High school pitching mechanics - flaws that reduce velocity

[MrPitchingmechanics]

Hey "LeftyDM" Can you take a look at my video and let me know how im doing? Im pretty sure I open too much prior to my front foot landing. also is my arm angle to low?

[leftyDM]

Turning has little to do with producing separation. Any pitcher can move in a direct line to home plate and still have the throwing arm and shoulder back at landing if he understands how to use his back leg. Ranger's Feliz, who throws 100 mph is a good example of that. He has not turning in his delivery. It is all about timing and how to use hte back leg...not turning or counter-rotating. Dick Mills

@leftydm turning the hips can actually increase velocity, mostly because it allows the hip/shoulder separation to become more effective, not so much because it allows your LEGS to give more power. By twisting the hips they can explode better upon landing foot's impact (rubber-band effect) and this quick explosion is too fast for the upper torso to keep up...this causes a stretch and separation between the torso/shoulders and the hips, which in turn allows you to throw harder.

it doesnt sound like u know much about baseball because when you turn you can get more leg power and thats were most of your velocity comes from

[leftyDM]

The science and biomechanics are quite clear on this issue. To maximize velocity weight shift (linear momentum) must occur before any rotation. Rotation should not occur until landing. Rotation over the back leg is wasted energy that cannot possibly end uip as more force or velocity.

@leftyDM Actually it can help you gain velocity. Turning like that will allow you to use you lower torso as another force you can add to the throw. Its like coiling up a spring.

Very cool Thanks!
