Dick, Thanks again for the Stroman analysis. Regarding the amount of bend in the back leg at touchdown, it seems that pitchers like Greinke and King Stroman who have a lot of bend in the back leg at touchdown come up on their back ball of the foot and “squish the bug”, while other pitchers such as Chapman and King Felix have a much more straight leg at touchdown and tend to roll their foot over. Can you comment on the two different styles and give your thoughts? Here is video of Chapman and Felix: https://www.youtube.com/watch?v=TcmfxFDU8I4 https://www.youtube.com/watch?v=n8LDipM5NWk
Dick, Over the past 7 years, I’ve watched you correct pitchers for not having their foot parallel against the rubber because it’s a cause of early hip rotation. If the front part of the back foot is positioned ahead of the heel, that will encourage the back knee to turn down and in prematurely instead of keeping the knee over the foot while pushing with the back leg. How much ahead or in front of the heel should the back toes be? Is this a permanent change or just one to help David get the feel of what he’s supposed to feel and then he goes back to his foot parallel against the rubber? Thanks for your help.
Thanks, Dick. I think the problem is that David uses his back leg well to move down the mound fast. He may not know exactly when to stop pushing and come up on the back toe. He’s afraid if he comes up on the back toe too soon, he’ll start early hip rotation. We just don’t want to kill his back leg drive so we’ve been careful about how we approach it. We’ll discuss the option of starting with the back to below the heel on the rubber. Is there another way to approach this that you know of?
Sorry. The weather got us yesterday and all I could get was the side view.
Dave, what’s his stride length?
Dick, At 1:34 of the video, there is a side view.
Dick, Related to his back foot…Until a couple of weeks ago, he used to just roll his his back foot over onto its side and not even come up on the ball of the foot at all. So, he has made some progress in that area. He knows when the front foot starts to turn, the back foot should be coming up on the toe. He tells me that he wants to push with the back leg all the way to landing and that its difficult for him to know when to stop pushing and come up on the back toe. Any pointers is appreciated.
Thanks, Dick. David’s very motivated right now but he’s about to drive me nucking futs with getting to 90 mph.
Jim, Do you have video you can post? What’s your son’s velocity? Was your son diagnosed with Medial epicondylitis? From what I read, your son was shut down for 7-8 weeks before he threw his next bullpen? If he was shutdown that long with no throwing, he should slowly work his way back to the mound over a period of a couple of weeks.
Dick, How do you think David looks from the stretch above from his bullpen yesterday?
Dick, Bullpen from today, all 3 angles. He was working on coming up on the back toe sooner in this bullpen. Also, he knows he has to keep his throwing arm elbow in close to his side so he takes the ball out of the glove better. We’ll work on that next. http://youtu.be/pjApK-PvBjE http://youtu.be/-RP8VKB2Hjw http://youtu.be/_JGjn-gcMvo
There’s a kid on David’s Summer team that throws 87 mph. He said to me, “Dad, how is it that I’ve been learning and working my mechanics for 7 years now and this kid is out throwing me.” What do I say? In your book the “The Science and Art of Ptiching”, it says (pg. 5.32): “…Often pitching velocities improve in LL and HS players as a result of growth and maturation despite the instruction or coaching they receive. When attributing coaching successes to the use of emphasis suc has those illustrated here, such judgements must always be tempered by the consideration of the pwerful performance influences that occurs in boys and young men at the stage of puberty and during adolescence.” David’s not shaving yet and although he’s a big boy he has a “baby face” and is still growing. How much of a velocity pickup do you think he’ll gain by maturation and “becoming a man”?
Thanks, Dick. David’s next bullpen is tomorrow (Wednesday) so I’ll have 3 views then. Yes, for the last 4 bullpens David has been working on coming up in the ball of his back foot sooner to get his hips open at landing and also to get the front foot directed at the target. He’s had this slightly blocked off front foot problem for a while and we’ve worked on it off-and-on but never sealed the deal. This fault is what’s causing him to reposition his knee at landing, which causes him to brace up later than he should.
Dick, David does his core workout 5 days a week; his upper body (scapular, shoulders, forearms, med. ball, etc.) 3 days a week and his lower body (lunges, one legged exercises, squats, etc.) 3 days a week. Year ’round. Below are 2 videos from his last bullpen last week where he was working on coming up on his back toe earlier to open up his hips at landing. Unfortunately, rain was closing in on us and I only got the side view done. The stretch video is how he pitches all the time, but we are adding the step back this fall. He has just begun to work on the step back wind up. We would appreciate your comments on how that looks as well. http://youtu.be/_I5zRi74B2w http://youtu.be/TLBZL8ea7UY Randy
Jose, I know Dick will be along soon to elaborate on your son, but thought I’d comment real quick. From the back angle, you can see that he is collapsing his back leg (knee drifting out past the back toe). This is caused by him not having weight shift prior to hand break. From the side view, see how his head doesn’t move at all before hand break? Then all his energy goes down into the ground instead of the target. Second, from the front view, he’s landing to the 3rd base side of the mid-line. He should be landing on a line drawn from the middle of the posting foot by the rubber down the mound. His posture at landing is preventing his hips from opeing up to assist trunk rotation. Best of luck. He’s a good looking young man.
