  • Raducanu's Serve

    Emma credits a British "technical consultant" with major improvements in her serve, although I can't find anything specific on what they did.
    "Improved flow"? Anyone know?

    From Simon Biggs at The Telegraph, link to free copy on Yahoo:
    Why was Emma Raducanu so emotional on Sunday? At first, we travelling reporters ascribed her tears of joy to the relief of getting one back on Marta Kostyuk – a fellow 19-year-old who had beaten her a couple of times as a junior. But we were wrong.



    “I've never played on clay before, professionally,” said Raducanu on Sunday night ... Against Kostyuk, Raducanu’s service statistics were outstanding. She landed 77 per cent of her first serves and barely lost a point when she did so. This was a major improvement from Miami in late March, where she was rolling the ball into play with little conviction or penetration.


    "Her technique on serve is a work in progress, changing from week to week. Or, at least, it was. Since the start of April, remedial work with the experienced doubles coach Louis Cayer – who also rejigged Andy Murray’s serve in 2016 – has improved the flow of the motion. The result is more punch, more accuracy and more confidence.

    “I definitely think that he added great insight,” said Raducanu of Cayer. “I feel like he's obviously a really renowned coach in the UK and he's got tons of experience so just to pick his brain a little was really great for me.

    “When my serve percentage has been low and also slow. I've been running a lot and getting myself into very long rallies. Then the match gets more and more physical. I really need to step up my first serve.”

    ~~~~
    And elsewhere:

    "“I was just reflecting on that and I was like, ‘Oh my God, like 365 days ago, I was literally sat in an exam hall doing maths paper three,’ ” Raducanu said. “I would have taken everything that’s happened and dealt with any sort of downs or losses or whatever those feelings are, if you would have given me what I’ve had in the last year.

    Are there any specifics on what Louis Cayer changed?

      I can't find any. One reason I posted is that I hoped some reader that understands serving would have seen something. Please ! ?

        It would be nice to know what they were working on in this clip https://www.youtube.com/watch?v=pxOQqxKXChM . At 1:35 the coach is simulating something but I can't work out what. If I could edit the clip into back-to-back before and after serves, we may be able to work it out. She has been working on her serve for a while apparently but it's tough to find any discernible difference.

        Not sure what the cardboard box is about. You'd think by this point she'd have a ball basket.

          Or a sponsor that sells balls ... and its basket Thanks for sharing.

          That's Torben Beltz isn't it?

          Maybe this didn't work & that is where she decided to fire him

            Its difficult to really find quality slow motion videos of Raducano's serve, either before or after the changes. Things that really stick out to me as potential problems on the before serves:

            *1) Very high toss
            2) Front knee (left) position in full knee bend at the toss. Knee should be over the toes but bends in towards the back knee. On some serves her knees are almost touching.
            *3) Legs don't initiate racquet drop. Legs/knees straighten before racquet exits the backswing. Out of synch.

            Curious about her diagonal swing plain

            4) Not enough hip over hip in the leg drive up. Both hips are similar height and hips face net at contact more than advised.
            5) No 180 degrees of ISR, before and after contact.
            6) Racquet head not tilted to the left of hand at contact. Hand and racquet are in a straight line on some serves.

            * - designates potential timing issues

            I'll keep searching for explanations of the suggestions of Cayer.

              Great walk thru on Emma's serve. You are without doubt the most forensic coach on the forum. Might not curing 6) cure (5? I find there are two killers of ISR that reside in the ball toss; ball toss too far to the right or ball toss too far in front. The problem with someone like Emma is her limited ISR might be very 'grained in' through deep rooted habit. Popping the ball toss more to the left might not do it like it can with juniors where the problem is dealt with more early. Someone is bound to have tried this already with Emma I imagine.

                  Think Coach Cayer noticed all the same things?

                    Louis Cayer is one of the few coaches that I would go out of my way to watch one of his presentations. I have learned valuable information watching some of his presentations at ITF World conferences (ITF Website). Not sure of his personality but he knows his stuff.

                      Found this on Youtube. 1 Hour & 11 minutes of Raducano's slow motion serve. Mostly rear view but has 3 segments of side view (28:10 - 35:28, 45.54 - 53:12, 103:39 - 1:11).
                      Did I mention before about slight lateral pinpoint stance, not loading back hip well.

                        Good find. Legs are terrible. No ISR...

                          I can see no ISR

                          But is the legs terrible because of back leg loading? Or the position of the back foot?

                            Raducano's lateral pinpoint service motion has some similarities to Jenson Brooksby's platform stance in that both have weak knee positions in the loaded position that lead to less then ideal leg drives. They collapse forward on the leg straightening instead of having a strong vertical upward movement. Must first go up then forward. If you look at BG's 3 parts to the upward swing (serve), its not until the 3rd part (ISR, Wrist flexion to a neutral position & upper torso twist rotation) that the swing goes forward into the court.

                              There's a very good example of Louis Cayer's teaching style in the seminar "Technical Training? It depends". Its from a 2016 ITF World conference. He explains his basic philosophy when working with a world class player. He focuses his attention in 3 areas - 1) timing 2) rhythm 3) momentum. Rhythm deals with the racquet and momentum deals with the body. For both, he wants to see a noticeable change of speed at contact. Come to the ball with care but have a noticeable change of racquet head speed and a noticeable change of angular momentum of the body at contact (180 degrees of shoulder rotation). Interesting.
