  • Pitching analysis - 9yr old

    Hello - I recently posted a video of my 9 YO son's swing and received some nice feedback and things to work on from you all. I was hoping you could do the same with his pitching... any and all feedback is welcome! Thanks in advance.

      “any and all feedback is welcome!”
      Your son does some things very well from our particular approach.

      He tries to stay tall but still has his ball side leg recover up and over like he was recovering with back bend. The intuitive recovery position of approaches that use tall posture is by leaving the ball side leg down so it can be punched thru and add in full body rotation.

      He limits his rotational effort by finishing with his pelvis and shoulders 90% lateral to the field driveline (imaginary ground line between home and second)squared up giving him only 45 degrees of useable rotation while driving the ball and now in a lesser defensive position .

      Ask him to recover by rotation off the glove side leg powerfully pulling back against the glove side leg and glove arm by recovering 175 degrees, leaving you in a “drop step position” perfect for defensive first reactions with both feet on the ground at contact.

      He pulls his Elbow down and across his abdomin indicating forearm supination while driving the ball, very dangerous!. Have him pop his Elbow up and voluntarily forearm pronate all his pitch types”

      His arm recovery will now end up still inline with his shoulders and the hand end up out in front by his back ball side hip because he now body rotates 175 degree.

      Start with these and have him stay with the set position, nothing is gained with a pre wind up or leg lift.

      Good luck, any questions, go for it.

        Dirtberry - I appreciate you taking the time to write all that... thank you. There is a lot here for me to digest.

        I see what you are saying about him only using 45 degrees of rotation and stopping short. How can I get him to rotate more? Is there something he is doing that is causing him to stop short or should I simply tell him to rotate more? Maybe a drill?

        What you said next concerns me... "
        He pulls his Elbow down and across his abdomin indicating forearm supination while driving the ball, very dangerous!". He is a strike thrower so is used a lot... need to fix this right away. Is there a drill or something simple you recommend?

        Thanks again

          Is his plant leg knee pointing toward 3B? If so, it would seem like this could promote future MCL pull/tear or psoas/hip issues.

            Got a chance to watch and agree with Song.

            Why is his leg planting towards third base and his body is rotating off of that leg? That's not good in the long term and if he starts throwing harder and using his body more, he'll injure his knee.

            I much prefer he sweeps his leg out to learn how to drive towards the plate and when he plants, it's not on the side of the knee but bracing correctly as he throws forward and not from the side. Hope it makes sense. His hips should rotate around, but his knees shouldn't be doing that, it should be flexed and little movement.

              Thanks Modal - makes sense. We have been working on his foot planting toward 3rd and is now much straighter toward home plate. He is pitching tomorrow so I'll get some new video.

              What are your thoughts on pitch count per week/year at this age. As I said he is a strike thrower so his coaches want him to pitch every game... I don't allow it. I let his coaches know he is not to pitch more than 2 games a week with proper rest in between, no more that 90 pitches a week and 1000 for the season. I count every pitch myself. Am I too conservative?

                We did 3 innings max, and less if they were struggling, or their typical FB pitch speed dropped 3-4 mph. We had one kid (maybe 12U?) that played summer travel beyond rec, and pitched too much, and blew his shoulder growth plates and he never pitched again. It worked out for him, he was drafted as a hitter.

                  Hi got some really bad news last week. About a month ago after pitching an inning my son said his shoulder hurt a bit. I did not allow him to throw for a few days and had him start back lightly. He said no pain but I kept him off the mound for 2 weeks. After the 2 weeks of no pain and light throws had him throw a bullpen, pain came back. At that point I shut him down made an appointment with an Ortho sports specialist.

                  Turns out he has little league shoulder (separation of growth plates). They have him in a 10 week rehab program and no throwing (or hitting) for at least 8 weeks, maybe more.

                  I feel so bad for him. We plan on shutting him down for the year and not let him back on the mound until we know he can throw safely (maybe never), so no reoccurrence.

                  He is 9 and has been clocked at 58mph, has not pitched more than 50 pitches in any single game this year and never more that once or max twice a week.

                  Just feel horrible and sick to my stomach about this

                    But to the dads out there it is an overuse and poor mechanics issue. Make sure your kid throws correctly and limit it.

                      Sorry to hear about your son's diagnosis, but pleased to hear to were so attuned to seeing the signs, and getting him into see an ortho as soon as you did. Unfortunately, too many parents don't think anything can happen to players at this young of an age, and simply chalk up the pain to being just being tired, didn't warm up properly, played too much over the weekend, and a myriad of other excuses...instead of getting it checked when it didn't resolve itself after some time off, and rest.

                      If/when you decide to let him pitch again, and even just getting back to throwing...I would suggest a much longer conversation with Dirtberry as to the proper mechanics, kinesiology, and physiology of throwing anything...especially a baseball.

                      Best of luck going forward, follow the doctors' recommendations and rehab timeframes, and you'll both be surprised at how quickly those 8-10 weeks will be, and he'll be back at it once again. Just make sure he's throwing correctly in the future, but that kind of goes w/o saying (although I did say it...Lol).

                        Sorry about the delay, my desktop crashed when I plugged my phone in to charge it. This morning after a month of ignoring it, I plugged my phone in again and it started the computer? go figure.

                        “I see what you are saying about him only using 45 degrees of rotation and stopping short. How can I get him to rotate more?”
                        Making him aware early that their are some pathos busting tenets in mechanics can set him up for future curiosity and learning in this field!

                        One of these tenets is to always keep your Humerus centered in the Glenoid cavity when you drop in, drive and recover your body and arm! This means keep the Humerus in alignment with the tips of the shoulders (acromial line) at all times. Another is always throw forearm pronated pitch types

                        The best drill for this, is good for so many arrival, drive and recovery components.

                        “The no stride drill”

                        Stand with your glove side leg forwards the distance of a “power walk step” (not long) with the foot slightly open to the plate. The ball side foot turned 20 degrees towards home plate.

                        Start by pendulum swinging his arms simultaneously by dropping them down then split, then upwards with the ball arm outwardly rotating (forearm supinating) where you end up with the ball at "driveline height" (top of head) reached back with slight bend in the Elbow and hand under the ball (this is arrival).

                        making you arrive before you start the first acceleration. The glove arm should inwardly rotate and point directly to the target by arriving also simultaneously. This now has had you learn how to keep your glove and ball above the “field driveline” (imaginary line between home and second during drop in lengthening to arrival. he should perform this smoothly and contemplatively to then turn on the acceleration by shortening.

                        When he starts the first acceleration phase (rotational) his mental effort should be in maximally pulling back on the glove arm and glove leg by pulling the glove right back towards his glove side cheek by supinating his forearm and outwardly rotating his Humerus. Emphisis on the glove leg pull will engrain better rotational ability. He should immediately raise his ball side elbow upwards while driving the ball and forearm pronate all his pitch types. These maneuvers should also have the ball side Humerus stay in alignment with the acromial line during drive!

                        When he starts the 2nd acceleration phase (linear) he should keep his elbow high and not pull it down while explosively rotating 175 degrees with the legs, Pelvis (acetabular line) and shoulders where you see his ball arm recover out straight towards the plate then coil down, try to put your hand in your back pocket. You will notice the Humerus stays more in alignment thru the whole delivery.

                        He pulls his Elbow down and across his abdomen indicating forearm supination while driving the ball, very dangerous!".
                        I feel so bad for him. We plan on shutting him down for the year and not let him back on the mound until we know he can throw safely (maybe never), so no re-occurrence. “
                        Not to worry, let him start throwing again when he get's his dr's release, He has what's considered a broken bone, unfortunately it's right in the middle of his proximal Humeral growth plate. It's treated like a broken bone 6 to 8 weeks of shut it down. This growth plate, the largest in the upper body was broken by deceleration traction where the pectorallis major is flexed because he horizontally drove his Humerus and when it turns the corner of the shoulder the Humerus slams across the flexed pec to recover the arm and levers the Humerus away from the glenoid cavity actually dislocation the head of the Humerus also causing laxity at the posterior shoulder ligaments.


                        Satisfy the tenet that eliminates the problem!
                        Teach him to recover his arm in line with his shoulders, it's that simple but takes some remapping.
