I've spent some time looking at various slice serve vids and it seems clear that many either don't pronate or do so after the ball has left strings. The no pronation group talks about the "dirty diaper" serve and in this video she clearly doesn't pronate and finishes with racket face pointing up. My question is do you pronate on slice and if so when?
Sorry but definitely pronating. How do you think a racket moving on edge will hit the ball if it doesn't open at some stage and what opens it except pronation? Slow it down even further by playing at 0.25 speed when the racket starts going up towards the ball and go frame by frame by using the arrow keys. You will see it.I've spent some time looking at various slice serve vids and it seems clear that many either don't pronate or do so after the ball has left strings.

Well let me say I feel it is pronation up to contact but that is where she seems to stop. The racket never continues to have strings face right. I feel i'm getting a better understanding that even if they finish pronating it is well after ball has left strings
Ian is right I noticed the pronation before I watched Ian’s video but he explained it.Don't believe everything you see on the internet:
EDIT: For those too lazy to get an education he specifically adresses the serena video above at 5:00
From racquet moving edge on to contact is pronation the rest is follow thru. Some players end up with racquet head facing right some don’t but that doesn’t mean they didn’t pronate. Going off track a little bit. I struggled with the edge on and contact for a long time. I read in a book that you delay the from edge on to contact, until the very last second. I found that very hard to do so I just make contact without thinking about it. It was bad advice. It doesn’t matter as long as you come in with racquet edge on.Well let me say I feel it is pronation up to contact but that is where she seems to stop.

@FiReFTW, I think they do not pull the racket down. The kinetic energy is directed by the pivot point at the shoulder and is enhanced by the gravity.
The speed bringing the racket down is more or less just a result of the effort put in throwing the racket up. The arm long axis acceleration thru the shot, will determine the amount of isr in the end and weather the face is pointing down or on the outside. Ofcourse the range of motion in the shoulder is restricted by the players moveability. Same effort will therefore give different results from player to another.

I've been making a concerted effort recently to pronate AFTER contact. I was never doing that before and always stopping at contact. It does make a difference in spin and sometimes power - I hit the back fence more often put it that way. (All dependent on my timing - my serve is still a work in progress).
My point is, I think players DO need to do more when it comes to pronating after contact but because it is becomes part of their muscle memory they don't even think about. Sometimes the amount of pronation will vary but I think this is because the player is not thinking about pronation per se, but the general trajectory and spin on the serve that the player wants to achieve. The pronation part after contact does need explicit attention..in the beginning, but obviously not when part of the muscle memory.
People are complicating and overthinking pronation. Pronation comes natural in a throwing motion, and after contact it is simply follow thru. Be loose, dont force it, and it will happen, magic
I think you're right. But I think I'm right too, in that for some players, like me, they have tightness in certain muscles which means unless they do the relevant conditioning exercises (I don't but should do), then they'll only ever be able to do so much.
For example, if you have tight shoulders, you'll need to hit a whole swathe of serves before you connect loosely. In the same way, if you have tight arm muscles, there is only so much you'll be able to pronate...
What do you think?
This pronation still is probably the most confusing and bipolar topic in tennis.
I think this topic is quite complex and interesting and very bipolar
We could also discuss the importance of the left arm (throwing arm), does it just fall down passive, or does players actively drive og pull it down to create more speed and power, just like with the forehand the left arm can be used to create rotation and is very important to the serve.
I am working with my coach to actively pull my left arm down to my stomach, to create momentum and more RHS, in his opinion this action gives more power to the serve than pronation but I hardly see this discuss here. People are too focused on the hitting arm. In a throwing motion the left arm is very important to create speed and rotation. In a serve all parts should be working together.

People say this a lot, and it's definitely true for some people. However, for a lot of people it's not true. Some people can throw reasonably well, but when they try to serve overhead it completely falls apart. I think if you learned to throw as a kid then it's probably a lot more natural feeling. Kids experiment a lot and many can learn a lot of things through experimentation and repetition without any coaching or teaching.
Even then, there are still a lot of kids that will only progress so far. When I was in little league in grade school, maybe 4th or 5th grade there was only 2 kids on the team that would play catch with me. The other kids complained that I threw the ball too hard. I just kept trying to tell them to catch the ball in the pocket and it wouldn't matter, but they didn't like my solution. So I ended up playing catch and warming up for pitching with the same two kids all year.
I think people obsess over serve mechanics because the serve is so important, and the technique is completely non-obvious. I had no clue about the racquet turning into the ball when I first started learning to serve. It's not something you really see when you watch a high level server as it happens so fast and you don't really know what to look for when you are first learning. So then when you actually do know what's happening it's quite a challenge to make that work in your own motion which is almost certainly already trained incorrectly. That makes it a struggle.
Anyway, it's worth spending some time on to learn it because when you do it opens up a whole new realm of possibilities for your tennis game.

The problem with tennis instruction and other sports too is, that they have sports spesific translations for common or physiological terms describing single joint moves and speak different language from what people know.
Any sport is doable, but the sport coaches have their own vocabulary and explanations for common terms, like pronation, which in the upper limb movements would only translate to forearm movement, not the ”tennis pronation”, which include the internal shoulder rotation to go with.
