Photos...
Here are analysis of photos if you don't want to open attachments.
I deleted arrows on second photo since it's a perception of angles...if he
rotated more away to the back fence, you'll see a great angle (flexion) in the elbow

OK...serve...
Nice stuff!
You already have plenty of comments so you need to weed out what's useful. And given you worked a good deal on the serve, I would let it develop more naturally from here on, at least for the next 6 months. I looked at the videos (frame by frame) and it seems you added some wrist flexion at the start which is good as it is a sign of relaxation. There's also some additional knee bend. His power (or trophy) position is fine. I wouldn't get hung up on it. I look more at the rotation and use cocking at the power position and of leg force and the launch position (with the racquet in the deepest slot and elbow at proportionally the highest and supination occurring). The biggest serves on the tour have good amount of cocking and supination naturally occurring in the last phase of the upwards drive. There's a great deal of talk about set-up which is less essential (therefore all these rhythms and stances, etc) and wrist action and pronation but that's preceded by slight supination in the launch position. It's created by a very relaxed arm position and powerful hip/shoulder drive resulting in a pre-stretched position. The trophy position is secondary, start, stance, etc are secondary. I believe you mentioned Mark at Revolutionary Tennis about arial views (I have several if I can find them) where you can the racquet head swinging away from the head while still in the launch position.
Two things for the future:
1) in the backswing (trophy position): rotation of the upper body, creating more separation angle, elbow cocking.
2) base: use of legs drive, not necessary getting farther into the court since he's using a platform stance but more upwards coordination and back kick. Getting 3-4" more upwards can produce a heavier serve. Because he doesn't have the leg drive, he tends to bend at the waist at the finish.
3) lower arm: allowing the last piece of the puzzle to happen, he straightens out and decelerates downwards. When he starts kicking the serve, he'll notice more use of the elbow in extension/flexion (at the end) and rotation. Yes, he could flex it 10 degrees more in the trophy position.
What he does extremely well now:
1) good power/trophy position. His racquet + lower arm could be straighter (keeping the wrist relaxed at the peak) in a line with a slight more elbow flexion.
2) outstanding flexibility in the shoulder/upper arm. Potentially this is the most important piece with the slight supination relaxation effect. Which separates the biggest serves from the rest (e.g, 140 from 110 mph). He gets into the slot beautifully. But he lacks the leg drive in the slot (he needs that force to happen, upwards and inwards/forward)
Ultimate it is #2 and his hand/speed...innervation of fast twitch muscles that will get him the best serve. Adding a bit more forward motion can help. Attached is analysis of good and things that can improve. Green is good, red can be improved. In the single photo, imagine if he rotated about 20 degrees more into the court with his hips/shoulders, where would the racquet be? It's already at a slight angle (North-Northwest...about 10-15 degree from north). Most players get a straight north position. Biggest serves get the 10 NNW position with added rotation (20 degrees)...that is the hard part since it requires delaying the load or upwards arm movement in exchange for more rotation of the shoulder and hips. If you observe when he rotates another 20 degrees, he loses this NNW slot position. That's difficult to do. So if he can, it can be impressive.

One last thing...
PART 10
The Conclusion ironically is The Beginning- The Set Up, The Toss and Attitude
develop...grow or cause to grow and become more mature, advanced, or elaborate.
Stotty...Beautiful work. Michelangelo would be proud. A living statue...in motion. Watch it grow...and develop.
Just one final thing now. Read this article "Elements of Serving Greatness" by Ed Atkinson and see the sections "Starting Position" and "The Toss". Read about Jack Kramer practicing his "placement" or in other words, his toss. Atkinson talks of Kramer reading the print on the ball. Worthy advice. If you have developed a perfect motion it will be all for naught, unless you put the ball in the right position to swing at it. Ed, wherever you are...I love you.
I agree entirely with Atkinson's analogy of Kramer's toss as being worthy of a model. What's more is that all four of these great servers in his article would agree with him...if they were alive. Don Budge personally taught me the same thing. The toss is to the right of the head and into the court. "G"'s swing is now calibrated to be most effective and trustworthy hitting the ball in this position...and there is only one point in time and space where everything is perfect.
Now that we agree as to where to toss the ball, the question is what is the most effective manner in which to deliver the ball there, in a repeatable manner. The answer to this important question lies in the set up. This is what I recommend.
In this video clip Roger Federer is in perfect position to deliver his toss to the exact and precise point where it needs to be every time. He is bent over at the waist so that his sternum is directly over his front foot. He has poised his racquet forward in his stance so that the hand that holds the ball is directly below the point where he would like to hit it. This is one of the most important aspects of a correct setup...and the one that I advocate. With one minor modification...Roger's idiosyncrasy in his set up is in the manner he begins his motion with his racquet already descended so the tip is somewhat down. My idea is to have the tip pointing at the target as if you are aiming a weapon...the Swedish major that I coach agrees. So does Eugen Herrigel in "Zen In the Art of Archery".
Speaking of aiming. Speaking of archery. Speaking of Zen. Don't forget good old Stan Smith's video on tactics.
The lines...in the case of the serve. Think of it as lining up..or aiming. Putting all of your ducks in a row. All of your energy...potential and otherwise. One line is formed by the end of the toes in a line to your target. Start your racquet on this same line...now you have two lines. The backswing more or less swings along this line or somewhat parallel to it. When you are at the top of your swing, your shoulders are in line with your feet. Toss the ball on the same line of your feet and on the line of your backswing, which is give or take directly over the right shoulder as you are delivering the racquet head to the ball. Harvey Penick would say that you are taking "dead aim" here.
In this set up position another very important aspect of the service motion is also optimized and that is the free swinging of the arm in the backswing. The way that the body positions itself in this set up, the arm is free to swing from the shoulder without the body impeding its freedom. Just by rotating or turning the shoulders all of your objectives that we have been discussing here are maximized...and your student need to no longer look for someone to mimic or copy. He becomes the model for your program in two years...maybe less. But as he stands now...he is a trifle too upright in his setup position.
Federer may or may not be one of the greatest servers of all time. He is one of the best of the modern era. Here he is practicing...and he is practicing being loose and having an "I don't give a damn because I know I am that good" attitude. This is evidenced by his stepping on the baseline when he is practicing. If you are a great server you have this sort of fatalistic approach to the serve...you know it's going in because you know your motion is perfect. If you miss the first, you swing at the second harder and with more spin because you know that it is statistically impossible to miss two in a row.
The other aspect of serving that goes along with this fatalistic attitude is in the manner the server approaches the baseline to assume his set up position. I have an idea that there is a door approximately two meters behind the baseline that the server enters every time he approaches the baseline to serve and when he enters this door he is in service mode. Sometimes the server may or may not pause and enter the doorway just reminding himself that he has a great serve that cannot miss. Sometimes the server might want to pause at this "doorway" on important points before he proceeds to the line and bounce the ball a couple of times in order to take the time to calculate or contemplate everything that is about to happen. The score, the target, his opponent, his strategy, the possibilities...etc. Visualize. Perhaps key in on the one swing thought that makes you a great server. Location of the toss, the sensation of the racquet falling behind you, total relaxation and confidence, for instance. Take your pick. It helps to be thoughtful before you hurl yourself into battle.
But Federer certainly does a lot of wonderful things in his book of service. Tactically he is very sound as he really moves it around the box with variation of spin and speed...although sometimes his first service seems to go a bit wayward in critical situations. Maybe that is related to the little idiosyncrasy in his set up...his rhythm may deviate just the tiniest bit under pressure. I am just speculating here. Usually he is great under pressure and that is because he has a great motion. And he believes in it.
This has been an amazing thread...and thanks a million for the opportunity to work with you once again. It was like a wonderful conversation.

Pancho
Interesting stats on the serve.
Pancho Gonzales had a 1st serve career average of 72 percent...not bad. I think Sampras's career average was around 64 percent.

I looked it up
I looked it up. It's pretty disappointing. Even if you compare indoors to indoors. Just go to the player on ATP site. Look up his record for a particular year and you can pull down the stats for a lot of his matches:
Stich against Edberg:
Indoors against Agassi at ATP Tour Championships:
Winning Vienna indoors against Siemerink:
Not nearly as good as I thought, but still a lot better than Berdych's serving percentages this week: 46, 46, 45 and today, 53, but he couldn't get his serve in when he needed it.

I'm saying he could be much better!

When you look at the "power" position in this video, note the orientation of the face of Berdych's racket as opposed to the face of Federer's racket. It's not just how low you can get this power position, to me it is how low you can get it when it is already moving in the plane towards the ball and the target. That's why the "backscratch" is a non-existent irrelevancy.
Take a comparison of Mardy Fish who is 3 inches shorter and about 20 lbs. lighter. Mardy routinely serves up to 140mph with a staggered motion, but he has a sound rhythm and great wrist action in his serve. It's an effortless motion.
Besides the point that Berdych's inability to get the serve in so often at key times is unacceptable, I think he could actually have had a more powerful serve with a little better mechanics. I think he is much quicker and actually more explosive than John Isner. Isner almost maximizes what he can get out of his serve, but he does not have the ability of Berdych to roam the baseline and I doubt he is even as powerful; nevertheless, he has put himself on the verge of being top ten with excellent technique and his obvious physical advantages, trying to hide his disadvantages (he's really slow!)
Most of all, he could have had a serve that he could have gotten in 70% of the time in the high 130's and low 140's. I think it might be possible to pull the stats out from archives at the ATP. I wonder what kind of stats Michael Stich had when he was winning Wimbledon back in 1992. And he was nearly 30 lbs. lighter than Berdych and just an inch shorter. He routinely served over 130 at a high percentage with no apparent effort.

The backswing is looking much more fluid than it is was, too. He doesn't have to think about this anymore.
G (not me) also noticed a funny thing from watching Stich on youtube. He noticed Stich sweeps into the "up together" motion almost directly out of his ball bouncing routine. There is no steadying or collecting himself after the ball bouncing. The ball bounce is virtually connected to his service motion.
G has been serve and volleying all this week in my absence. This has helped his forward momentum quite a lot. He likes to serve and volley and is exceptionally good at the net. His backhand volley is a stunning shot for someone his age. I'll post a clip of it at some point.
Don_Budge Of course you can write a post for G. Write a post for him whenever you want.
I'll let his serve bed down for a while, then I think more spin, more driving up to the ball, and a more forward ball toss (and more to the right) are in order. Beach ball here we come...

Debugged...Mission Accomplished

Ok...so here we are. The setup is fine tuned but needs just a little tweaking and the backswing is bebugged for all intents and purposes. Now we shall see.
1...The drag is gone. What you have in its’ place is a very elegant, very classic and very sophisticated backswing. See what tennis_chiro said about his rhythm...he's not kidding, he's not whistling Dixie. Some figure 8’s possibly but to me figure 8’s are only a means of getting there. He is there.
2...Yes, he gets it, I see the racquet head drop almost lazily...and you get it too, apparently. It’s a double dip, Stotty. I would not give any more thought to using Stich as an image to copy. It may only limit the young man...his motion is that good. Let’s develop “G”...to be “G”.
3...I want to write him a letter on the forum...is it ok with you?
4...Move on Brother, you have accomplished more than you have any right to expect. Move to the “weak link” in his game while he continues to develop his serve. I suggest putting the service priority on simmer for a bit.
5...Ahhh, Stotty. You underestimate the powers of observation that good old don_budge possesses. That ball is moving...and deceptively fast. The power is effortless and it's sneaky, therefore there is a lot of potential to be tapped in the future as the kid grows and matures.
6...Give my best to the wife and wishes for a speedy recovery.
PART 8 "To be" vs. "to imitate"...development (beach ball, launch and serve and volley drill) is still in play...I am very curious as to what this missive will produce. One more peek at video after this idea is introduced to the kid. The toss needs to be moved to the right in order to spin the ball...soon to be addressed in PART 10...The Conclusion.
I see the image of the racquet head arching to circumnavigate the beach ball.
I see the "snakiness" of Nastase in the first serve. Uh oh...!!!
Forget Stich...my money is on "G". This clip tells me to move the toss a bit to the right.
My next tip about the setup is from this clip.
http://youtu.be/YKdPoXCjEOg[/QUOTE]
Beach ball, bingo...boom! Bing, bang...bye!
Unbelievable!!! It's that good. I would like to pay you a compliment as well...nice job on the camera, the feedback and your general overall professional approach. You do your student a great service. It's definitely a pleasure working with you...as usual.

I have done it before on Tennisplayer and the reaction from students is the reverse of what many would think. G is flattered by the input from other coaches and by the efforts of others as well as myself to help him. It motivates him…makes him feel like a worthwhile tennis player...makes him grateful, too.
I am not going to move on from trying to de-bug the backswing. I feel time spent here could pay big dividends. But as DB says it's time to settle for what we have at the moment and switch the emphasis. We did work on spin today which he enjoyed and succeeded at.
Shame the clips can't give you all an idea of pace. I have restricted him to three-quarter paced served thus far…but despite this the ball is moving pretty quick.
No more posts until Wednesday, earliest. My wife is having four kidney stones removed in a London hospital and needs my moral support. I will follow the thread if I can connect to a wireless network somewhere.

Repost...
PART 5
Fine tune, Debug and We shall see
develop...grow or cause to grow and become more mature, advanced, or elaborate.
Finally...with regards to your last video of the impromptu 45 minute session. You are absolutely on the right track...it's all about the setup and the backswing.
1 Fine tune setup...lean a bit more forward from the waist. Bobbing racquet head with arms and shoulders. And a one...and a two...and a three, and a here we go. Or, one for the money...two for the show...three to get ready....and go cat go.
2 Debug backswing...small almost imperceptible pause on the way back. By swinging the arm and racquet in one position, and as one unit all of the way to the top of the backswing this small pause will disappear.
3 We shall see where we stand after points 1 & 2. Arm action and footwork were very good at the beginning...it should be even better now. The more comfortable he gets, the more his shoulders will turn quite naturally.
I am very, very impressed with your last video and eagerly await your next submission...from the tone of your words.
PART 6
One last thing...the figure 8
develop...grow or cause to grow and become more mature, advanced, or elaborate.
By creating the new path with a modified setup and drop of the racquet head initiation of the swing..."G" has a nice big circle in front of him that is his backswing. Coupled with the nice big circular motion that he already had behind him, what have you got?
Answer: Don's figure 8.
PART 7
Sam Snead, Olof's flimsy shoes and The Roller Coaster of Love..."Deliverance"
develop...grow or cause to grow and become more mature, advanced, or elaborate.
Originally posted by licensedcoach View PostThe thing is with Stich when I watch his serve over and over again, there is no hard pressing down with the front foot... nor is there any hard pressing down on the back foot...it's all so gentle, relaxed and easy...it's almost weightless to look at...yet it's weight transfer to perfection.
Re the pause in the backswing, I had completely missed that one.
2 Debug backswing
Is the key to achieve the above relaxation, gravity? I think because he is trying to control his arms thru an unfamiliar swing path he is a little tense in the arms...might take this on this weekend and see what I can come up with.
I think you have answered your own question here about the debugging of the backswing...
The quote below is from my post titled "Roller Coaster of Love...Part 1" (From the "Racquet snaps the wrist on serve..." thread, tennis_chiro and I sound a bit like the dueling banjo's in the movie "Deliverance" in that thread. It's currently on page six in the forum.)
"Here we go...hold on to your hat! One thing that we must clarify before we go into any kind of explanation about the motion is the pressure of your grip. Sam Snead referred to the grip on his golf club as holding it with only so much pressure as you would hold a live bird. We only hold on with our hand tight enough to not let go of the racquet. We maintain only enough pressure in the entire arm, forearm and wrist to swing the arm and racquet back into position in one piece without disturbing the exact position that it is in at the setup position. We must eliminate all sources of tension and resistance when we are attempting to use pure gravity to dictate our motion. From this relaxed and confident position at setup we need only to release the racquet with our left hand that is supporting it, and allow the weight of the racquet head to merely fall upon the line of the track all the way back to the fence until it reaches a position at the top of the hill."
Now the key to all of this is to keep it as simple as possible. I like my little story about the serve metaphorically as a roller coaster supported by the visual image of tennis_chiro's figure eight's clip.
PART 8
"To be" vs. "to imitate"...development.
develop...grow or cause to grow and become more mature, advanced, or elaborate.
Elaborate (a musical theme) by modification of the melody, harmony, or rhythm.
Originally posted by licensedcoach View PostIt's not easy what he is trying to do...emulate Stich that is. We'll get there.
"G" now has the beginning of a sound fundamental basis for the service motion. Before imitating a professional tennis player who had been perfecting his service for fifteen years, perhaps it would be prudent to proceed one step at a time. Let "G" develop into "G" as opposed to imitating Stich. He can borrow some things from Stich perhaps, as well as Federer, McEnroe, Brosseau...but it will be better for "G" in the long run to learn to be himself. The key word is develop.
Now...with a nice motion in place, and as tennis_chiro suggests with some practice it will take some time to become second nature to the boy...let's focus on spinning the ball a bit. Afterall, that is the purpose of developing this serve, isn't it?
Have "G" imagine that the tennis ball is as big as a beach ball and have him try to throw his racquet all the way around the beach ball to create as big an arch in his motion as he can. Toss the ball at one o'clock and a bit further forward into the court. This should loosen up his arm a bit and get him to toss the ball a bit more into the court...in order that he "launches" himself at the ball. Work at this with a variety of speeds. Work on this from a meter behind the baseline. Nice and easy at first...relax the arm for the full potential effect. Learn to keep the arm relaxed as you turn up the heat. Think big circles. "And Then There Were Three" (circles)...Genesis.
At the same time incorporate some serve and volley drilling so that his motion is directed into the court...or rather to the target. After he has the concept of the motion it is time to attempt to incorporate the motion into play time. Having the motion stand the test of match play is the final phase of development. Time to let up on the service details some, I think. It's more like a feeling than a definition. It's more of an imaging process, ala Yandall, than a matter of mechanics at a certain point. There is the danger of overload or as you put it...preoccupation, which is somewhat natural. It's like a new toy, isn't it? Don't wear it out. Let's be somewhat cautious of his arm as well. Let's keep things in perspective. Let's create curiosity on the student's part.
Looking good...and steady as she goes. There is no hurry now. Just be patient and see what develops. He's only fourteen...there is only so much room in his noodle. Rome wasn't built in a day. Neither was the British Empire.
vrc10s...I like the idea of building from the feet up, it's good to have a sound foundation.

I couldn't get on court with him today because he had a ratings tournament in London. He won one match and lost the other. I wasn't there but he said he played badly but served quite well. He says he is preoccupied with his serve and finds it difficult concentrate on points as well - understandable in my view.
