deviation on a kick serve or even on a slice serve. Brushing up on the ball from 7 to 1 oclock for the kick serve and from 3 to 9 oclock on the slice. I get a lot of spin on the two serves, but I'm not able to pronate, I can on my flat serve, but not the kick or slice. My service technique seems fine, though.

Thanks for the pictures, this is the first time, I've ever been able to get this clarified. It may be very difficult for me to change, I'm gonna give it a try, but it just may not be doable for me.

Can I use a similar pronation as shown in frames 8/9 for a slice serve (assuming I change toss to the right)?

Are there any pics for a slice serve pronation as compared to a flat serve?

I believe, but am not certain, that this is a kick serve. Note how complex the motion is.

Couple years ago, I agreed with you. I pronated on flat serves, but chopped upwards at the twist serves, resulting in head high bounce, but at ridiculously slow speeds around maybe 50 mph.
So I needed to add some pace. Switching to more backhand grip, I swung upwards at my twist toss using full pronation, like a flat serve...but with a more backhand grip. Got more rackethead speed, more bite on the ball, and a much faster twist serve, now maybe into the 60's.
A gain of maybe 10 mph, considering the slow overall speed, is a huge difference, mainly to the returner.
