Stretch Wind-Up compared by Coach Coral

[Integrity32]

Only problem I have is that this is all qualitative data. I know all comments on here are old but for anyone watching this, Max External rotation for the shoulder joint shows 1.2-1.5x the angular acceleration during the wind-up vs the stretch meaning the risk of injury is greater. Studies also show ( you can see by watching baseball games ) that maximum ball velocity does not change during the wind-up to stretch. So why use the wind-up at all???

Excellent explanation! I've read the rules in the rulebooks and on wikipedia, but this little simulcam presentation makes it much clearer. Thanks for posting!

Thanks, we will tell coach Corall if you go to our TV website (not the dotcom but dotTV) search for the collection best of Diamond SPorts...you can subscribe to many great explanations

the wind up and the strech cant be the same, right now are the same because he is not taking any momentum out of the wind-up,

you have to take a big step back out of the wind-up to get better momentum, its like taking a crow-hop out of the strech basically you are just throwing the ball without momentum, so they cant be the same,

if they are the same youre waisting your time and arm out of the wind-up

[mikeykirsch]

you dont take more than a six inch rocker step or else you will lose balance early in the delivery and therefore will lose velocity and more importantly, control.

[alaestia]

how you will lose balance you take a step back to increase the distance to the plate and to push with both legs and you will increase velocity and control and you have to take like a 30 inch step back try this on your next session if you pitch,

your a complete idiot

this is good so people cant steal

[PackersBearsFan3]

He got it right the first time. You want to be quicker to the plate. Bringing the leg up higher impedes speed of movement, which takes away from velocity.

This pitcher needs to move much more explosively (while leading with the front hip)

a 100% stride length would be ideal, and would definintely help in more velocity and (in theory, all good mechanics considered) better control

awsome
